Being arrested or detained by the police is unsettling, but knowing your rights can help you prevent errors that harm your defence in the long run. It can help prevent self-incrimination, ensure access to legal counsel, and protect you from unlawful treatment during the legal process.
In Ontario, you are protected by specific legal rights designed to ensure fair treatment and to safeguard your ability to build a proper legal defence. A clear understanding of these protections can make a significant difference when navigating the criminal justice system.
Section 10 of the Canadian Charter lists three core guarantees that are triggered the moment you are detained or arrested: to be told why you are being held, to speak with counsel without delay, and to challenge the legality of the detention.
Other Charter sections (7, 8, 9, 12) and Ontario provincial regulations build on those guarantees. These rights are in place to ensure that you are treated fairly, that the legal process is conducted properly, and that you can protect yourself and exercise your legal options effectively.
In summary, upon arrest or detention, you have the:
Police must tell you—promptly and in plain language—why you are being arrested or detained. They cannot rely on vague phrases such as “outstanding matters.” The disclosure must be enough for you to decide whether to cooperate and to instruct counsel. Failing to provide a clear reason can make the detention arbitrary and lead to the exclusion of evidence.
Nothing in Canadian law forces you to answer investigative questions. You must give your name, date of birth, and address only if:
Outside those narrow settings, you may politely decline to answer. Remaining silent helps protect against self-incrimination and ensures that your statements are not used against you in court. Courts have repeatedly confirmed that silence cannot be used as evidence of guilt.
It is recommended that you clearly state your intention to exercise this right and refrain from answering any questions until you have consulted with a lawyer.
You have the immediate right to speak to a lawyer of your choice in private. Police must:
Section 8 of the Charter protects your reasonable expectation of privacy. Police generally need a warrant to search your home, digital devices, or person unless an established warrantless-search power applies (e.g., a pat-down for officer safety during arrest). Evidence gathered through an unlawful search can be excluded under section 24(2).
That said, you can refuse consent to any search not legally justified by a warrant or lawful authority. If you voluntarily consent to a search, it may limit your ability to challenge the search later in court. Remember to always respectfully ask if you are legally required to comply before agreeing to a search.
Section 12 bars cruel or degrading treatment. While in custody, you have the right to humane treatment, which includes protection of your dignity and access to basic needs. These rights include:
Young persons under the age of 18 are entitled to special legal protections and rehabilitation under the Youth Criminal Justice Act (YCJA). These protections recognise that youth may not fully understand the legal process and aim to ensure they are treated fairly and appropriately.
When a youth is arrested or detained, they are entitled to additional rights beyond those provided to adults. These enhanced protections include:
These safeguards are designed to ensure that youth are fully informed of their rights and able to participate in the legal process with appropriate support. In addition, officers must consider warnings, cautions, or diversion programs before laying a charge.
Vulnerable individuals, including those with mental health conditions, language barriers, or disabilities, are entitled to specific protections during arrest or detention in Ontario. These safeguards help ensure that every individual fully understands their rights and receives fair treatment under the law.
Key protections for vulnerable individuals include:
These measures help protect vulnerable individuals from misunderstandings and ensure that their legal rights are fully respected.

Understanding your rights during an arrest can be challenging, especially under stressful circumstances. Below are clear answers to some of the most common questions when dealing with police in Ontario.
Usually, yes. Once you have had a reasonable chance to get legal advice, officers may resume the interview. They need not re-advise you of your rights unless the situation changes significantly, such as new, more serious charges. The Supreme Court confirmed this in R v Sinclair, where the Court held that the right to counsel does not guarantee a lawyer’s presence during questioning. Nevertheless, you maintain your right to silence at all times and are not obligated to answer any further questions. Exercising your right to remain silent can help protect your legal interests.
If you clearly request to speak to a lawyer after being detained or arrested, police must stop questioning you until you have had a reasonable opportunity to contact and consult with one. It is important to state this request clearly and assertively to ensure that your right to counsel is respected. Police have to give you a second consultation only if there is a material change in circumstances: for example, they introduce new evidence, propose a polygraph, or you clearly do not understand your initial advice. Simply repeating “I want my lawyer” will not oblige officers to halt the interview once the first consultation has occurred.
It depends on the context. You must produce your driver’s licence, ownership, and insurance when lawfully stopped while driving. You may refuse during a casual encounter or street check; the 2017 Ontario regulation on carding explicitly says you may decline to identify yourself without penalty. During investigative detention or arrest, giving your real name and date of birth avoids an “obstruct police” charge. Outside those situations, you are free to remain silent.
