Mental Health Rights in Ontario

What is this right?
All 13 provinces and territories have their own mental health legislation. Involuntary commitment (also called certification) requires that:
- A mental disorder is present
- There is a risk of serious harm to the person or others
- The person cannot be assessed or treated voluntarily
Hold durations vary by province. In Ontario, an initial 72-hour assessment can lead to formal certification. In BC, the initial hold is 48 hours.
There is a critical difference between provinces on treatment consent: in Ontario, a capable patient can refuse treatment even while involuntarily detained. In BC, the facility director can override a patient's refusal.
Patients who are involuntarily committed have the right to a lawyer, a review board hearing, and periodic reviews of their status. Some provinces also allow Community Treatment Orders for supervised treatment outside the hospital.
When does it apply?
- Anyone subject to involuntary psychiatric assessment or admission in Canada.
- Anyone receiving mental health treatment, whether voluntary or involuntary.
What to Do If You Are Involuntarily Committed to a Psychiatric Facility in Canada
- Know your rights — you must be informed of them upon involuntary admission.
- Contact a lawyer or legal aid immediately if you are involuntarily committed.
- Apply for a review board hearing — in Ontario, the Consent and Capacity Board must hear your case within 7 days.
- Designate a power of attorney for personal care in advance so your treatment wishes are respected if you become incapable.
- Family members can request a physician assessment if someone they care about is at risk of harming themselves or others.
What should you NOT do?
- Don't assume you lose all your rights when involuntarily committed — you retain your civil rights, the right to vote, and the right to a lawyer.
- Don't miss the review board deadline — filing quickly is important to challenge your detention.
- Don't assume all provinces handle consent the same way — the rules on refusing treatment vary significantly between provinces.
- Don't confuse police apprehension with a criminal charge — being brought to hospital by police for a mental health assessment is a health matter, not a criminal one.
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.
