Police Stops and Detention in Ontario

What is this right?
Sections 9 and 10 protect you from arbitrary detention. The two cases that set the rules are R. v. Mann (2004) and R. v. Grant (2009).
Investigative detention lets police briefly hold you on reasonable suspicion tied to a specific crime — not a hunch, and not a general sense that something's off. Detention itself starts the moment your liberty is meaningfully suspended, by physical force or by psychological pressure.
Random vehicle stops are constitutional under R. v. Ladouceur — police can pull you over to check licence, sobriety, and roadworthiness without a specific suspicion.
Carding — random street checks — is the most controversial part of policing in Canada. Provinces from Ontario to BC have rolled out rules tightening when officers can stop and question people without an investigative basis. The Supreme Court's R. v. Le (2019) made clear that the social and racial context of policing factors into the s. 9 analysis.
When does it apply?
The rights apply to everyone in Canada.
- Investigative detention requires reasonable suspicion linked to a specific crime.
- Traffic stops don't need specific suspicion — road safety is enough.
- Carding — if you're not detained, you generally don't have to stop or answer.
What to Do If Police in Canada Stop or Detain You
The single most important question to ask in any unclear police interaction:
- Ask: "Am I being detained, or am I free to go?"
- If free to go, leave calmly. Don't run.
- If detained, ask why and ask for a lawyer.
- On a traffic stop, hand over licence, registration, and insurance.
What should you NOT do?
- Don't walk off when told you're detained. That gets you a fresh charge.
- Don't assume a stop authorises a vehicle search. It doesn't.
- Don't lie about your identity when you're legally required to give it.
- Don't confuse a casual chat with detention. The question — "am I free to go?" — clarifies it instantly.
How Ontario differs from federal law
Ontario has specific rules about when and how police can stop and detain people, shaped by both provincial legislation and landmark Ontario court decisions.
- Under the Highway Traffic Act, police can stop any motor vehicle to check for a valid licence, insurance, and sobriety. You must provide your driver's licence, vehicle registration, and proof of insurance (section 33).
- Ontario banned carding (random street checks) through O. Reg. 58/16 under the Police Services Act. Police cannot arbitrarily stop people and demand identification without a lawful reason. If you are stopped on foot and not detained, you do not have to identify yourself.
- An investigative detention (briefly stopping someone based on reasonable suspicion) must be brief and proportionate. The Ontario Court of Appeal has set boundaries on how long a detention can last and what police can do during it.
- If police detain you, they must tell you why and inform you of your right to counsel. A detention triggers full Charter protections under section 10.
- Police cannot use racial profiling as a basis for stops. The Ontario Human Rights Commission has issued policy guidance on racial profiling, and the HRTO can order remedies for profiling-based stops.
Additional Steps in Ontario
If you are stopped on the street, you can ask: "Am I being detained or am I free to go?" If you are being detained, ask why and request a lawyer. If you are not being detained, you may leave. For a traffic stop, comply with the requirement to produce your licence and insurance, but you do not need to answer other questions. If you believe you were profiled, file a complaint with the Office of the Independent Police Review Director (OIPRD) at oiprd.on.ca or call 1-844-264-7732.
