Mental Health Rights — Ontario
Sourced from Canadian federal statutes and official sources. Provincial information reflects each province's own legislation and court rulings. Written in plain language for general understanding — this is educational content, not legal advice. Our editorial standards
What is this right?
All 13 provinces and territories have their own mental health legislation. Involuntary commitment (or certification) typically requires three elements:
- A mental disorder is present
- There's a risk of serious harm to the person or others
- The person cannot be assessed or treated voluntarily
Initial holds vary. Ontario typically allows a 72-hour assessment before formal certification. BC's first hold is 48 hours. Lengths and renewal rules continue to differ from there.
The most important provincial divergence is on treatment consent. In Ontario, a capable patient can refuse treatment even while involuntarily detained — that line was confirmed by the Supreme Court in Starson v. Swayze (2003). In BC, the facility director can override the refusal. Same Charter, different provincial frameworks, very different lived experiences.
Anyone involuntarily committed has the right to a lawyer, a review board hearing, and periodic reviews. Some provinces also use Community Treatment Orders for supervised treatment outside hospital.
When does it apply?
- Anyone subject to involuntary psychiatric assessment or admission in Canada.
- Anyone receiving mental health treatment, voluntary or otherwise.
What to Do If You Are Involuntarily Committed to a Psychiatric Facility in Canada
The first hours of any involuntary admission shape what happens next. Know the rights and use them.
- Insist on being told your rights. They have to be explained on admission.
- Get a lawyer or legal aid immediately. Do not wait.
- Apply for a review board hearing. In Ontario, the Consent and Capacity Board must hear it within 7 days.
- Designate a power of attorney for personal care in advance so your treatment wishes are honoured if capacity fails.
- Family members can request a physician assessment if someone they care about is at risk.
What should you NOT do?
- Don't assume civil rights vanish on admission. They don't — the right to vote, the right to counsel, and the rest survive.
- Don't miss the review-board window. Filing quickly is what challenges the detention.
- Don't assume the consent rules in your province match somewhere else. They diverge sharply.
- Don't confuse police apprehension under mental-health law with a criminal arrest. Being brought to hospital is a health matter, not a charge.
How Ontario differs from federal law
Ontario's Mental Health Act, R.S.O. 1990, c. M.7 sets out the rules for psychiatric assessment, admission, and the rights of people in psychiatric facilities. It provides important protections against involuntary detention.
- A person can only be held involuntarily in a psychiatric facility under a Form 1 (Application by Physician for Psychiatric Assessment) if a physician has personally examined them within the previous 7 days and believes they meet the criteria: the person has a mental disorder, is likely to cause serious bodily harm to themselves or others, or is likely to suffer substantial mental or physical deterioration without hospitalization.
- A Form 1 allows a maximum 72-hour hold for assessment. If the hospital wants to keep you longer, a psychiatrist must complete a Certificate of Involuntary Admission (Form 3). A second certificate extends the hold to 2 weeks, then 1 month, then 2 months, then 3 months at a time.
- Involuntary patients have the right to a hearing before the Consent and Capacity Board (CCB) to challenge their detention. The hospital must tell you about this right and provide a Rights Adviser who explains your rights and helps you apply for a hearing.
- You have the right to retain and instruct a lawyer. Legal Aid Ontario provides duty counsel at CCB hearings.
- Community Treatment Orders (CTOs) can require a person to follow a treatment plan in the community as an alternative to hospitalization. CTOs have strict criteria and can also be challenged at the CCB.
- Voluntary patients can leave at any time — a hospital cannot convert you from voluntary to involuntary status unless you meet the criteria for involuntary admission.
Additional Steps in Ontario
If you or a loved one is involuntarily detained, ask to speak to the Rights Adviser — every psychiatric facility must have one. You can request a CCB hearing to challenge the detention, and the hearing must be held within 7 days. Legal Aid Ontario provides free legal representation at CCB hearings.
