Police questioning can move fast. A conversation on the street can become a detention. A detention can become an arrest. What you say in those few minutes can end up as evidence against you.
The Canadian Charter of Rights and Freedoms protects you through that process, but it does not work the way American television suggests. This guide explains what your rights actually mean in Ontario, and what they do not mean.
Disclaimer: This article reflects general legal information based on Ontario and Canadian law. It is not legal advice. Every case is unique, and you should consult a qualified criminal defence lawyer about your specific situation.
These are three different legal events, and different rights attach to each one.
Police can approach you in public and ask general questions. If you are free to walk away and choose to speak anyway, the detention-specific protections in sections 9 and 10 of the Charter have generally not been triggered. Voluntary contact does not eliminate your other Charter protections. For example, section 8 may still be engaged if police conduct amounts to a search or seizure affecting a reasonable expectation of privacy.
Detention happens when your freedom of movement is significantly restrained, physically or psychologically, by police authority, even without handcuffs. The Supreme Court's test in R. v. Grant asks whether a reasonable person in your circumstances would believe they had no real choice but to comply, looking at how the encounter started and how police behaved. Once you are detained, sections 9 and 10 of the Charter apply immediately.
Arrest happens when police physically take you into custody, or use clear words of arrest that you submit to. An arrest must be authorized by law. For a warrantless arrest, the required grounds depend on the particular arrest power police are relying on. Section 495(1) of the Criminal Code includes several routes, including reasonable grounds to believe a person committed or is about to commit an indictable offence, finding a person committing a criminal offence, or reasonable grounds to believe an arrest warrant is in force. For specified offences, section 495(2) further limits when police may arrest without a warrant. In R. v. Carignan, 2025 SCC 43, the Supreme Court confirmed that those limits are mandatory and that an arrest contrary to them is unlawful. Arrest also triggers section 10 of the Charter, including the right to know why and the right to counsel without delay.

| Detained | Arrested | Charged | |
|---|---|---|---|
| What it means | Liberty is significantly restrained, physically or psychologically. No handcuffs required. | Police have exercised an arrest power that has to meet a legal threshold. | You have become an accused person. You are not necessarily in custody. |
| Right to know why | Yes, under section 10(a) | Yes, under section 10(a) | Section 11(a) adds the right to know the specific offence without unreasonable delay |
| Right to counsel | Yes, right away | Yes | Not a new trigger on its own, but a charged person should still get counsel |
| Search power | No automatic search power; a pat-down is permitted only where police have reasonable grounds to believe there is a genuine safety risk | Search connected to the arrest may apply, within limits | A charge alone creates no independent search power |
Section 10(a) of the Charter gives everyone who is arrested or detained the right to be informed promptly of the reasons. Police have to give a real explanation. They do not have to recite an exact Criminal Code section or reveal their entire case, but the explanation has to be meaningful enough for you to understand why your liberty is being restricted.
Section 10(b) gives you the right to retain and instruct counsel without delay, and to be told about that right. Police have to give you a real, private opportunity to reach a lawyer, including access to duty counsel through Legal Aid if you do not have one, and generally must hold off questioning or attempting to elicit incriminating evidence from you until that opportunity has been provided. Say it clearly: "I want to speak to a lawyer."
Once you have had a real chance to speak with a lawyer, police can generally keep questioning you. In R. v. Sinclair, the Supreme Court confirmed that an adult does not have a general right to have that lawyer physically present in the room, the right is to consult counsel, not to have counsel present during the interview. A further opportunity to consult counsel can still be required if your circumstances materially change, for example if the investigation shifts to a more serious offence or a new procedure is introduced that changes what you are actually facing.
You are not required to explain yourself, and you can continue to say so for as long as the interview goes on. Police may keep asking, but that does not change your right. Exercising your right to silence is not itself an admission of guilt, and any statement the Crown wants to use still has to be proven voluntary.
Arrest gives police some search powers, but not unlimited ones. A search after arrest generally has to be lawful, connected to a real purpose such as safety, preserving evidence, or locating evidence tied to the arrest, and reasonable in scope.
In R. v. Fearon, the Supreme Court held that a cell-phone search incident to arrest is not automatic. A warrantless cell-phone search incident to arrest requires a lawful arrest, a valid law-enforcement purpose connected to the arrest, a search tailored in nature and scope to that purpose, and detailed police notes about what was searched and why. Where the purpose is to discover evidence, a prompt phone search is justified only where the investigation would be stymied or significantly hampered without it.
A strip search does not automatically follow from an arrest. Under R. v. Golden, it requires specific grounds and a proper protocol beyond the fact of a lawful arrest.
Your IP address attracts Charter privacy protection too. In R. v. Bykovets, the Supreme Court held that a police request for an IP address is itself a search under section 8, meaning police generally need lawful authority, ordinarily judicial authorization, to obtain one from a third party.
A home receives the strongest search protection under the Charter. Police generally need prior judicial authorization to arrest someone inside a dwelling, subject to narrow exceptions such as hot pursuit or a genuine emergency. This is a technical area where the specific facts matter, so it is worth getting advice quickly if police have entered or want to enter your home.
There is no general law requiring you to identify yourself just because police ask. There is also no rule that you can never be required to. It depends on the legal authority police are exercising and whether a specific law creates an identification obligation, such as when you are driving.
A police traffic stop is a detention, so section 10(b) is engaged. However, the Supreme Court has held that the opportunity to consult counsel can be temporarily delayed while lawful immediate roadside sobriety screening is carried out. A driver generally cannot delay a lawful immediate roadside breath demand to call counsel first, and refusing without a reasonable excuse is itself an offence. Once the immediate roadside screening stage ends and detention continues for further investigation, the ordinary section 10(b) right to consult counsel generally has to be implemented before further investigative steps, subject to any other lawful exception. Our First-Offence DUI in Ontario guide explains roadside screening, breath demands, licence consequences, and what happens after a first impaired-driving charge in more detail.
If the roadside investigation results in an impaired-driving charge, Sanctuary Lawyers provides dedicated DUI Defence representation for impaired driving, over-80, refusal, and drug-impaired driving allegations.

For many arrests without a warrant, police are expected to release you as soon as practicable, by summons, appearance notice, or undertaking, unless there is a specific reason under the Criminal Code to keep you in custody.
If police do not release you, the law requires that you be brought before a justice without unreasonable delay, and within 24 hours if a justice is available. Our Ontario Bail Hearing Explained guide explains what happens at the hearing, how release plans and sureties can matter, and what to expect in court.
Once you are charged, section 11 of the Charter adds a further set of rights: to know the specific offence without unreasonable delay, the presumption of innocence, and the right not to be denied reasonable bail without just cause. You can be charged and not in custody, and you can be arrested before any formal charge is laid.
If police do not release you, the law requires that you be brought before a justice without unreasonable delay, and within 24 hours if a justice is available. If you need representation at this stage, our Bail Hearings service explains how Sanctuary Lawyers prepares release plans and represents clients seeking release.
A Charter breach does not automatically mean the charge disappears. Under section 24(2), a court can exclude evidence obtained through a breach, but only if admitting it would bring the administration of justice into disrepute. Courts weigh how serious the breach was, how it affected your Charter-protected interests, and society's interest in deciding the case on its merits. A stay of proceedings, which ends the prosecution, is an exceptional remedy available only in the clearest of cases.
Depending on the facts, a lawyer may seek exclusion of evidence, a different remedy under section 24(1), or, in rare cases, a stay.
The Charter rights discussed above also apply to young people, but the Youth Criminal Justice Act adds important protections, including special rules governing youth statements, access to counsel, and consultation with a parent or other qualifying adult.
For a parent-focused explanation of youth statements, release, diversion, sentencing, and youth records, see My Teen Was Charged With A Crime In Ontario: A Parent's Guide To The YCJA.
If you believe your Charter rights, or your teen's YCJA protections, were not respected during an arrest, our Criminal Law Services include reviewing the detention timeline, how the caution and counsel rights were implemented, and whether any search or statement was properly obtained.
Where a breach affected the evidence against you, we bring the appropriate Charter application. An early review of what actually happened, even after you've already spoken to police, can make a real difference to how the case unfolds.
Here are answers to some of the most common questions we hear about police stops and Charter rights.
Believing your Charter rights were not respected does not always mean the case is over, but it is worth having reviewed. If you have questions about how police handled your arrest, search, or questioning, our team can review what happened and explain the options available to you.
