Canadian law grants no special surveillance rights to spouses. Whether monitoring a current or former intimate partner is lawful turns on three federal statutes — the Criminal Code, RSC 1985, c C-46, PIPEDA, SC 2000, c 5, and Ontario’s PSISA, SO 2005, c 34 — none of which create a spousal exception. As licensed PIs, we decline work that would expose a client to criminal liability — the lines are not where people expect.
What are the limits of spousal surveillance under Canadian law
“Spousal surveillance” is not a defined term in Canadian law. It describes any act of observing, recording, tracking, or monitoring a current or former intimate partner. Whether such conduct is lawful turns on three questions under federal statute, each of which the sections below address in sequence.
(1) Does the method of collection interfere with the subject’s reasonable expectation of privacy? (2) Does the purpose and extent of collection satisfy PIPEDA, SC 2000, c 5, s 5’s proportionality requirement? (3) Does the conduct — particularly repeated watching or following — cross into Criminal Code s. 264 (criminal harassment)?
Section 5 of PIPEDA requires that any collection of personal information be limited to purposes that a reasonable person would consider appropriate. The Act’s s. 4(2)(b) carves out a personal or domestic purposes exemption for individuals — meaning a person who monitors a spouse entirely for personal reasons and shares the data with no one may fall outside PIPEDA’s reach. That exemption disappears the moment a third party, such as a private investigation firm, is engaged, because the firm is an organization conducting commercial activity and is therefore fully subject to PIPEDA.
When a PI firm is retained, the Office of the Privacy Commissioner’s 2015 Guidance on Covert Video Surveillance sets out a three-condition test for when covert collection is acceptable under PIPEDA: (1) there must be a demonstrable, evidentiary need — not mere suspicion — for the collection; (2) the information must be clearly related to a legitimate purpose; and (3) the privacy loss must be proportional to the benefit gained, meaning less invasive alternatives must have been exhausted first.
One subject the Criminal Code addresses in detail — audio interception of private communications under ss. 183–184.2 — is covered in full in the companion post on one-party consent recording in Canada. This post focuses on GPS tracking, video surveillance, and the PI-practitioner framework for family court proceedings.

GPS tracking: when it is lawful and when it is criminal
The lawfulness of GPS tracking a spouse’s vehicle turns on a simple but frequently misunderstood threshold: vehicle ownership and consent.
When GPS tracking is lawful:
- The person deploying the device is the sole registered owner of the vehicle and has not ceded control of it to their spouse by agreement. Under this ownership scenario, installing a tracker does not interfere with another person’s lawful use of property under Criminal Code s. 430.
- A licensed PI is retained by a client who is the sole registered owner, and the engagement is documented with current vehicle registration confirming sole ownership — bringing the tracker installation within PIPEDA’s legitimate purpose framework.
- Law enforcement is conducting tracking under a judicial warrant obtained pursuant to Criminal Code s. 492.1, which authorises peace officers and public officers to install tracking devices on reasonable grounds.
When GPS tracking is criminal or legally risky:
- The vehicle is jointly owned or owned by the spouse alone, and no consent has been given. Placing a tracker on such a vehicle without consent can constitute criminal mischief under Criminal Code s. 430(1), which prohibits wilfully obstructing, interrupting, or interfering with the lawful use, enjoyment, or operation of property. Conviction on indictment carries a maximum of 10 years imprisonment; summary conviction carries up to two years less a day and/or a $5,000 fine.
- A private individual — including a spouse — attempts to rely on Criminal Code s. 492.1 as authority for installing a tracker. That section authorises only peace officers and public officers acting under warrant. Private persons are not authorised by that section. A warrant under s. 492.1 lasts up to 60 days for standard offences and up to one year for organized crime or terrorism offences — neither scenario applies to a private individual tracking a spouse.
- A jointly titled matrimonial vehicle is tracked without the co-owner’s consent, even where the tracking party believes they have a right to do so. Joint ownership does not confer the right to interfere unilaterally with the co-owner’s use and enjoyment of the property.
Video surveillance from public and semi-public spaces
Criminal Code s. 162(1) (voyeurism) prohibits surreptitiously observing or making a visual recording of a person in circumstances where that person has a reasonable expectation of privacy. Three alternative triggers apply: (a) the person is in a place where nudity or sexual activity could reasonably be expected; (b) the person is nude and the recording targets that state; or (c) the observation or recording is made for a sexual purpose. Conviction on indictment carries up to five years imprisonment.
The critical principle for spousal surveillance is that being visible in a public or semi-public place does not automatically eliminate a reasonable expectation of privacy. In R. v. Jarvis, 2019 SCC 10 (decided February 14, 2019), the Supreme Court of Canada unanimously held that a teacher who used a hidden pen camera to film female students’ cleavage in classrooms and school hallways committed voyeurism under s. 162, even though the school was a semi-public space where students were routinely observed by others. The Court found that the entire context of the recording must be assessed — not merely whether the subject was visible to others at the moment of recording.
This principle applies directly to spousal surveillance. Covert recording of a spouse in a shared home, workplace, or other semi-public location does not become lawful simply because that person might be observed by others in the same space. A recording made for a sexual purpose, or targeting intimate body parts, can constitute voyeurism even in a genuinely public setting.
Covert video recording in a private space where a reasonable expectation of privacy is unambiguous — a shared bedroom, bathroom, or home office — is criminal under s. 162 regardless of the relationship between the parties.
How Canadian courts assess reasonable expectation of privacy: the R. v. Jarvis factors
In R. v. Jarvis, 2019 SCC 10, the Supreme Court of Canada articulated nine non-exhaustive contextual factors for determining whether a person has a reasonable expectation of privacy for the purposes of Criminal Code s. 162(1):
- The location of the person when observed or recorded.
- Whether the conduct was observation or recording.
- Whether the person was aware of or consented to potential observation.
- The manner in which the observation or recording was done.
- The subject matter or content of the observation or recording.
- Any rules, regulations, or policies governing the observation or recording.
- The relationship between the observer and the person observed.
- The purpose for which the observation or recording was done.
- The personal attributes of the person observed or recorded.
No single factor is determinative. Courts apply these factors holistically — which means surveillance that might appear lawful on the basis of location alone (a public street or park) can still violate privacy where other factors weigh heavily against the recorder. Factor 7 (the relationship between observer and observed) and factor 8 (purpose) are particularly significant in spousal surveillance cases, where an intimate relationship creates heightened privacy expectations and where the purpose is frequently to gather evidence for domestic proceedings.
Criminal harassment and stalking: when surveillance crosses the line
Criminal Code s. 264 defines criminal harassment as engaging in prohibited conduct, without lawful authority, knowing or being reckless as to whether the other person is harassed, where that conduct causes the victim to reasonably fear for their safety or that of someone known to them. The four prohibited categories under s. 264(2) are:
(1) Repeatedly following the person from place to place. (2) Repeatedly communicating with the person, directly or indirectly. (3) Besetting or watching a dwelling-house, workplace, or other place where the person resides, works, carries on business, or happens to be. (4) Engaging in threatening conduct directed at the person or their family.
Conviction on indictment carries a maximum of 10 years imprisonment. Where the offence is committed in contravention of a prohibition order or recognizance, that prior order is an aggravating circumstance at sentencing.
Spousal surveillance crosses into criminal harassment under s. 264 when it involves “besetting or watching” a place where the spouse resides, works, or carries on business — category (3) above — or when it involves repeatedly following the spouse — category (1). The statute does not provide a spousal exemption, and a genuine belief that one is entitled to watch a partner is not a defence once the conduct causes the victim to reasonably fear for their safety.
The Crown must generally prove that the prohibited conduct was repeated or sustained to a degree that would cause a reasonable person in the victim’s circumstances to fear for their safety — a single incident of following typically does not suffice. However, a single episode of besetting (actively blocking or surrounding a location) may, depending on circumstances, satisfy the threshold.
Courts have also recognized that the civil tort of intrusion upon seclusion, established in Jones v. Tsige, 2012 ONCA 32, provides an additional civil remedy for unlawful spousal surveillance, independent of any Criminal Code exposure. The three elements are: (1) the defendant intentionally or recklessly invaded the plaintiff’s private affairs without lawful justification; (2) the invaded matter was one in which the plaintiff had a reasonable expectation of privacy; (3) a reasonable person would regard the invasion as highly offensive, causing distress, humiliation, or anguish. Damages are capped at $20,000 absent exceptional circumstances, and no proof of economic harm is required.
Surveillance method by lawfulness: a quick-reference grid
| Method | Vehicle ownership / consent | Location | Lawful? | Criminal risk |
|---|---|---|---|---|
| GPS tracker on spouse’s car | Sole registered owner + consent | Any | Yes | None if deployed properly |
| GPS tracker on spouse’s car | Joint owner, no consent | Any | No | Criminal mischief s. 430; possible s. 264 |
| GPS tracker on spouse’s car | Neither owner nor consent | Any | No | Criminal mischief s. 430; possible s. 264 |
| Video recording in public space | N/A | Public street, park | Yes (no sexual purpose, no nudity) | None |
| Covert video recording | N/A | Shared bedroom / bathroom | No | Voyeurism s. 162; possible s. 264 |
| Surveillance by licensed PI | Client sole vehicle owner | Any | Yes (with proper engagement) | None if PSISA/PIPEDA compliant |
| Surveillance by licensed PI | Client lacks sole ownership | Shared private property | No | PI faces mischief / PSISA breach; client faces s. 430 |
| Repeated watching / following | N/A | Any | No if repeated + causes fear | Criminal harassment s. 264 |

What a licensed private investigator can and cannot do
What a licensed Ontario PI can do:
- Conduct overt observation of a subject in public places and document movements in locations where no reasonable expectation of privacy exists.
- Take photographs and video recordings of a subject in public settings, provided the recording is not for a sexual purpose and is not directed at intimate body parts.
- Install a GPS tracker on a vehicle where the client is the sole registered owner and current registration confirming sole ownership has been obtained — keeping the engagement within the PIPEDA proportionality framework and outside the s. 430 mischief risk zone.
- Compile surveillance reports documenting a subject’s activities, locations, and associations in a form that can be verified under oath at a subsequent hearing.
Under the Private Security and Investigative Services Act, 2005, SO 2005, c 34 and Ontario Regulation 363/07 (Code of Conduct), every licensed PI in Ontario must comply with all federal, provincial, and municipal laws; respect the privacy of others by treating all information received as confidential; refrain from behaviour that is prohibited or not authorised by law; and treat all persons equally without discrimination.
What a licensed Ontario PI cannot do:
- Install a GPS tracker on a vehicle the client does not solely own — even a jointly titled matrimonial vehicle — without the co-owner’s consent. Doing so exposes both the investigator and the client to criminal mischief charges under Criminal Code s. 430 and risks disqualification from PI licensing under PSISA.
- Enter private property without the occupant’s permission (Trespass to Property Act).
- Intercept private communications without lawful authority under Criminal Code ss. 183–184.2.
- Compel anyone to speak with them or provide information — a licensed PI is not a peace officer and holds no powers of arrest beyond those available to ordinary citizens.
- Conduct surveillance in a manner that constitutes criminal harassment under Criminal Code s. 264.
When a PI firm is retained to conduct spousal surveillance, it must satisfy the OPC’s three-condition PIPEDA test — demonstrable need, legitimate purpose, and proportionality — confirmed in PIPEDA Case Summary #2008-392. The personal or domestic purposes exemption in PIPEDA s. 4(2)(b) does not extend to PI firms acting as commercial organizations.
Admissibility of surveillance evidence in family court
The framework for admissibility of surveillance evidence at trial was established by the Ontario Court of Appeal in Iannarella v. Corbett, 2015 ONCA 110. The Court held that surveillance video must satisfy a three-part test before admission: (1) accuracy — the recording must truly represent the facts; (2) fairness — there must be no intention to mislead; (3) verification on oath — a person capable of doing so, typically the investigator who conducted the surveillance, must verify the recording under oath. The Court required a voir dire before surveillance evidence is admitted, at which the videographer may be examined. Even where these three conditions are met, the trial judge must further find that the probative value of the evidence outweighs its prejudicial effect.
Licensed PI surveillance evidence is more likely to be admitted than DIY surveillance in family proceedings for four practical reasons. First, a licensed PI can appear as a witness and verify the evidence under oath, directly satisfying the Iannarella verification requirement. Second, a licensed PI documents the chain of custody of recordings, reducing the grounds for a chain-of-custody exclusion application. Third, surveillance conducted within PSISA and PIPEDA constraints limits the grounds on which the opposing party can argue the evidence was illegally obtained. Fourth, a licensed PI provides independent, professional testimony rather than self-interested evidence from the surveilling spouse, which courts treat differently in credibility assessments.
Family courts retain discretion to exclude evidence gathered through unlawful surveillance even when it might otherwise be probative. Unlawfully obtained surveillance also creates litigation risk: courts may draw adverse inferences from improper conduct and may award costs against the party who gathered evidence in breach of privacy law.

What this means if you are considering spousal surveillance
Before engaging any surveillance of a spouse, three legal realities govern the decision. First, the legality of every method depends on specific facts — vehicle ownership, location, purpose, and duration — that a lawyer can assess but that a general online search cannot resolve for a particular situation. Second, evidence gathered unlawfully is at risk of exclusion in family court and may result in adverse cost orders against the party who gathered it, potentially converting a tactical advantage into a liability. Third, surveillance that amounts to criminal harassment under Criminal Code s. 264 can result in criminal charges regardless of what the person believes they are entitled to do — the statute does not recognize a spousal exception or a self-help justification.
A licensed private investigator operating under PSISA and within PIPEDA’s three-condition framework provides the clearest path to evidence that will withstand scrutiny in family court proceedings. The combination of professional documentation, chain-of-custody records, and the ability to appear as an independent witness satisfies the Iannarella requirements in a way that DIY surveillance rarely does.
