Is One-Party Consent Recording Legal in Canada? [2026]

Under Canada’s Criminal Code, RSC 1985, c C-46, s 183.1, recording a conversation you are part of is legal across every province without telling the other person — your own consent is enough. What is illegal is recording a private communication you are not a party to. Provincial statutes in BC, Ontario, and Quebec add civil obligations on top.

What is one-party consent under Canadian law

One-party consent, in Canadian law, means that any participant in a private communication may lawfully record it without the knowledge or consent of the other participants. The rule derives from Criminal Code s 183.1, which states: “a consent to the interception thereof by any one of those persons is sufficient consent for the purposes of any provision of this Part.” The communicating party who holds the recorder is that consenting party.

The threshold question is whether the communication is “private” in the first place. The Criminal Code s 183 defines “private communication” as any oral communication or telecommunication made under circumstances in which it is reasonable for the originator to expect that it will not be intercepted by anyone other than the intended recipient. This expectation-based definition means that conversations in genuinely public spaces — where interception is predictable — may not qualify as “private communications” at all, and the s 183.1 exception may be unnecessary to invoke.

The same section defines “intercept” to include “listen to, record or acquire a communication or acquire the substance, meaning or purport thereof.” This is broad enough to cover smartphone audio recordings, call-recording apps, and any electronic means of capturing a conversation — including VoIP and encrypted messaging platforms.

This post covers the federal statute, the two leading Supreme Court decisions, provincial overlays, and what the rules mean for investigators and the clients they serve. For context on employee monitoring more broadly, see our companion analysis of employee monitoring statistics, or our practical primer on whether surveillance is legal in the spousal cheating context, where the same one-party-consent framework applies.

Criminal Code section 184: the interception prohibition

The prohibition that one-party consent carves through is found at Criminal Code, RSC 1985, c C-46, s 184(1), which makes it a hybrid offence, punishable on indictment by up to five years’ imprisonment, for any person who “by means of any electro-magnetic, acoustic, mechanical or other device, knowingly intercepts a private communication.” There is no minimum sentence.

Section 184(2) carves out five saving exceptions. The most practically important is s 184(2)(a): the prohibition does not apply where there is “consent to intercept, express or implied, of the originator of the private communication or of the person intended by the originator thereof to receive it.” This is the statutory doorway through which one-party consent recordings pass — when you are the originator or intended recipient and you consent to your own recording, you satisfy s 184(2)(a) and the prohibition does not apply.

The Code also creates two flanking offences that operate independently of whether the original interception was lawful. Disclosing or using a recording obtained without lawful consent is separately criminalised at s 193(1), which carries up to two years’ imprisonment on indictment for knowingly using, disclosing, or revealing the existence of a private communication that was intercepted without authorization. Possessing a device “knowing that its design renders it primarily useful for surreptitious interception of private communications” is a separate offence under s 191, punishable by up to two years on indictment, with exceptions for licensed peace officers and persons authorized by the Minister of Public Safety.

Section 183.1: the one-party consent exception

• What s 183.1 says verbatim. The section reads in full: “Where a private communication is originated by more than one person or is intended by the originator thereof to be received by more than one person, a consent to the interception thereof by any one of those persons is sufficient consent for the purposes of any provision of this Part.” It was added by 1993, c 40, s 2 in direct response to R. v. Duarte (see below).

• Available to private citizens, not just police. The exception is unqualified by the class of person invoking it. A person recording their own conversation with a boss, a landlord, or a contractor is exercising the same statutory right. The moment the recorder is not a party to the conversation being recorded, however, the exception disappears and s 184(1) applies in full.

• State agents face an additional step. When police officers or informers wish to use the one-party consent exception, Criminal Code s 184.2 requires judicial pre-authorization. The judge must be satisfied that there are reasonable grounds to believe an offence has been or will be committed, and that information about that offence will be obtained through the interception. Authorization is valid for a maximum of 60 days.

• Emergency interceptions have a narrow safety-valve. Criminal Code s 184.4 allows a peace officer to intercept a private communication without prior authorization when: (a) the urgency of the situation is such that authorization could not, with reasonable diligence, be obtained; (b) the interception is immediately necessary to prevent an offence that would cause serious harm to any person or property; and (c) the originator or intended recipient of the communication is the person likely to commit or be victimized by that harm. This section was originally enacted in 1993 and substantively amended in 2013 by the Protecting Canadians from Online Crime Act.

How Canadian courts have interpreted the rule: R. v. Duarte and R. v. Jarvis

The two Supreme Court decisions that define the boundaries of lawful recording in Canada are R. v. Duarte, 1990 CanLII 150 (SCC), [1990] 1 SCR 30 and R. v. Jarvis, 2019 SCC 10. They address different questions but together frame the constitutional and criminal limits on recording.

In R. v. Duarte, the Supreme Court held that police interception of private communications by participant surveillance — recording a conversation with the consent of one party only, without judicial authorization — violated s 8 of the Canadian Charter of Rights and Freedoms. The Court found that the state’s use of a co-conversationalist as an instrument of surveillance left “all the conditions under which conversations are intercepted to the sole discretion of the police” and was therefore unreasonable. The decision did not prohibit one-party consent recording by private citizens — it prohibited the state from conducting it without prior judicial oversight. Parliament’s legislative response was the 1993 amendment that added s 184.2, requiring judicial pre-authorization whenever state agents wish to conduct participant surveillance. The rule for private citizens — who have no state power to abuse — was left unaffected.

R. v. Jarvis involved a high school teacher who had secretly recorded female students using a hidden camera concealed in a pen. A unanimous Supreme Court convicted the teacher under Criminal Code s 162(1), the voyeurism provision, and established a contextual nine-factor test for when a person has a “reasonable expectation of privacy”: relevant factors include the location, the nature of the conduct, whether consent was given, the relationship between the parties, and the purpose of the recording. The Court rejected the argument that being in a semi-public space such as a school hallway eliminates a person’s privacy expectation, holding that “technology may make it easier to violate someone’s privacy, but that doesn’t mean a person should have to accept it.” The Court also noted that video recordings warrant distinct treatment from mere observation because they “capture more detail, [are] permanent, and can be easily viewed, edited, and shared.”

The combined effect of Duarte and Jarvis is that the one-party consent exception under s 183.1 remains robust for private citizens recording their own conversations — but audio recording in semi-public spaces for a sexual purpose, and any recording by state agents without authorization, can still constitute a criminal offence under the voyeurism or interception provisions.

Provincial privacy overlays: Ontario, BC, and Quebec

• Ontario — electronic monitoring transparency. Ontario added Part XI.1 to the Employment Standards Act, 2000 on April 11, 2022, requiring any employer with 25 or more employees in Ontario on January 1 of a year to maintain a written policy on electronic monitoring of employees. Employers who employed 25 or more workers on January 1, 2022 had until October 11, 2022 to comply. The policy must state whether monitoring occurs and, if so, describe how, in what circumstances, and for what purposes. Critically, the Part XI.1 requirement does not prohibit employers from monitoring electronically — it requires transparency. Failing to maintain a written policy exposes the employer to enforcement action under the ESA.

• British Columbia — tort of privacy. BC’s Privacy Act, RSBC 1996, c 373, s 1 establishes a tort of privacy: “It is a tort, actionable without proof of damage, for a person, wilfully and without a claim of right, to violate the privacy of another.” Section 1(4) specifies that “privacy may be violated by eavesdropping or surveillance, whether or not accomplished by trespass.” A victim does not need to prove financial harm — the violation itself is the cause of action. A recording that is lawful under Criminal Code s 183.1 may nonetheless attract civil liability in BC if the court finds the recording was a wilful violation of privacy without a legitimate claim of right.

• Quebec — express consent and Law 25. Quebec’s Act Respecting the Protection of Personal Information in the Private Sector, CQLR c P-39.1, as amended by Law 25 (2021, c 25), requires that consent to the collection of personal information be “clear, free and informed and be given for specific purposes” (s 14). For sensitive personal information — defined by its medical, biometric, or otherwise intimate nature, or by contextual factors creating a high level of reasonable expectation of privacy — express consent is required. The final tranche of Law 25 amendments entered effect January 1, 2024. Law 25 also added s 8.1, requiring organizations using technology that identifies, locates, or profiles individuals to inform those individuals and to disclose means to activate or deactivate identification, location, and profiling functions. This provision directly affects employers and investigators who use GPS tracking, AI-enhanced video analysis, or call-recording platforms on individuals in Quebec.

When a legal recording becomes inadmissible or gets you fired

• Charter s 24(2) exclusion in criminal proceedings. A recording that is lawfully made under one-party consent may still be excluded from evidence in criminal proceedings if its admission would “bring the administration of justice into disrepute” under Charter s 24(2). The Supreme Court’s three-factor test from R. v. Grant, set out on Justice Canada’s Charterpedia, requires courts to weigh: (1) the seriousness of the Charter-infringing conduct; (2) the impact on the accused’s Charter-protected interests; and (3) society’s interest in adjudication on the merits. Note that s 24(2) applies only in proceedings involving state actors — labour and civil admissibility is governed by separate evidentiary rules.

• Ontario labour arbitrations — divided practice. In Ontario labour arbitrations, a secret workplace recording may be admitted or rejected depending on the arbitrator’s approach: some arbitrators apply a common-law relevance test under which anything relevant is admissible; others apply a labour-relations test and exclude recordings that would erode the ongoing collective bargaining relationship. There is no uniform rule, and both outcomes are regularly reported in Ontario arbitration practice.

• Just-cause dismissal risk. An employee who secretly records a workplace conversation may be dismissed for cause even though the recording itself was lawful under Criminal Code s 183.1. Ontario courts and labour arbitrators assess whether the recording so seriously eroded the trust relationship between employer and employee that dismissal is justified. Employers must show the specific circumstances — not merely the act of secret recording — warranted termination.

• PIPEDA proportionality: the OPC’s three-condition test. The Office of the Privacy Commissioner’s guidance on covert video surveillance (last revised 2015) requires organizations contemplating covert surveillance to satisfy three cumulative conditions before collecting: (1) the purpose must be one a reasonable person would consider appropriate in the circumstances; (2) the collection must be effective — directly connected to legitimate business goals; and (3) it must be proportionate, with no less intrusive alternative available. A “mere suspicion” is not sufficient. In PIPEDA Findings #2021-008, the OPC found a trucking company’s always-on audio recording of drivers, including during off-duty hours and sleep, violated PIPEDA s 5(3) because a reasonable person would not consider the surveillance appropriate in the circumstances.

• Non-consensual distribution of intimate images. Even where recording a private encounter was consensual or lawful, distributing that recording is a separate offence. Criminal Code s 162.1, added in 2014 (c 31, s 3), prohibits knowingly publishing, distributing, transmitting, or selling an intimate image when the person depicted did not consent to that distribution. The penalty is up to five years on indictment.

What one-party consent means for investigators and their clients

The one-party consent rule is operationally significant for licensed private investigators in ways that differ from how it applies to the general public — and the limits are stricter than many clients expect.

A licensed private investigator in Ontario is subject to the Private Security and Investigative Services Act, 2005, SO 2005, c 34 (PSISA), which requires licensing and compliance with a Code of Conduct. An investigator who intercepts a private communication without being a participant — for example, placing a hidden device in a room to capture conversations between third parties — violates Criminal Code s 184(1) regardless of their PSISA licence. Licensing does not grant recording powers beyond what the Criminal Code permits to any private citizen.

When an investigator is a direct participant in a conversation — conducting a telephone interview with a subject, or meeting a source in person — they may lawfully record that exchange under Criminal Code s 183.1 without disclosing the recording. Evidence so obtained is lawfully collected and is generally admissible in Ontario civil proceedings.

For investigations in Quebec, the federal Criminal Code baseline coexists with Quebec’s Act Respecting the Protection of Personal Information in the Private Sector, CQLR c P-39.1, as amended by Law 25. Investigators collecting personal information about Quebec residents must treat audio recordings as “personal information” subject to purpose-limitation, consent, and transparency obligations — over and above the federal one-party consent rule. Where the two regimes conflict, the stronger protection governs; the Office of the Privacy Commissioner has acknowledged P-39.1 as substantially similar legislation that displaces federal PIPEDA in Quebec.

The OPC’s 2023 workplace privacy guidance reaffirms that employers under federal privacy law must treat employee monitoring as a personal-information collection subject to PIPEDA’s accountability, transparency, and limited-collection principles. Investigators retained by federally-regulated employers to conduct workplace investigations must structure their engagement to meet these requirements.

As Ontario-licensed investigators, we decline work that would require placing a recording device in a space where we are not a participant — full stop. The Criminal Code’s participant-only exception is bright-line, and the practical question we ask before any audio collection is simple: is our investigator the one having the conversation? If yes, the recording is lawful under s 183.1. If no, it requires a wiretap authorization we cannot obtain as private actors.
