Short answer: Canada has no single GPS-tracking law, and that surprises almost everyone who asks. The Criminal Code provision people find first, section 492.1, is a warrant power for police, not a rule for private conduct. What governs everyone else is a patchwork: criminal harassment if tracking forms part of a pattern that makes someone fear for their safety, mischief arguments about interfering with someone’s property, the privacy tort of intrusion upon seclusion, privacy statutes on the commercial side, and employment law for fleet vehicles. The practical rules that fall out of that patchwork: tracking a vehicle you solely own is generally defensible, tracking a partner’s or a jointly owned vehicle is a legal and personal minefield, employers can track their own fleets for legitimate purposes with disclosure, and a private investigator’s licence adds no tracking power whatsoever.
There is no single GPS law, and the one everyone finds does not apply to them
Search for “GPS tracking law Canada” and the first thing you hit is section 492.1 of the Criminal Code, which speaks of tracking devices, vehicles and covert installation. Read it closely, though, and it is a provision about warrants: a justice may authorize “a peace officer or a public officer” to obtain tracking data, including by covertly installing and removing a device. It exists because the Supreme Court recognized decades ago, in R. v. Wise, that state tracking of a vehicle engages the Charter’s protection against unreasonable search, so Parliament built a judicial-authorization regime for it.
What section 492.1 does not do is regulate private citizens, and neither does any other single statute. There is no offence called “unlawful GPS tracking” in Canada. Instead, whether a private person’s tracking is lawful depends on whose property the device touches, whose movements are captured, in what relationship, and for what purpose. That is why the honest answer changes completely across the four situations below, and why so much confident advice on this topic is wrong in both directions.
Tracking your own vehicle
The clearest case: a vehicle you solely own is your property, and installing a GPS unit on it is generally lawful. Fleet security devices, stolen-vehicle recovery systems and the tracker a parent puts in the car they own and lend to a new driver all live here. Two boundaries still apply.
First, ownership of the vehicle is not ownership of everyone in it. If the practical purpose of “tracking my own car” is monitoring a specific adult who drives it, the situations below start to apply regardless of whose name is on the ownership, because the harassment and privacy analysis looks at what you are doing to a person, not just whose asset carries the device.
Second, joint ownership is not sole ownership. The family car that both partners own is the other owner’s property too, and that distinction carries most of the weight in the next section.
Tracking a spouse or partner
This is the question behind most of the calls we get on this topic, and the site already gives the short version in our guide to infidelity investigations: we do not place trackers, and you should not either. Here is the fuller legal picture.
- Criminal harassment is the sharpest edge. Section 264 of the Criminal Code prohibits, among other things, repeatedly following a person and besetting or watching the places they live and work, where the conduct causes them to reasonably fear for their safety. Covert tracking that feeds a pattern of showing up, monitoring and confronting can land squarely in that territory, and the offence carries up to ten years. In a relationship already marked by control, tracking is not a neutral fact-finding tool; it is part of the pattern our article on coercive control describes.
- The mischief argument. Attaching a device to a vehicle you do not solely own involves dealing with someone else’s property, and section 430 of the Criminal Code makes wilful interference with property an offence. We flag this consistently as a risk rather than a certainty, because there is no reported decision squarely holding that a spousal GPS tracker is mischief; but “no case yet” is thin protection, and the surrounding exposure does not depend on it.
- The privacy tort is real and fits exactly. Ontario recognizes intrusion upon seclusion, from Jones v. Tsige: intentional or reckless invasion of private affairs that a reasonable person would find highly offensive. Months of covert location data on a partner is close to a textbook fact pattern, and it supports damages without proof of financial loss.
- Family court will not thank you. Even where tracking evidence exists, courts expect matrimonial disputes to run on lawful disclosure and admissible evidence, and self-help surveillance of a spouse reliably damages the credibility of the person who did it. Our legal reference on surveillance evidence in family court covers what actually helps.
If the underlying question is real, the answer is not a device in a wheel well. It is a conversation with a family lawyer, and where facts genuinely need documenting, lawful covert surveillance by a licensed investigator, which observes public movement without touching anyone’s property.
Employers and fleet vehicles
Employer GPS is the one area with a developed body of guidance, and it points to a workable middle: employers may track their own vehicles for legitimate operational purposes, with honesty about it.
The federal Privacy Commissioner’s foundational finding, PIPEDA Case Summary #2006-351, examined GPS in a telecommunications company’s work vehicles. The Commissioner accepted purposes like dispatch, asset protection and safety, while cautioning against “function creep”: the slide from managing vehicles into continuously managing people through the data, without safeguards. For federally regulated employers, that PIPEDA lens, purpose, proportionality and openness under section 5(3), still governs directly. For provincially regulated Ontario employers, PIPEDA generally does not reach employee data, a distinction we cover in pre-employment due diligence, but the same principles arrive through other doors: arbitration and wrongful-dismissal case law weigh proportionality, and dishonest or covert monitoring undermines the very evidence employers hope to use.
Ontario also added a disclosure rule: under section 41.1.1 of the Employment Standards Act, an employer with 25 or more employees on January 1 must have a written electronic monitoring policy stating whether it monitors electronically, how, in what circumstances, and for what purposes, with a copy to every employee. The section creates a transparency obligation rather than a new right to sue over monitoring itself, but it means silent fleet tracking is no longer a lawful posture for employers of that size.
The practical employer rules: track vehicles you own; disclose it in policy; tie the data to stated operational purposes; and treat personal or off-duty use of the vehicle as the sensitive zone it is. An employer who follows those lines has little to fear, and one investigating suspected misuse of company assets should pair the data with advice, and with the procedural-fairness discipline in our guide to internal theft investigations.
Where private investigators stand in Ontario and Canada
Now the section this article exists for, because the industry does not always say it plainly.
A private investigator’s licence confers no tracking power. The PSISA licenses us to conduct investigations; it grants no police powers, no property-interference powers, and no exemption from any of the law above. The Criminal Code’s tracking-warrant regime in section 492.1 authorizes peace officers and public officers, on judicial authorization; a licensed investigator is neither. There is no warrant an Ontario PI can apply for, no statutory carve-out, and no client instruction that changes any of that. PIPEDA’s investigative exception, paragraph 7(1)(b), addresses when personal information may be collected without consent; it says nothing about attaching hardware to property, and it is not a licence to do so.
So when an investigator offers to “slap a tracker on the subject’s car,” they are proposing to do with your money what you should not do yourself, and they are attaching the exposure to your file. The evidence would arrive with a taint that invites exclusion, undermines every other piece of the investigation, and hands opposing counsel a gift. It is the same category of offer as bugging a room, which our recording-conversations reference covers: the fact that a device is cheap and available does not make its use lawful.
What a licensed investigator in Ontario can lawfully do:
- Document movement the lawful way. Physical surveillance from public vantage points, the craft this site’s Art of Surveillance series describes in detail, establishes where a subject goes and when, admissibly, without touching anyone’s property.
- Work with a client’s own assets. Where a client solely owns a vehicle or fleet, advising on lawful telematics, retrieving and analyzing data the client is entitled to, and building it into an investigation is legitimate work, subject to the employment-law framework above when employees drive those vehicles.
- Find the trackers. The mirror image of this whole topic: our TSCM and counter-surveillance work locates devices placed on clients’ vehicles and in their spaces, and documents them properly as evidence.
That is the whole of it. Our published position across this site has been consistent and it stays consistent here: we rely on lawful physical surveillance, we do not place tracking devices on vehicles our clients do not own, and any operator who shrugs at that line should make you wonder what else they shrug at. For how to check any Ontario investigator’s licence before hiring them, see our verification guide.
If you think you are being tracked
The other side of the question deserves its own answer, because finding a device, or fearing one, is increasingly common.
- Do not destroy what you find. A tracker is evidence: of who placed it, when, and of a pattern. Photograph it in place before anything else, and note the date, location and circumstances.
- Think before confronting. If the likely placer is a partner or ex-partner and the situation carries any safety dimension, confrontation can escalate risk. Speak to police, a lawyer, or a victim-services resource first; where tracking is part of a fear-inducing pattern, section 264 makes it a police matter.
- Get the vehicle and your spaces checked properly. Consumer detectors miss more than they find, for reasons our TSCM explainer walks through. A professional sweep confirms what is there, and produces documentation you can actually use.
- Mind your accounts as well as your bumper. Much modern “tracking” is an ex-partner’s access to shared accounts, family-location features and connected-car apps rather than hardware. Changing credentials and auditing device access is part of the same response; our personal digital-security guidance is a starting point.
What to do next
If you are weighing whether to track someone: the lawful path almost never involves a device, and a free consultation costs nothing before a mistake that could cost a great deal. If you suspect you are being tracked, a TSCM sweep answers the question properly. And if your matter needs someone’s movements documented in a way a court will accept, that is what licensed covert surveillance is for.
Frequently asked questions
Is it legal to put a GPS tracker on someone else’s car in Canada?
On a vehicle you do not own, treat the answer as no. There is no statute that permits it, and the conduct can engage criminal harassment where it forms part of a pattern that makes someone fear for their safety, potential mischief arguments about interference with property, and civil liability for intrusion upon seclusion. Tracking a vehicle you solely own is a different situation.
Can I track the family car if my name is on the ownership?
Joint ownership is the trap. A jointly owned vehicle is the other owner’s property too, and using your access to it to covertly monitor a partner invites the same harassment, mischief and privacy-tort exposure, plus a very poor reception in family court. Courts expect disputes to run on disclosure and evidence gathered lawfully, not on self-help surveillance of a spouse.
Can my employer track the vehicle I drive for work?
An employer can generally use GPS on vehicles it owns for legitimate purposes such as dispatch, safety and asset protection. The federal Privacy Commissioner has accepted those purposes while warning against using the data to manage employee performance without safeguards. In Ontario, employers with 25 or more employees must also have a written electronic monitoring policy under the Employment Standards Act that discloses how and why they monitor.
Can a private investigator put a GPS tracker on a subject’s car in Ontario?
A licence is not a permission slip for this. The PSISA gives investigators no police powers, and the Criminal Code’s tracking-warrant provision applies to peace officers and public officers, not licensed investigators. Attaching a device to a vehicle the client does not own is conduct we treat as off the table; the lawful alternative is physical surveillance, which documents movement without touching anyone’s property.
What should I do if I find a GPS tracker on my car?
Do not destroy it, and think before confronting anyone. Photograph it in place, note the date and location, and preserve it as potential evidence. If the tracking is part of a pattern that makes you fear for your safety, that is a police matter. A professional TSCM sweep can confirm whether the vehicle or your other spaces carry anything else.
