Is it legal to record a conversation in Canada?

In short: Yes — in Canada you can legally record a conversation you are part of, without telling anyone. Under the Criminal Code's one-party consent rule, the consent of any single participant is enough (s. 183.1). But secretly recording a conversation you are not part of is a crime under s. 184, punishable by up to five years in prison. And "legal to make" does not mean "useful in court" — judges still decide whether a recording gets admitted as evidence. CourtStairs answers questions like these in plain language, with citations to the actual section of the Code.

Most everyday law in Canada is provincial, so answers usually change at the border between Ontario and Quebec or Alberta and BC. Recording law is the unusual exception: the core rule comes from the federal Criminal Code, so the "can I record this?" answer is the same coast to coast. What varies by province is what happens after — how a recording can be used as evidence, and whether it exposes you to a privacy lawsuit.

What is the one-party consent rule in Canada?

Canada is a one-party consent country: you may record any conversation you are part of, because your own consent is enough. The starting point is s. 184(1) of the Criminal Code, which makes it an offence to wilfully intercept a private communication using a recording or listening device. On its own, that sounds like recording is banned. The key is the exception in s. 184(2)(a): it is not an offence if you have the consent, express or implied, of the originator of the communication or the person intended to receive it.

Section 183.1 then makes the rule crisp: where a private communication has more than one party, "a consent to the interception thereof by any one of those persons is sufficient consent." In plain terms: if you are one of the people in the conversation, you are that consenting party. You can record it, and you do not need to warn or ask anyone else.

This is different from "two-party" or "all-party" consent jurisdictions you may have read about in some U.S. states. Canada is a one-party consent country nationwide.

When is recording a conversation a crime?

Recording becomes a crime the moment you record a private conversation you are not part of — that is illegal interception under s. 184, punishable by up to five years in prison. Whether a recording is legal turns on one question: are you in the conversation?

So leaving a phone recording on the kitchen table to capture what your roommates say while you are out is not covered by one-party consent — you are not a participant in that conversation. But recording your own call with a contractor, your own meeting with a manager, or your own doorstep exchange with a neighbour is fine.

Do the police need a warrant to record with one party's consent?

Yes — usually. Even when one participant consents, police normally need prior judicial authorization under s. 184.2 before they can rely on that consent to record. There is one important twist. When the police (or someone acting for them, like an informer) want to rely on one participant's consent to record, they generally cannot just do it. Section 184.2 requires them to get judicial authorization first: a judge must be satisfied there are reasonable grounds to believe an offence has been or will be committed, that a party has consented, and that the recording will yield information about the offence. That authorization can last up to 60 days.

This matters to ordinary people mainly as reassurance: the state's power to record is fenced in by a judge, even though a private individual recording their own conversation is not.

What does one-party consent NOT protect you from?

One-party consent only answers the criminal interception question — it does not shield you from voyeurism charges, privacy lawsuits, business privacy duties, or workplace discipline. One-party consent answers the interception question. It does not give you a free pass on everything else.

1. Voyeurism (s. 162)Even in your own conversation, secretly recording someone who is nude or expects sexual privacy — a bedroom, bathroom, or change room — is a separate crime carrying up to five years.
2. Business call recordingOrganizations that record customer calls have privacy duties under PIPEDA (or provincial privacy laws in BC, Alberta, and Quebec), which usually means telling callers and limiting how the recording is used.
3. Provincial privacy tortsRecording or publishing what others say — especially people you are not talking to — can trigger civil claims. BC, Saskatchewan, Manitoba, and Newfoundland and Labrador have statutory privacy torts; Ontario recognizes "intrusion upon seclusion."
4. Workplace and professional rulesA recording can be legal yet still breach an employment policy, a collective agreement, or a professional code — with consequences up to termination even if no crime occurred.

Can I use a secret recording as evidence in court?

Sometimes — but not automatically. A recording that was legal to make must still clear ordinary evidence rules, and family courts in particular are openly hostile to secret recordings. This is where people are most often surprised. A recording that was legal to make is not automatically admissible in court. Two separate hurdles remain.

First, ordinary evidence rules. To be admitted, a recording generally must be relevant to a real issue, authentic (genuinely what it claims to be, unedited), and reliable, with the speakers identifiable. A judge weighs its value against any unfairness before letting it in.

Second, judicial attitude — which varies by the type of case and, in practice, by province. Family courts are notably hostile to secret recordings of a spouse or co-parent. Judges across the country have described the practice as "odious" and something to be discouraged, and may admit a covert recording only where its usefulness clearly outweighs the harm of encouraging that behaviour. Even when admitted, a secret recording can make the person who made it look like the high-conflict party.

If your dispute is heading to court anyway, it also helps to know the clock: see our guides to limitation periods for suing, by province and small claims court limits in Canada.

Quick reference

Do recording laws differ by province in Canada?

No — the criminal recording rule is federal and identical nationwide, but what happens after you record does vary by province. Recording law breaks the usual pattern. Criminal law is federal, so the one-party consent rule in s. 183.1 and the interception offence in s. 184 apply identically everywhere in Canada — there is no "province with stricter recording rules." What changes at the provincial line is the fallout: how family, employment, and civil courts treat a recording, and which privacy torts let someone sue you for making or sharing it. So the safe habit is a two-step check: Am I in the conversation? (the federal criminal question), and What will happen if I use or share this? (the provincial and contextual question).

Where CourtStairs fits

CourtStairs answers everyday questions like "can I record this call?" or "will a court accept my recording?" in plain language, and points you to the primary source — the actual Criminal Code section — so you can read the rule yourself before you act on it.

This post is general information, not legal advice. Criminal recording rules are federal, but how a recording can be used and whether it exposes you to a civil claim vary by province and by context, and the law changes over time. Confirm the current rule against the official statute or a lawyer before relying on it.
