B-001-001 – Radio Licences, Applicability, Eligibility of Licence Holder

Amateur radio in Canada doesn’t operate in a vacuum. It exists within a well-established legal structure that defines who can participate, what privileges they have, and how radio stations must be managed. Before touching a microphone or key, every amateur must understand where the authority for amateur radio comes from, who enforces the rules, and what documents define the service itself. These foundational principles are the starting point for every new operator.

❓ What gives amateur radio its legal foundation in Canada?

Before anyone in Canada can legally transmit on the amateur bands, they must be licensed—and that licensing authority must come from somewhere. Amateur radio

exists within a well-defined legal framework, ensuring that operators follow national guidelines for equipment use, frequency access, and communication practices.

These rules also help protect the amateur spectrum from both intentional and accidental interference.

At the heart of this framework is the Radiocommunication Act. This Act gives the Canadian government the authority to create and enforce regulations that govern radio operations. It is the document that underpins everything from licensing to technical standards. For example, the Radiocommunication Act specifically assigns the power to create regulations governing radiocommunications, including the amateur service. It also authorizes the

publication of technical standards such as the RBR-4 Standards for the Operation of Radio Stations in the Amateur Radio Service in Canada. Without this legislative foundation, there would be no formal standards for amateur radio to operate within Canadian law.

B-001-001-001, B-001-001-002

🏛️ Who manages the rules once they are created?

Once the Radiocommunication Act defines the rules, someone needs to administer and enforce them. That job belongs to Innovation, Science and Economic Development Canada—often referred to as ISED. This federal department handles the day-to-day management of spectrum access across the country, including amateur radio, commercial broadcasting, cellular, and more.

For hams, ISED is the department that issues operator certificates, investigates interference complaints, and sets national policies on spectrum allocation. When you apply for a callsign or have technical questions about your station’s compliance, you’re working within ISED’s jurisdiction.

B-001-001-003

📖 What defines amateur radio in Canada?

While the Radiocommunication Act lays the groundwork, the detailed rules that define the amateur radio service are found in the Radiocommunication Regulations. These regulations specify what amateur radio is, who qualifies, what privileges they get, and what limitations apply. They’re the practical guidebook that turns legal authority into operating reality.

The Radiocommunication Regulations outline expectations for operator conduct, station identification, power limits, and frequency usage. They ensure the service remains non-commercial and focused on technical learning, experimentation, and emergency support. This document plays a key role in preserving the spirit of amateur radio while also ensuring consistent national standards.

📡 Final Transmission

Canadian amateur radio is built on a legal and regulatory foundation that ensures it operates smoothly and fairly. The Radiocommunication Act provides the authority to regulate, Innovation, Science and Economic Development Canada manages the system, and the Radiocommunication Regulations define what the amateur service is and how it must function.

Together, they ensure that every Canadian ham operates under a clear set of standards that support technical learning, public service, and responsible communication.

B-001-002 – Licence Fee, Term, Posting Requirements, Change of Address

Changes in address, lost certificates, or even call sign upgrades are part of every ham’s journey and understanding the requirements around fees, certificate validity, and address changes ensures that you stay compliant with federal regulations and avoid penalties or lapses in your operating privileges.

This section focuses on the core responsibilities every amateur operator in Canada must know about their certificate: how long it’s valid, where it should be stored, and what to do when you move.

📨 What should you do when your address changes?

When you move, your Amateur Radio Operator Certificate doesn’t automatically update. You are required to Inform Innovation, Science and Economic Development Canada of your new mailing address. This must be done within 30 days of the change. Not doing so can result in administrative complications or delays in important notices from ISED.

Remember, you must notify Innovation, Science and Economic Development Canada within 30 days of a change of mailing address. This ensures your contact information stays current in the national licensing system and that your certificate remains valid.

B-001-002-001, B-001-002-003

🪪 How long does your certificate last—and where should it be kept?

In amateur radio, passing the Basic exam isn’t just a milestone—it’s a lifetime achievement. Once you’ve earned it, your Amateur Radio Operator Certificate is valid forever. It doesn’t expire, and there’s no need to renew it. The qualification is yours for life, a permanent recognition of your status as a licensed Canadian amateur radio operator.

But with that privilege comes an important responsibility: the certificate must be accessible when needed. According to the regulations, it must be retained at the station. This means it must be physically present and available where the station is located. If a radio inspector asks to see your Amateur Radio Operator Certificate, or a copy thereof, you are legally required to produce it within 48 hours. Keeping your certificate handy isn’t just good practice—it’s part of staying compliant.

B-001-002-002, B-001-002-004, B-001-002-005

🏠 Where should your certificate be kept when you’re not operating?

Many hams assume that if they’re not currently on the air or don’t have a home station set up, the location of their certificate doesn’t matter. But the regulations are clear: it must be retained at the address provided to Innovation, Science and Economic Development Canada. This helps ensure consistency in enforcement and clarity if there’s ever an audit or investigation related to your callsign.

Having your certificate at the address you provided helps you demonstrate compliance, especially during times when you’re not actively operating but remain a licensed amateur.

B-001-002-007

💰 Are there fees for issuing or changing your certificate?

There’s good news for new operators: the initial cost to become licensed is Free. Likewise, if you move to another province or territory and request a new call sign prefix to reflect your location, that update is also Free.

However, if you want to change your current call sign voluntarily—such as upgrading to a two-letter suffix—there is a fee. That cost is 60 dollars.

B-001-002-006, B-001-002-008, B-001-002-009

📡 Final Transmission

Canadian amateur operators must remain diligent in maintaining their licensing responsibilities to stay in compliance. The certificate of proficiency is issued for life, but it must always be kept either at the station or at the address registered with Innovation, Science and Economic Development Canada. Operators are required to inform the department within 30 days of any change of address and must be able to present their certificate within 48 hours if requested. Routine administrative updates are free of charge, while optional changes, such as applying for a new call sign, require a $60 fee. By meeting these straightforward obligations, amateur operators ensure their continued legal operation and uphold the standards of the service.

📘 B-001-003 – Licence Suspension or Revocation, Powers of Radio Inspectors, Offences and Punishments

Operating in the amateur radio service comes with privilege—but also responsibility. These responsibilities aren’t just moral or technical, they’re legal. Canada’s Radiocommunication Act and associated regulations set clear boundaries, enforce penalties, and empower inspectors to investigate violations. Understanding where those lines are is important to maintaining your certificate and protecting the amateur bands.

In this lesson, we’ll look at what kinds of actions can get an amateur operator into trouble, from out-of-band transmissions and false distress signals to interfering with legitimate communications. We’ll also explore the powers of ISED and radio inspectors—what they can do, and where their authority stops.

🚫 What happens if you transmit outside the amateur bands?

Each amateur operator in Canada is authorized to transmit only on frequencies allocated to the amateur service. Going beyond these limits—either intentionally or accidentally—can create interference to sensitive services like aviation, marine safety, or emergency communications.

To prevent this, transmissions outside amateur bands are prohibited and penalties could be assessed to the control operator. It’s the control operator’s legal duty to ensure their equipment is operating within assigned boundaries.

B-001-003-001

🆘 What are the consequences of faking an emergency?

Emergency phrases like “MAYDAY” carry life-and-death weight. Using them without a genuine emergency isn’t just irresponsible—it’s illegal. If an operator falsely transmits the word “MAYDAY,” it’s considered A false or fraudulent message under Canadian regulations.

Transmitting false information is never permitted, and potentially risks diverting emergency services, delaying aid to real victims, or interfering with emergency or commercial stations.

B-001-003-002, B-001-003-007

⚖️ What penalties could you face for serious violations?

Some offences—like false distress signals or intentional interference—go beyond technical violations. These are criminal matters under the Radiocommunication Act, and they carry serious penalties. If found guilty of either, the offender may be sentenced to A fine, not exceeding $5 000, or a prison term not exceeding one year, or both.

This penalty applies whether the violation was a prank, an act of defiance, or simply reckless behavior. Even if no harm was intended, to interfere with, or obstruct any radio communication, without lawful cause is considered unlawful and is taken seriously under federal law.

B-001-003-003, B-001-003-008

📜 Where are these rules written down?

All offences, penalties, enforcement powers, and legal definitions related to amateur radio in Canada are laid out in the The Radiocommunication Act. This law authorizes ISED to issue, suspend, or revoke certificates, defines illegal transmissions, and establishes penalties.

Every operator should be familiar with the contents of the Act, as it serves as the legal foundation for amateur radio—it’s the rulebook that protects the shared amateur radio spectrum from misuse.

B-001-003-004

🛑 Can inspectors or the Minister act without due process?

Inspectors and the Minister of Innovation, Science and Industry have the authority to enforce regulations—but that authority has boundaries. For example, it’s not correct to assume A radio inspector may enter a dwelling without the consent of the occupant and without a warrant. Canadian law protects the privacy of your home, even during investigations.

Similarly, the Minister may suspend an Amateur Radio Operator Certificate for cause, but this never occurs with no notice, or opportunity to make representations thereto. Due process is built into the enforcement process, ensuring fairness and accountability.

B-001-003-005, B-001-003-006

📡 Final Transmission

Canadian amateur radio operators are bound by strict legal limits that protect both the spectrum and the integrity of the service. Transmissions must remain within amateur bands, and the misuse of emergency signals or the sending of fraudulent messages is never permitted. Violations such as deliberate interference, false reporting, or fraudulent activity carry serious consequences, including fines of up to $5,000, imprisonment for up to one year, or both. At the same time, the Radiocommunication Act ensures that due process is respected: Innovation, Science and Economic Development Canada cannot take enforcement action without providing notice and an opportunity to respond, and inspectors may not enter a private home without consent and a warrant. By respecting these boundaries, operators safeguard their licences, maintain access to the bands, and uphold the trust that keeps amateur radio a reliable and responsible service.

B-001-004 – Operator Certificates, Applicability, Eligibility, Equivalents, and Recognition

Becoming a certified amateur radio operator in Canada isn’t just about passing an exam—it’s about understanding how qualifications work, what legal criteria apply, and how certifications from other services or countries might translate. This lesson breaks down the pathway to your first certificate, what qualifications unlock additional privileges, and how special cases like maritime certification or Morse code fit into the bigger picture.

You’ll also learn the important requirements every candidate must meet to earn their certificate and what it means to hold an Advanced qualification.

🎓 Who can get certified as a ham operator in Canada?

One of the great things about amateur radio is that There are no age limits for being granted an Amateur Radio Operator Certificate with Basic Qualification.

However, all candidates must Have a valid address in Canada. This ensures that operators can be properly licensed, reached for updates, and held accountable under Canadian regulations. As long as you’re located in Canada, you’re eligible to be certified!

B-001-004-001, B-001-004-007

📝 What do you need to pass to get your certificate?

Before you can receive your certificate, you must pass the standard written exam covering operating practices, regulations, and basic electronics. This is known as the Basic Qualification. It’s the foundation for all further privileges in amateur radio.

Additionally, if you already hold another recognized certificate—like the Canadian Radiocommunication Operator General Certificate Maritime (RGMC)—you may also be issued an Amateur Radio Operator Certificate without retaking the Basic exam. This recognition of equivalent training helps professionals from other radio services transition into amateur radio more easily.

B-001-004-002, B-001-004-003

🔁 How are additional qualifications earned?

Once you’ve earned your Basic Qualification, you’re free to explore further privileges through Advanced or Morse qualifications. These additional qualifications can be obtained in any order. You might choose to pursue your Morse Qualification first, or go straight into the Advanced exam.

B-001-004-004

✉️ What’s required for the Morse code endorsement?

Although Morse code is no longer required to obtain HF privileges. for most privileges, it’s still offered as an optional endorsement for those interested in CW (continuous wave) operation. To qualify, you must demonstrate both sending and receiving skills at a speed of 5 wpm (words per minute).

This relatively low threshold means that almost anyone can learn Morse with a bit of practice. In Canada, Morse code is no longer required to access HF bands (below 30 MHz). Instead, operators have two ways to qualify for HF privileges:

• Score 80% or higher on the Basic Qualification exam, or
• Pass the Advanced exam (or hold the older Morse code qualification)

This change, made in 2005, modernized access rules while still ensuring operators have a strong grasp of radio fundamentals before using the HF bands.

B-001-004-005

🚫 What does the Advanced Certificate not allow?

The Advanced Qualification unlocks powerful new privileges within the amateur radio service, including homebrewing transmitters, higher power levels, and operating repeaters. But that authorization applies to amateur service only.

If you’re wondering whether it lets you operate in other services—like aviation, marine, or commercial—the answer is simple: No other service. Holding an Advanced Amateur Radio Operator Certificate gives you extra rights in the amateur bands, but nothing beyond them.

B-001-004-006

📡 Final Transmission

Becoming a certified ham in Canada starts with the Basic Qualification, and There are no age limits for getting started—as long as you Have a valid address in Canada. If you already hold a Canadian Radiocommunication Operator General Certificate Maritime (RGMC), you may be eligible for direct certification. Additional endorsements like Morse Code can be earned in any order, and just 5 wpm gets you the code qualification. The Advanced Certificate gives you more power—but No other service privileges. Your journey, like your signal, starts with the right foundation.

📘 B-001-005 – Operation, Repair and Maintenance of Radio Apparatus on Behalf of Other Persons

In amateur radio, operators often collaborate, assist with station setup, or lend a hand in troubleshooting someone else’s gear. But there are limits to what you’re allowed to do on behalf of another person—even if you both hold certificates. This section explores when you can legally help, install, program, or repair equipment that doesn’t belong to you.

You’ll learn who must be certified, what kind of authorization is needed, and where regulatory lines are drawn. Understanding these conditions will help you avoid unintentionally violating licensing privileges.

🔧 Can you work on someone else’s equipment?

If you hold an Advanced Qualification, you’re permitted to build, repair, or modify amateur radio equipment—but only on behalf of another person who is authorized to operate it. In other words, you may do so if the other person holds an authorization for this apparatus. This ensures that all equipment remains tied to a licensed operator and is used within the bounds of amateur radio regulations.

The same rule applies to specialized modifications, like converting a land mobile transmitter for amateur use. Even if you have the technical skills, you can perform this work only if the other person holds an Amateur Radio Operator Certificate. These rules uphold accountability by preventing unauthorized modifications for unlicensed individuals.

B-001-005-001, B-001-005-002

🛠️ What must be true to install, repair, or place a transmitter in service?

Working on someone else’s amateur radio station—whether installing a new unit, running cables, tuning output, or placing a transmitter into service—means you must follow specific rules. Even with an Advanced Qualification, you’re not allowed to perform work that would let another person operate equipment beyond their certified privileges. The equipment must remain within the legal limits of the other person’s authorization.

Whether it’s a minor repair or a complete setup, the requirement is the same: both you and the other person must hold Amateur Radio Operator Certificates.

B-001-005-003, B-001-005-005, B-001-005-006

🧾 What if you have Morse and Basic qualifications?

Holding the Morse code qualification, along with your Basic certificate, extends your operating privileges in specific ways. One of these is the ability to assist with the installation of a complete amateur radio station for another licensed operator. But this privilege has limits…you can’t just set up a station for anyone.

You may perform the installation only if the other person is the holder of a valid Amateur Radio Operator Certificate. They must be legally authorized to operate the equipment once it’s installed. Without that certification on their end, even a qualified installer is not permitted to carry out the work.

B-001-005-004

📡 Final Transmission

Amateur radio has always carried a spirit of helping others, but assistance with equipment comes with firm boundaries. Operators may install, repair, or operate another person’s station only if that person holds the proper authorization, and reprogramming is permitted only when the individual possesses a valid Amateur Radio Operator Certificate. In nearly all cases, both parties must hold certificates to ensure accountability and compliance with Canadian regulations. Even when offering support, the responsibility for lawful operation remains with the authorized holder of the equipment. By knowing and respecting these rules, amateurs can lend a hand while still protecting the integrity of the service and the trust that keeps it accessible for all.

📘 B-001-006 –Operation of Radio Apparatus, Terms of Licence, Applicable Standards, Exempt Apparatus

Amateur radio is a licensed service governed by strict technical standards and operating rules. Whether you’re transmitting across town or tuning up a handheld VHF rig, you need to know where the legal lines are drawn. Some equipment may look flexible enough to be used across services—but staying within your authorized bands helps ensure safe, responsible, and interference-free communication.

This lesson explores who can use certain transmitters, when low-power devices need supervision, and why crossing frequency boundaries can have consequences.

🎚️ Who can operate low-power amateur transmitters?

Small transmitters, including those with power outputs of just a couple of watts, are still subject to regulation in Canada. Just because the power is low doesn’t mean the responsibilities are too. An amateur radio station with a maximum power output of 2 watts must be under the supervision of a person holding an Amateur Radio Operator Certificate and call sign.

This ensures that even very low-power operations follow proper procedures, identification rules, and don’t cause unintentional interference. Supervision is always required—even for beginners learning with simple gear.

B-001-006-001

📡 Who can you legally talk to on the air?

It’s important to know who you’re allowed to communicate with on amateur frequencies. You can’t just reach out to anyone with a radio; an amateur radio station may be used to communicate only with stations operated under similar authorizations.

That means licensed amateur operators—whether in Canada or internationally—who follow equivalent standards. Communicating with unauthorized, unlicensed, or commercial stations outside the amateur service may violate the terms of your certificate.

B-001-006-002

🔇 Can you amplify licence-exempt transmissions?

Some devices, such as certain short-range license-free transmitters (e.g., walkie-talkies, Wi-Fi devices), operate under licence exemptions. It may be tempting to boost their range using amateur gear. However, amateur radio operators are not permitted to use their equipment to enhance or extend the performance of licence-exempt transmitters. This is not permitted under any circumstances.

B-001-006-003

🚫 Can amateur equipment transmit outside amateur bands?

When is it permissible to transmit outside amateur radio bands using amateur equipment? Never, amateur radio equipment is not certified for operation outside amateur radio bands. Amateur radios are certified for use only within specific frequency bands. Even with modifications, they aren’t legally approved for transmitting on commercial, public safety, or other frequencies.

This restriction ensures safety, prevents harmful interference, and protects essential services that rely on clean, regulated spectrum use.

B-001-006-004

🛑 What are you not allowed to do with amateur radio equipment?

While amateur radio privileges are extensive, they don’t cross into other services such as use on aeronautical, marine or land mobile frequencies. These bands fall under entirely different licensing systems, each with its own technical and regulatory requirements.

Misusing amateur gear on these frequencies is both a technical and legal violation and can have enforcement consequences.

B-001-006-005

📻 When can dual-use radios be used legally?

Some VHF/UHF FM radios are capable of being programmed to operate in the land mobile service bands. This flexibility is useful, but only legal under specific conditions. If you want to use such a radio on land mobile frequencies, it must meet one key requirement: The radio is certified and licensed for use in the land mobile service.

Without this certification, using amateur gear on non-amateur frequencies—even if technically possible—is unlawful and can interfere with protected services like emergency or public works communications.

B-001-006-006

📡 Final Transmission

Every amateur transmission in Canada must take place under the direct supervision of a certified operator using a valid call sign, and communication is restricted to stations operating under similar authorizations. Relaying traffic to licence-exempt transmitters or operating alongside unauthorized services is strictly prohibited. Equally important is staying within the frequency ranges assigned to the amateur service. Amateur equipment is not certified for use outside these bands, and it cannot legally be employed on aeronautical, marine, or land mobile channels unless it has been separately certified and licensed for those services. By respecting these limits, operators not only remain compliant with federal regulations but also ensure that amateur radio maintains its integrity as a service dedicated to experimentation, communication, and public benefit.

📘 B-001-007 – Content Restrictions: Non-Superfluous, Profanity, Secret Code, Music, Non-Commercial

Amateur radio isn’t just about how we communicate—it’s also about what we’re allowed to say and share on the air. The amateur bands are not public broadcast services. They’re intended for personal, technical, and emergency use, with strict content guidelines. Certain types of communication—like business talk, music, encrypted codes, and public broadcasts—are off-limits entirely.

This lesson outlines the speech, topics, and signals that are permitted—and not permitted—under Industry Canada rules. It’s all about keeping the amateur service educational, non-commercial, and transparent.

📵 What topics and messages are strictly prohibited?

Amateur radio is not a replacement for commercial broadcasting or business communication. On-air discussions must be personal, technical, or hobby-related. Topics like Business planning are not allowed on nets or regular QSOs. In fact, In the amateur radio service, business communications are not permitted under any circumstance.

Similarly, broadcasts intended for the general public are strictly forbidden. These include pre-recorded shows, music transmissions, or anything resembling a commercial or entertainment radio service. The rules are clear: An amateur radio operator may never broadcast to the general public.

B-001-007-001, B-001-007-002, B-001-007-004, B-001-007-011

❌ What is not correct about amateur communications?

Some operators mistakenly believe that making occasional business-related comments—such as mentioning a sale or coordinating a delivery—is acceptable on the amateur bands. In reality, an amateur radio operator may conduct occasional business on the air is not allowed. Even brief references to commercial activity violate both the regulations and the non-commercial spirit of amateur radio.

Amateur radio exists for education, experimentation, and public service—not for business. Keeping the airwaves free of commercial use preserves fairness and ensures the hobby remains focused on learning and community.

B-001-007-003

🔐 Can you use secret codes, abbreviations, or encryption?

The amateur radio service is built on the principle of openness. Operators can use standard Q codes and abbreviations, but only if the meanings are widely understood. That’s why use of abbreviations if the signals or codes are not secret is permitted. Any communication that intentionally conceals meaning, even partially, goes against the purpose of amateur radio.

This same standard applies to digital modes. If you’re experimenting with new encoding techniques, you may only transmit them when it is published in the public domain. Even then, only when the encoding or cipher is not secret may a station transmit an encoded message. The expectation is that all amateur communications remain open to inspection by others in the amateur community. Above all, the transmission of a secret code by the operator of an amateur radio station is not permitted.

B-001-007-005, B-001-007-006, B-001-007-007, B-001-007-009, B-001-007-010

🎶 How do you prevent unintentional violations like retransmitting music?

Music and other non-amateur signals are not allowed on the amateur bands, even if they’re transmitted accidentally. Many violations occur when music plays in the background during a QSO—especially if a mic picks up a nearby radio or streaming device.

The simple fix…Turn down the volume of background audio. Be mindful of what your mic is capturing.

B-001-007-008

📡 Final Transmission

Amateur radio operators are bound by rules that keep the service non-commercial, open, and accessible to all. Business planning or transmissions intended for the general public are never permitted, and even unintentional violations—such as music being picked up by an open microphone—must be avoided. Broadcasting in any form is prohibited, as amateur communication is intended for two-way exchanges, not mass audiences. When using codes or signals, they must remain open and understandable, never secret or encrypted. Some operators may mistakenly assume that occasional business traffic is acceptable, but this is not the case. By keeping amateur radio free of commercial use, secrecy, and broadcasting, the service remains true to its purpose: education, experimentation, public service, and genuine connection across the airwaves.

📘 B-001-008 – Installation and Operating Restrictions: Number of Stations, Repeaters, Home-Built, Club Stations

Operating a station in Canada comes with technical privileges—but also specific qualifications for certain types of installations. Whether you’re running a simple home rig, setting up a repeater, or helping install a club station, your level of certification determines what you’re legally allowed to do.

This section focuses on who can build, install, or operate different types of amateur stations—including cross-band repeaters, remote transmitters, and non-commercial RF amplifiers. Knowing your limitations is part of operating responsibly.

📍 Where can you operate in Canada—and what about one-way signals?

Holders of a valid certificate aren’t limited by province or region. In fact, authorized amateurs may legally operate Anywhere in Canada. Whether you’re on a backcountry camping trip in BC or at a cottage in Nova Scotia, your callsign and privileges go with you.

However, not every kind of transmission is allowed in every context. One-way communications, for instance, are typically restricted—but there’s one exception. A Beacon station may transmit one-way communications for propagation testing and similar functions.

B-001-008-001, B-001-008-002

🧰 Can anyone assemble or install amateur gear?

Assembling gear isn’t the same as building from scratch. To legally put together professionally designed transmitter kits, an operator must hold at least the Basic qualification. This ensures the operator understands safety, component handling, and legal limitations.

But for more advanced installations—such as setting up a repeater, club station, or working with non-commercial gear—more knowledge is required. In these cases, operators must hold Basic and Advanced certification. These tasks involve higher technical responsibility and potential for broader RF exposure or interference, so the elevated qualification makes sense.

B-001-008-003, B-001-008-004, B-001-008-005, B-001-008-006

🔁 Can you operate a cross-band repeater or remote transmitter?

Cross-band repeaters are an important tool in amateur radio, allowing signals to be relayed across bands for greater coverage. These setups are relatively straightforward and require only a Basic qualification to operate. That means most hams can explore this feature as soon as they’re licensed.

However, controlling a transmitter remotely including adjusting frequency, output power, or emission mode is a more advanced procedure. The operator must hold Basic and Advanced qualifications to comply with the regulations,.

B-001-008-007, B-001-008-008

📡 Final Transmission

Every amateur operator must understand the privileges their certificate grants and ensure their activities match those qualifications. Once licensed, amateurs may operate anywhere in Canada, but only beacon stations are permitted to transmit one-way signals. Building and using simple kits is covered under the Basic certificate, while more complex work—such as installing repeaters, setting up club stations, or experimenting with untested RF equipment—requires both Basic and Advanced. Cross-band repeater operation falls within the scope of the Basic qualification, but remote operation of transmitters is reserved for those holding Basic with Advanced. By aligning operating practices with certificate privileges, amateurs protect the integrity of the service and demonstrate responsible use of the spectrum.

📘 B-001-009 – Participation in Communications by Visitors, Use of Station by Others

Operating your amateur radio station isn’t just about what you do—it’s about who else uses your equipment, how they’re supervised, and what your responsibilities are when guests or family members get on the mic. The control operator has legal responsibility while transmitting, and the station owner shares that responsibility in ensuring the station complies with regulations.

This section outlines who may operate, under what conditions, and how to stay compliant when others use your radio gear—whether they’re licensed or not.

👥 Who’s responsible for the station’s operation?

Running a station isn’t a solo responsibility. Legally, Both the control operator and the station owner are responsible for how the station is operated. That’s true whether you’re using your own station or someone else’s.

If you transmit from another station, it’s not just the owner’s responsibility. In that case, Both of you are jointly responsible. And if you own a station, You are responsible for the operation of the station in accordance with the regulations—even if someone else is using the gear under your permission.

B-001-009-001, B-001-009-002, B-001-009-003

🎙️ Who can be a control operator—and when are they required?

You can’t just let anyone operate your station unsupervised. The control operator must be Any qualified amateur radio operator chosen by the station owner. Whether it’s a club net, public demonstration, or just casual operation, someone qualified must be in control at all times.

A control operator must be present? Whenever the station is transmitting. That control operator must also be physically located At the station’s control point. There’s no “autopilot” mode in amateur radio—if it’s on the air, someone qualified must be in control.

B-001-009-004, B-001-009-005, B-001-009-006

👪 Can your friends or family use your station?

Friends or family members who are not licensed may only operate your station if you are right there supervising them. You must remain present and in control of the station at all times, and the responsibility for every transmission rests with you as the certificate holder.

The rules state clearly: They must hold suitable amateur radio qualifications before they are allowed to be control operators. If they aren’t licensed, they can still transmit—but only if When the person is under supervision, and in the presence of, a person holding appropriate qualifications. In short, unlicensed operators can only go on-air while directly observed by a certified amateur.

B-001-009-007, B-001-009-009

🆗 What can the station owner authorize?

As the station owner, you’re allowed to let others use your radio—but only under proper conditions. You may permit any person to operate the station under the supervision and in the presence of the holder of an Amateur Radio Operator Certificate. That means you’re responsible for ensuring they’re watched closely and that no violations occur on your watch.

Being a responsible station owner involves knowing these rules and following them anytime you invite someone to use your gear—whether they’re a curious friend or a new ham getting on the air for the first time.

B-001-009-008

📡 Final Transmission

Responsibility for a station is shared between the station owner and the control operator, and both are accountable for how the equipment is used. When operating someone else’s station, the designated control operator must be a qualified amateur chosen by the owner, and that operator must remain at the control point whenever the station is transmitting. Family members or guests may only use the station when they are directly supervised by a licensed operator who is physically present. As the owner, you may permit others to operate your equipment, but only under the supervision and in the presence of someone holding a valid Amateur Radio Operator Certificate.

📘 B-001-010 – Interference, Determination, Protection from Interference

In amateur radio, managing interference is a matter of both technical skill and regulatory responsibility. Knowing what causes interference, how it’s classified, and when to stop transmitting are essential parts of operating legally. Whether you’re sharing a band with primary users or testing a new setup, it’s your duty to avoid causing problems for others.

This lesson will help you understand the definitions and rules around interference, how band-sharing works, and what authority Industry Canada has to protect the airwaves.

📡 What is harmful interference—and when is it never allowed?

Any time your transmission affects another service’s ability to operate normally, it’s considered interference. When that interference is especially disruptive or persistent, it’s classified as Harmful interference. This includes blocking, degrading, or repeatedly interrupting communication signals.

There is zero tolerance for intentional interference on the amateur bands. Deliberate interference is never acceptable. No matter the reason or personal dispute, malicious jamming or intentional QRM violates regulations and could lead to fines and suspension.

B-001-010-001, B-001-010-002, B-001-010-005

🔄 Who gets priority—and what if multiple hams want the same frequency?

Amateur radio operators are allowed to use the frequency band only if they do not cause interference to primary users if amateur radio is listed as a “secondary user” of a frequency band. For example, hams often share bands with government, public safety, or commercial systems that always have priority.

When two amateurs want to use the same frequency they are required to work out the conflict cooperatively, as Both station operators have an equal right to operate on the frequency. That means—not by overpowering or jamming the other signal.

B-001-010-003, B-001-010-004

⚖️ What can the Minister do about interference?

If a station causes harmful interference, the Minister of Innovation, Science and Industry has the legal authority to intervene. This is taken seriously—especially if a station interferes with emergency or commercial communications.

In such cases, the Minister may Order the station’s operation to cease or change. This could include temporary shutdowns, frequency changes, or full suspension of operating privileges until the issue is resolved.

B-001-010-006

📶 Which bands require extra caution—and when are hams unprotected?

Some amateur bands are also shared with powerful or license-exempt devices, like industrial controllers and consumer electronics. In the 70 cm band, hams must avoid interfering with primary users operating in the 430.0 MHz to 450.0 MHz range. This means operating with care near sensitive services like military or public safety systems.

Conversely, amateur radio operations are not protected from interference in some ranges, including 902 MHz to 928 MHz. Unlicensed devices like cordless phones, baby monitors, and IoT equipment (physical objects that are connected to the internet and can collect, send, or receive data) may flood these bands, and hams have no legal protection from that interference.

B-001-010-007, B-001-010-008, B-001-010-010

🧪 When is it safe to conduct test transmissions?

Test transmissions are a routine part of station setup, tuning, and experimentation. However, operators must ensure that tests do not interfere with other users. You may only proceed When the transmission will not cause interference to stations in the amateur radio service or other services.

This includes checking SWR, adjusting power levels, or experimenting with modes. Always listen first and confirm the frequency is clear.

B-001-010-009

📡 Final Transmission

Amateur radio depends on operators sharing the spectrum responsibly and avoiding harmful interference. Any signal that disrupts communication is considered harmful, and intentional interference is never acceptable. To prevent problems, amateurs must monitor before transmitting and, if interference occurs, stop immediately to check equipment, reduce power, or change frequency. When two amateurs use the same channel, both have equal rights to operate, which requires courtesy and cooperation.

Extra care is needed in bands where amateur radio holds only secondary status. In these cases, operators may use the frequencies only so long as they do not interfere with primary services, and the Minister may order changes or cessation if problems arise. Special caution applies to ranges such as 430–450 MHz, shared with other services, and 902–928 MHz, where amateurs have no protection from interference. Even test transmissions are permitted only when they will not disrupt other services.

B-001-011 – Emergency Communications (Real or Simulated), Communication with Non-Amateur Stations

When disaster strikes, amateur radio operators often play a vital role. In emergency situations—whether real, simulated, or civil support—operators often help maintain communication between agencies, communities, and responders. That responsibility comes with clear rules and special permissions. It’s also a time when some normal restrictions are lifted to allow fast, effective response.

This section explores how amateur radio fits into emergency operations, including power limits, message handling, and when it’s legal to ‘bend’ the rules to save lives or assist with the communications component of disaster relief.

🆘 What can hams do in a distress or emergency situation?

During a real emergency, operators are permitted to use whatever tools are needed to get the message through. That includes using any frequency within amateur bands—even if you’re not normally authorized for it—if you hear a distress call. In such a case, you may respond and offer assistance.

An operator in distress may use any means of radiocommunication within the amateur bands to call for help. That means there’s No limitations on transmitter power, frequency privileges, or modes when life or safety is at stake. You may even interfere with another transmission—but only When your station is directly involved with a distress situation.

B-001-011-003, B-001-011-005, B-001-011-007, B-001-011-010

📡 Who can you communicate with—and when is broadcasting allowed?

Under normal conditions, amateur operators may engage in communications only with other amateur radio stations. Contact with commercial, government, or public service users is not allowed unless it occurs under officially recognized emergency protocols. Even in a disaster, operators must stay within the rules: using frequencies outside amateur radio bands is never permitted. All transmissions must take place on authorized amateur frequencies, regardless of the circumstances.

There is one exception to standard procedures during emergencies. If life or property is at immediate risk, radio communications required for the safety of life and property may be sent without concern for format or structure. This means you can abandon formal procedures and send clear, plain-language messages to get help fast. However, this does not extend to frequency use…you must still operate within your licensed amateur bands and follow all technical limits.

B-001-011-001, B-001-011-002, B-001-011-004

🛰️ When are special emergency permissions activated?

Hams may be called upon when commercial systems break down. During disasters or crises, amateur stations are permitted to transmit essential messages—but only When normal communication systems are overloaded, damaged or disrupted. This is the legal trigger for emergency amateur traffic.

During such times, operators can handle messages from public safety agencies, but only under structured arrangements. That includes During peace time, civil emergencies and exercises when practicing or assisting.

While amateur operators can send messages related to the safety of life and property during emergencies (see Section 48 of the Radiocommunication Regulations), they must still operate within the frequency bands authorized for their specific qualifications.

This means:

• A Basic-only operator without HF privileges is not legally permitted to transmit on HF, even during emergencies.
• Doing so would still be considered unauthorized operation under Canadian law.

✅ What you Can Do:

• Operate on VHF/UHF bands where you are licensed
• Relay emergency messages through repeaters or local nets
• Assist a licensed operator who has HF privileges, if present

B-001-011-006, B-001-011-009

🛑 What’s expected from operators not part of the emergency net?

One of the most helpful things an operator can do during a crisis is to give space. If you are not officially involved in an emergency net, your job is simple: Avoid needless transmissions on or near the net frequency. That includes tuning up, testing, or chatting nearby, all of which can block or degrade emergency communications.

Silence, in this case, is a form of participation. Listen first—and don’t transmit unless you’re part of the net or offering legitimate assistance.

B-001-011-008

📡 Emergency Operations Matrix – Canada

📡 Final Transmission

Amateur radio plays a vital role when regular communication systems fail. Operators are encouraged to assist in emergencies but must do so within the limits of their certification and authorized frequency bands. You may help relay or support communications, yet operating outside your assigned privileges is not permitted. Only a station in immediate distress—where life or property is at risk—may use any means or power level necessary to call for help.

Even during critical situations, communications must remain within the amateur bands and involve other licensed amateur stations only. Using non-amateur frequencies is never allowed. When disaster nets are activated, operators not directly involved should avoid transmitting on or near those frequencies to prevent congestion. Amateur emergency traffic is authorized during peacetime exercises and real emergencies alike, ensuring trained operators can assist effectively while maintaining professionalism, order, and compliance—no matter how urgent the situation.

📘 B-001-012 – Non-Remuneration, Privacy of Communications

Amateur radio is built on the principles of public service, shared learning, and mutual respect. That means the hobby is not to be used for personal profit or commercial gain. Likewise, operators are expected to uphold a high standard of privacy and integrity when it comes to the content they hear on the air.

In this section, you’ll learn about the rules surrounding compensation, message privacy, and when you’re allowed—or not allowed—to share the content of amateur transmissions.

💸 Can you get paid to relay messages or operate on the air?

The amateur bands are strictly non-commercial. Operators are not permitted to accept compensation for any activity that involves sending, receiving, or handling messages—even if it’s a favor or a third-party relay. That’s why No payment of any kind is allowed for third-party messages sent by amateur stations.

So, when is it ok to get paid?Never, it is expressly prohibited to demand or accept payment for exchanging messages. Whether it’s an emergency relay, a net check-in, or a DX report, your time on the air is always volunteer-based.

B-001-012-001, B-001-012-003

🔒 When can you share what you hear on the air?

Amateur radio operates on open frequencies, but that doesn’t mean everything you hear can be repeated. Operators must use discretion when discussing on-air content. You may only share what you hear if it was transmitted by an amateur radio station. This is because amateur radio is a public, non-confidential service, where exchanges between licensed amateurs are considered open communications by design.

However, there are clear legal limits. It becomes an offence to disclose private or non-broadcast transmissions when it is for the purpose of answering questions from a media organization. Even if a journalist asks about what was said on the air, you cannot share the content unless it was broadcast or officially authorized. Practicing discretion protects operators, preserves trust, and upholds the integrity of the amateur service.

B-001-012-002, B-001-012-004

Final Transmission

Amateur radio is a volunteer service built on learning, cooperation, and public goodwill. No payment or reward of any kind is permitted for operating, sending, or relaying messages, as the hobby must remain free from commercial influence. All amateur communications are conducted for education and public service, not for profit or personal gain. While the airwaves are open, operators still have a duty of discretion. Messages may be shared only when they are amateur transmissions intended for public communication. However, it is an offence to disclose the content of a non-broadcast message for media or journalistic purposes. These boundaries ensure that amateur radio stays true to its foundation—non-commercial, respectful, and dedicated to community service and experimentation.

📘 B-001-013 – Station Identification, Call Signs, Prefixes

Every amateur radio station must be clearly identified on the air. Your call sign is your legal signature and primary way to signal who you are, where you’re transmitting from, and that you’re operating within the rules. Canada has specific regulations about when, how, and in what language you identify your station.

This lesson covers the essential points about call signs, transmission intervals, and station identification rules—including how often to identify, which prefixes are Canadian, and the one exception when identification is not required.

🧾 What is a valid Canadian amateur call sign—and when must it be used?

A call sign not only identifies you legally, but it must also follow format conventions. In Canada, valid call signs typically begin with VA, VE, VO or VY. A good example would be VA3RAC, which follows both prefix and region assignment guidelines.

You must announce your call sign at the beginning and at the end of each contact, and repeat it at least every thirty minutes during longer exchanges. This timing ensures that anyone listening can confirm who is transmitting. The rules are the same for a test or a radio contact.

B-001-013-001, B-001-013-002, B-001-013-003, B-001-013-010, B-001-013-011

🗣️ When are call signs required during QSOs?

When two amateurs begin a QSO, Each station must transmit its own call sign. This confirms each operator’s identity before communications proceed. The same rule applies at the end of a contact: Each station must transmit its own call sign again to properly close the exchange.

Additionally, no station may transmit for longer than 30 minutes without identifying. This helps ensure ongoing accountability, especially during long nets or contests.

B-001-013-004, B-001-013-005, B-001-013-006

🔊 Are there any exceptions to identifying?

There is only one scenario in which you may transmit without identifying your station: Only to control a model craft. This exemption allows for control signals to be sent without repeatedly stating the call sign, which would be impractical for rapid telemetry or directional control.

For all other transmissions—including brief tests, pings, or tuning—you must still identify As The rules are the same for a test or a radio contact.

B-001-013-007, B-001-013-010

🌐 What language must be used when identifying?

When transmitting your call sign, you must use either of Canada’s two official languages. Identification is legal only in English or French. Using phonetics, abbreviations, or non-standard language doesn’t replace the requirement to use recognized, clearly spoken language when announcing your call sign.

This helps all listeners understand who is transmitting and ensures your signal is clearly traceable.

B-001-013-008

📡 Final Transmission

Station identification is at the heart of accountability in amateur radio. Every operator must clearly transmit their call sign at the beginning and end of each contact, and at least once every 30 minutes during longer exchanges. This simple practice promotes transparency, reinforces good operating habits, and helps keep the airwaves organized and professional. Call signs also represent a unique part of Canadian identity, with prefixes such as VA, VE, VO, and VY linking operators to their licensing region. By maintaining proper identification and courteous operating standards, amateurs meet both the spirit and the letter of the regulations—showing respect for their peers, their privileges, and the shared trust that keeps amateur radio strong.

📘 B-001-014 – Foreign Amateur Operation in Canada, Banned Countries, Third-Party Messages

International communication is one of the most rewarding aspects of amateur radio. But when operators cross borders—whether physically or over the airwaves—specific rules apply. Canada has agreements in place with many countries to allow visiting operators limited use of the airwaves, while also protecting the integrity of domestic operations. Equally important are the rules around third-party messages and which countries can or cannot participate in message exchanges.

This lesson covers what happens when foreign operators transmit in Canada, how third-party messages are handled, and which protocols are in place for global emergencies and disasters. It also explains when and how a Canadian amateur can legally communicate on behalf of someone else.

🛰️ Who can operate in Canada—and under what conditions?

The CEPT Agreement (Recommendation T/R 61-01) enables amateur radio operators from participating countries to operate in each other’s territories without obtaining additional licenses, provided they hold the appropriate qualifications. In Canada, this agreement is recognized by Innovation, Science and Economic Development Canada (ISED), allowing visiting European amateurs with CEPT licenses to operate with Advanced privileges. Conversely, Canadian amateurs with both Basic and Advanced qualifications can apply for a CEPT permit through Radio Amateurs of Canada (RAC) to operate in CEPT member countries.

Therefore, foreign amateur radio operators may transmit from Canadian soil, but only if Their country has an agreement with Canada and the amateur radio operator has obtained the appropriate permit. The CEPT agreement is one such path, allowing European hams to transmit with Advanced privileges while visiting Canada, as authorized by Innovation, Science and Economic Development Canada.

If a U.S. operator is on air in Canada, they must properly identify themselves. This includes stating Location by city and province at least once per contact, and, when using voice, also giving The Canadian call sign prefix for the geographic location of the station. These identifiers ensure that transmissions are legal and traceable within the Canadian regulatory framework.

B-001-014-002, B-001-014-005, B-001-014-009, B-001-014-010

📨 What about third-party communications?

Canada permits third-party message handling under specific circumstances. Operators may send a message on behalf of another person because Canada does not prohibit international communications on behalf of third parties. However,Only communications of a personal and non-commercial nature are allowed.

Even in emergencies, certain limits apply. International third-party communications during disasters are generally allowed, except when specifically prohibited by the foreign administration concerned. For example, if the destination country has opted out through the ITU, those communications must not occur. In some cases, The country has filed an objection to such communications with the International Telecommunication Union (ITU)  restricting third-party communications.

B-001-014-003, B-001-014-004, B-001-014-006, B-001-014-007

🧑‍🤝‍🧑 Who is a third party—and what happens in shared transmissions?

It’s important to know who qualifies as a third party. For example, if Both non-certified persons (such as a Canadian friend and a visiting operator’s friend) are engaged in communication using your station, both are considered third parties—and communication is not permitted unless regulations allow it.

If your certified friend is operating your station and a foreign station breaks in to address the unlicensed party, your job is to Continue monitoring the communications of your friend. You cannot allow unlicensed persons to handle transmissions independently.

Canadian stations can exchange third-party messages with any other amateur radio station—but only within the boundaries of the regulations already discussed.

B-001-014-001, B-001-014-008, B-001-014-011

🌍 Final Transmission

nternational operation brings added privilege—and greater responsibility. Foreign amateurs may transmit within Canada only if their home country maintains a formal reciprocal agreement or under CEPT recognition, and visiting U.S. operators must identify with both their call sign and the Canadian prefix. Third-party traffic is limited to personal, non-commercial messages and must always comply with established ITU agreements. These safeguards protect against interference and ensure that amateur radio remains a cooperative, self-regulated service across borders. By understanding and respecting these international requirements, Canadian operators strengthen global goodwill, maintain compliance with shared regulations, and demonstrate the professionalism that defines amateur radio both at home and abroad.

📘 B-001-015 – Frequency Bands and Qualification Requirements

In amateur radio, knowing which bands you can operate on—and under what qualifications—is essential for both compliance and effective operation. Frequency privileges in Canada are linked directly to the certification level you hold, and extra rules apply for operating below 30 MHz. Additionally, frequency ranges for specific HF bands must be memorized, especially for exam readiness and on-air operation.

This lesson will help you understand the link between exam performance and band access, the limits of control operator authority, and the specific band allocations across popular HF bands. You’ll also learn where you’re permitted to control model craft under Canadian regulations.

🪪 Operating Privileges and Certification

In amateur radio, it doesn’t matter who controls your equipment—it matters who holds the qualifications. If someone with more advanced certification operates your station using your callsign they’re still limited to only the privileges allowed by your qualifications. This ensures that certification levels are respected regardless of who is in control.

The same is true in reverse: if you are operating another person’s station and they have higher qualifications than you, you are still limited to Only the privileges allowed by your qualifications. The system is designed to keep operations consistent with the certification of the control operator, not the owner of the equipment.

B-001-015-001, B-001-015-002

📉 Accessing Bands Below 30 MHz

The lower-frequency amateur bands—below 30 MHz—are part of the coveted HF spectrum, and not everyone gets automatic access. Even after passing the Basic written examination, you must do more. Specifically, You must attain a mark of 80% on the Basic examination, or pass an Advanced or Morse code examination. These rules ensure operators on these bands have a higher level of training or experience.

Canadian amateurs who meet this standard can then operate across a wide range of bands, including some of the most popular international HF bands like 40 metres, 20 metres, and 10 metres.

B-001-015-003

🎮 Radio-Controlled Models

The operation of model aircraft, boats, or cars using amateur radio frequencies is strictly controlled. The rule is simple and straightforward: a licensed amateur may only use bands on all amateur radio bands above 30 MHz for this purpose. This ensures that model control operations stay within predictable, interference-safe regions of the spectrum.

This same frequency limit applies when determining which spectrum portions can legally support remote-control signals without overlapping with critical HF communication channels.

B-001-015-004, B-001-015-011

📡 Canadian HF Band Ranges

You’ll need to memorize the official frequency ranges of the major HF bands in Canada. Here’s a breakdown of the most common allocations:

• 160-metre band: 1.8 MHz to 2.0 MHz
• 80-metre band: 3.5 MHz to 4.0 MHz
• 40-metre band: 7. 0 MHz to 7.3 MHz
• 20-metre band: 14. 000 MHz to 14.350 MHz
• 15-metre band: 21.000 MHz to 21.450 MHz
• 10-metre band: 28.000 MHz to 29.700 MHz

These band edges are based on national regulations and international agreements and this knowledge is tested frequently in Basic Qualification exams.

B-001-015-005 to B-001-015-010

🧭 Final Transmission

Band privileges in Canada are tied directly to the qualifications you hold. Even if a higher-class operator uses your equipment, they cannot exceed the privileges of your licence. Access to HF frequencies below 30 MHz requires additional qualifications, demonstrated by achieving 80% or more on the Basic exam or by holding Advanced or Morse endorsements. Model control is limited to amateur bands above 30 MHz, while the HF allocations—from 160 through 10 metres—must be learned for both safe operation and exam success. By understanding these limits, amateurs operate responsibly while making the most of the spectrum their certification provides.

📘 B-001-016 – Maximum Bandwidth by Frequency Bands

📡 Understanding Bandwidth Limits

Bandwidth refers to the range of frequencies a radio signal occupies. In amateur radio, every transmission has a certain width depending on the mode and modulation being used—voice signals, for instance, use more bandwidth than Morse code. To avoid interference and ensure fair use of the radio spectrum, there are regulatory limits on the bandwidth of signals in specific frequency bands.

Understanding bandwidth restrictions is essential for operating legally and responsibly as a Canadian amateur radio operator. These rules not only maintain orderly use of the spectrum but also prevent one operator from unintentionally (or intentionally) interfering with another. Each amateur band has specific limits set out by Innovation, Science and Economic Development Canada (ISED), and exceeding these could result in unwanted interference or even penalties.

⚙️ Standard Limits Across the Bands

On some bands operators have more room to work with. For instance, the maximum authorized bandwidth on the 2-metre bands is 30 kHz, which accommodates FM voice transmissions and other wideband modes. The same bandwidth limit applies to the 50–54 MHz range, where 30 kHz is also allowed. These wider bandwidths make these bands suitable for high-fidelity voice or even digital operations.

On HF, however, the restrictions are tighter to conserve space for more operators. In the 28–29.7 MHz portion of the 10-metre band, the maximum transmission bandwidth drops to 20 kHz. Even more restrictive are bands between 7 MHz and 25 MHz—except for one special exception—where the maximum bandwidth is 6 kHz. These narrow limits are in place to prevent congestion and overlap between different stations and modes.

B-001-016-001 to B-001-016-005

🚫 Where Certain Modes Are Not Allowed

The 30-metre band, from 10.100 MHz to 10.150 MHz, is unique among HF bands. Due to its narrow slice of spectrum and its international shared use, it comes with both a bandwidth cap and a mode restriction. Here, the bandwidth must be less than 6 kHz, and single sideband (SSB) is not allowed. on 10.100 MHz to 10.150 MHz  This band is reserved primarily for digital and CW operations, making it unsuitable for wideband voice modes.

Other combinations are prohibited because they don’t match the technical or regulatory purposes of the band. For example, using  fast-scan television (ATV) on 145 MHz is not permitted, as this VHF segment is generally allocated for voice, digital, or repeater activity. Similarly, fast-scan television (ATV) on 14.23 MHz is also prohibited, since ATV modes require much more bandwidth than is allowed on HF.

B-001-016-006, B-001-016-007, B-001-016-009, B-001-016-010

🛑 Operating Near Band Edges

A critical skill for any ham is knowing where your signal begins and ends—especially near band edges. Each mode occupies space both above and below its center frequency. That means a signal placed too close to the edge of an amateur band may spill into adjacent non-amateur frequencies, potentially causing unintentional interference. To avoid this, operators must ensure that the entire occupied bandwidth falls within the amateur radio band.

This is especially important when using modes like SSB or digital, which can spread wider than expected. An operator transmitting SSB near the edge of a band may not realize that the upper or lower portion of their signal has crept out of bounds. Careful frequency selection—and sometimes switching to narrower modes like CW—can help avoid violations and maintain good amateur practice.

B-001-016-008

📡 Final Transmission

Bandwidth limits are in place to keep amateur radio signals clear, efficient, and fair. Wider allowances on VHF and UHF make room for voice and digital modes, while the narrower restrictions on HF bands preserve space for many operators to share. Special care is needed on bands with tighter rules or unique restrictions, and every operator must stay mindful of band edges to avoid spilling into adjacent services. By respecting these limits, amateurs help protect the spectrum and ensure smooth communication for all.

📘 B-001-017 – Restrictions on Capacity and Power Output by Qualifications

Transmitting power is one of the most closely regulated aspects of amateur radio. Power limits are enforced to reduce interference with other services and to promote efficient, responsible operation. Canadian amateur operators must understand how their level of qualification affects the power they are permitted to use—and how those limits vary depending on frequency, emission type, and operating mode.

This lesson explores the distinctions between Basic and Advanced privileges, explains how different power metrics (like PEP, ERP, DC input, and EIRP) are applied, and highlights where to verify compliance. By understanding these limits, operators can transmit confidently while staying within the legal and technical framework set by Innovation, Science and Economic Development Canada (ISED).

📡 Know Your Limits: The Power Guideline for All Operators

Regardless of qualification, Canadian amateurs are expected to operate with restraint. The universal rule is simple: use the minimumlegal legal  power necessary to communicate. This principle minimizes interference, reduces RF exposure, and keeps stations efficient.

Even when higher power is authorized, the best practice is to aim for reliable contact with the least possible output. Low power doesn’t mean weak signal—it means skillful, efficient operating.

B-001-017-001

📡 Peak Envelope Power (PEP): Maximums Based on Qualification and Frequency

For many operators, HF single sideband (SSB) is a primary mode. The maximum PEP depends on both the operator’s qualification and the band in use. With Advanced certification, an amateur may run up to 2250 watts PEP on SSB across most HF bands.

For Basic with Morse or Basic with Honours, the maximum is much lower on certain frequencies. On 3750 kHz, the maximum is 560 watts PEP on 3750 kHz. Similarly, on 7055 kHz, the limit is 560 watts PEP on 7055 kHz. These caps ensure signals stay strong enough for communication but not excessive enough to interfere with other users.

B-001-017-002, B-001-017-004, B-001-017-005

📡 Effective Radiated and DC Power: Understanding What’s Measured

It’s not just about how much power your rig can produce—it’s where the measurement applies. Operators must confirm that transmitter output stays within the limit at the output of the transmitter or amplifier, not after antenna or feedline gain.

On 60 metres, the limit is expressed as ERP. Advanced operators may use up to 100 watts ERP, referenced to a half-wave dipole. On other HF bands, DC input power is also regulated. For Advanced, the maximum allowed is 1000 watts DC input power to the final RF stage. These rules account for differences in measurement standards while ensuring that output power remains safe and compliant.

B-001-017-003, B-001-017-006, B-001-017-007

📡 Basic Qualification? Mind the Lower Caps

Operators holding only the Basic certificate must follow lower limits. The maximum allowed is 250 watts DC input power to the transmitter’s final stage. In addition, when using emissions other than SSB—such as CW, AM, FM, or digital—the maximum is 190 watts carrier power. These rules limit continuous-duty signals, which can otherwise strain equipment or create interference issues.

B-001-017-009, B-001-017-010

📡 Special Considerations: LF and MF Bands

On the 630-metre and 2200-metre bands, antennas are much shorter than the wavelength, making them inefficient radiators. Because of this, regulators express power limits in equivalent isotropically radiated power (EIRP), which combines transmitter power with antenna performance. To remain within those limits, operators must account for antenna gain, since even small amounts of directional gain increase total radiated power.

When designing or tuning antennas on these low-frequency bands, it’s essential to calculate effective gain accurately to avoid exceeding authorized EIRP levels. Properly understanding this relationship allows operators to stay compliant while achieving the best possible signal from limited antenna systems.

B-001-017-008

🧭 Final Transmission

Power limits keep amateur radio both safe and orderly. The rule for all operators is restraint—always use the minimum power needed to make the contact. Higher privileges with Advanced certification allow for more power on HF and VHF, while Basic qualifications come with stricter caps. Special metrics like ERP, DC input, and EIRP make sure power is measured fairly across different bands and modes. By knowing these distinctions and applying them carefully, amateurs protect the spectrum, respect their fellow operators, and demonstrate true operating skill.

📘 B-001-018 – Unmodulated Carriers and Retransmission

In amateur radio, efficient use of spectrum and responsible signal handling are foundational principles. Retransmission and carrier testing are essential tools for extending coverage and ensuring proper equipment function, but they must be used in a controlled and legal manner. The rules governing these activities are especially important for operators with a Basic Qualification, who have specific frequency limits for repeater use and testing.

This lesson reviews what constitutes a repeater station, when unmodulated carriers are allowed, and which parts of the HF spectrum Basic holders can access for repeater communication. Understanding these points ensures every operator respects their privileges and avoids unintentional interference or regulatory violations.

📡 What Is a Repeater and What Does It Do?

A repeater station is one of the most valuable assets in amateur radio, enabling extended communication beyond line-of-sight. These automated stations receive a signal on one frequency and retransmit it on another, effectively boosting its range. According to Canadian regulations a repeater station is an amateur radio station that automatically retransmits the signals of other stations. This function is crucial in emergency communications and daily VHF/UHF operations.

Repeaters help operators in mobile or remote locations maintain contact with nets and communities. Because they operate without manual control, their configuration and use are tightly regulated to prevent interference and overuse. Proper identification, time-outs, and licensing considerations all apply.

📡 Using Unmodulated Carriers Legally

There are moments when an operator needs to test their transmitter without modulation—perhaps to check SWR, verify signal strength, or conduct antenna diagnostics. However, these carrier signals must not be used casually, and if a dummy load is not used, an unmodulated carrier may be transmitted only for brief tests on frequencies below 30 MHz.

Misuse of unmodulated carriers, such as transmitting for extended periods can disrupt communications and be interpreted as intentional interference. Always log or note your test activity and keep transmissions brief and necessary and identify your station Callsign prior to testing.

📡 Repeater Access for Basic Qualification Holders

Operators holding only the Basic Qualification must pay attention to band-specific restrictions, especially when accessing repeater outputs. HF repeater operation is permitted, but only on clearly defined frequencies. The lowest output frequency of repeaters that holders of a Basic Qualification are allowed to use is 29.500 MHz. This gives access to the 10-metre band under certain conditions.

The lowest output frequency band segment for repeaters accessible to Basic-only operators is 29.500 MHz to 29.700 MHz. This is a small but important slice of the radio spectrum, and operating outside of it with a Basic certification violates ISED regulations.

🧭 Final Transmission

Rules on unmodulated carriers and retransmission protect both the amateur bands and other services sharing nearby spectrum. Carriers may only be used briefly for testing, and repeaters operate within strict definitions to ensure consistency. Access to certain HF segments is limited, and Basic operators must stay within the narrow 29.500–29.700 MHz window. By respecting these rules, amateurs maintain efficient use of the spectrum and avoid unnecessary interference.
