Being held in a psychiatric facility is a serious restriction of liberty. You are entitled to know the legal authority being used, how long it lasts, and whether you can challenge it.
In Ontario, that authority is often described by reference to a form under the Mental Health Act. The number on the form is not merely administrative. It tells you whether you are being held for assessment, admitted as an involuntary patient, or kept in hospital under a renewal or continuation certificate. Other forms provide notice, trigger rights advice, or begin a review before the Consent and Capacity Board.
Detention does not automatically authorize treatment. The right to leave the hospital and the right to make treatment decisions are governed by different legal rules.
This guide explains the forms an adult patient is most likely to encounter in an Ontario psychiatric facility, the usual timeline, and the rights that arise along the way. It provides general legal information, not advice about a particular case.
The Timeline at a Glance
Stage | Main document | What it generally means | Maximum period |
Getting to hospital | Form 1, Form 2, or police apprehension | You may be taken to a psychiatric facility for examination or assessment | A Form 1 can be acted on for 7 days after it is signed; a Form 2 is also time-limited |
Psychiatric assessment | Form 1, with Form 42 notice | You may be detained for assessment | Up to 72 hours after admission under the application |
Initial involuntary admission | Form 3, with Form 30 notice | You may be detained as an involuntary patient | Up to 2 weeks |
First renewal | Form 4, with a new Form 30 | Continued involuntary detention | Up to 1 additional month |
Second renewal | Form 4, with a new Form 30 | Continued involuntary detention | Up to 2 additional months |
Third renewal | Form 4, with a new Form 30 | Continued involuntary detention | Up to 3 additional months |
Long-term continuation | Form 4A, with notice and mandatory review | Continued detention after the third renewal | Up to 3 months at a time |
Treatment incapacity | Form 33 | Notice that you were found incapable of consenting to a proposed treatment | The finding continues unless reversed, successfully challenged, or reassessed |
These periods are maximum durations, not minimums. A physician must change your status or discharge you when the legal requirements for detention are no longer met. The precise expiry date should appear on the relevant document.
Before the Form 1: How Can You Be Brought to Hospital?
Not everyone arrives at a psychiatric facility through the same route.
Form 1: Application by Physician for Psychiatric Assessment
A physician may complete a Form 1 after personally examining you and concluding that the statutory criteria are met. Depending on the circumstances, those criteria can involve risks of serious bodily harm, serious physical impairment, or substantial mental or physical deterioration, together with the other requirements in the Mental Health Act.
A Form 1 is not a final finding that you must remain in hospital. It authorizes you to be taken to a psychiatric facility and detained there for assessment.
The Form 1 must generally be acted on within seven days after the physician signs it. Once you are admitted under the Form 1, the assessment period can last no more than 72 hours.
During those 72 hours, the hospital must decide whether to:
release you;
ask whether you will remain as a voluntary patient; or
involuntarily admit you by completing a Form 3, if the statutory test is met.
Form 2: Order for Examination
A Form 2 is issued by a justice of the peace, usually after another person provides information under oath about why they believe an examination is necessary.
It authorizes police to apprehend you and take you to a physician for examination. It does not itself authorize a 72-hour psychiatric detention and does not guarantee that you will be admitted. After examining you, the physician decides whether the requirements for a Form 1 are met.
Brought in by Police: Police Apprehension Without a Form 1 or Form 2
In some circumstances, a police officer may apprehend a person without first obtaining a warrant or form and take them for examination. This authority comes from the Mental Health Act itself. The physician must then decide what, if any, further legal authority supports detention.
Form 42: the Notice that Explains a Form 1
If you are detained for assessment under a Form 1, you should receive a Form 42. The Form 42 is a notice to you. It is not the document that creates the detention.
It should tell you that an application for psychiatric assessment has been made, explain why you are being detained, and advise you of your right to retain and instruct a lawyer without delay.
There is no ordinary Consent and Capacity Board application to review a Form 1 because the assessment period is limited to 72 hours. That does not mean the hospital can ignore the legal requirements or hold you after the authority expires. Ask for copies of the Form 1 and Form 42 and confirm the date and time the 72-hour period began.
Form 3: Certificate of Involuntary Admission
A Form 3 changes your status from a person detained for assessment to an involuntary patient.
It may be completed only if a physician concludes that you meet one of the statutory tests for involuntary admission and that you are not suitable for admission as an informal or voluntary patient. Where you arrived under a Form 1, the physician who signs the Form 3 must be different from the physician who signed the Form 1.
A Form 3 lasts for no more than two weeks, calculated from the date it is signed.
Being on a Form 3 means the hospital may prevent you from leaving. It does not, by itself, establish that you are incapable of making treatment decisions and does not give the hospital a general power to medicate you without valid consent.
Form 30: Your Notice and the Gateway to Rights Advice
When a Form 3, Form 4, or Form 4A is completed, you must receive written notice of your involuntary status. For a Form 3 or Form 4, that notice is commonly called a Form 30.
The notice should identify the certificate, explain the basis for the physician’s decision, state when the certificate expires, and tell you that you may apply to the Consent and Capacity Board.
The physician must also promptly notify a Rights Adviser. A Rights Adviser is independent of your treatment team. They can explain the decision, your right to challenge it, your right to a lawyer, and how to start an application. Rights advice is not the same thing as legal representation or medical advice.
You have the right to retain and instruct a lawyer without delay. You can also ask the Rights Adviser for help applying for Legal Aid Ontario.
Form 4: Certificate of Renewal
If the attending physician believes you still meet the involuntary-admission test when the Form 3 is about to expire, the physician may complete a Form 4.
The permitted duration increases in stages:
the first Form 4 lasts up to one month;
the second Form 4 lasts up to two months; and
the third Form 4 lasts up to three months.
Each renewal is a new legal decision. The physician must reassess whether the statutory criteria continue to be met. The fact that an earlier form was valid does not automatically establish that the next one is valid.
You should receive fresh notice and rights advice each time your involuntary status is renewed. You may apply to the Board to challenge each new certificate even if you challenged an earlier one.
Form 4A: Certificate of Continuation
Older resources sometimes say that hospitals can keep issuing Form 4 renewals indefinitely. That is no longer the complete picture.
After the third Form 4, continued involuntary detention is documented through a Form 4A, called a Certificate of Continuation. Each Form 4A lasts for up to three months.
A Form 4A triggers a mandatory review of your involuntary status by the Consent and Capacity Board. The hospital gives the Board a Form 17 notifying it that the review must be scheduled. You do not have to file your own Form 16 to obtain this mandatory hearing.
Long-term patients on a Form 4A may also ask the Board to consider certain orders affecting the conditions of detention. Depending on the statutory requirements and the evidence, these can concern matters such as transfer, leave, security level, privileges, community access, and vocational, interpretation or rehabilitative services. A patient or someone acting on the patient’s behalf may use a Form 51 to request these orders.
Form 16: Challenging Involuntary Status
A Form 16 is the patient’s application asking the Consent and Capacity Board to review involuntary status.
You can ask your Rights Adviser or lawyer to help complete and send it. At the hearing, the physician bears the burden of proving that the legal requirements for involuntary detention are met.
The Board may confirm the certificate or rescind it. If the certificate is rescinded, the particular authority to detain you as an involuntary patient ends. That does not necessarily require the hospital to discharge you from all care: you may agree to remain voluntarily, and a later change in circumstances can lead to a new assessment under the legislation.
Board proceedings move quickly. A hearing is generally scheduled within seven days after the Board receives a completed application, subject to a permitted postponement or adjournment. Because the timeline is short, it is sensible to contact a lawyer as soon as you learn that a certificate has been signed.
Form 33: Notice to Patient of Finding of Incapacity
Detention and treatment capacity are separate.
A person can be an involuntary patient and still be capable of making a treatment decision. A voluntary patient can also be found incapable of making a particular treatment decision.
Under the Health Care Consent Act, a person is capable with respect to a treatment if they can understand the information relevant to the decision and appreciate the reasonably foreseeable consequences of giving or refusing consent. Capacity is decision-specific and can change over time.
If a physician finds that you are incapable of consenting to treatment of a mental disorder in a psychiatric facility, you should receive a Form 33. It tells you about the finding, your right to meet with a Rights Adviser, and your right to apply to the Consent and Capacity Board for a review.
The application to challenge treatment incapacity is made using the Board’s Form A. The Board decides whether the legal test for capacity was met. It does not decide whether the proposed treatment is a good idea.
Unless a statutory exception applies, treatment generally cannot begin while the incapacity review and any appeal are still open or pending. Urgent treatment rules are more limited and fact-specific.
If the incapacity finding remains in place, consent must generally come from the highest-ranking available substitute decision-maker authorized by the Health Care Consent Act. That person must follow any applicable prior capable wish. If there is no applicable wish, the substitute decision-maker must apply the statutory best-interests factors.
What About Property and Financial Decisions?
While you are an inpatient, a physician may also assess whether you are capable of managing property.
A Form 21 is a certificate of incapacity to manage property.
A Form 24 gives notice that the physician has found you capable of managing property after an earlier finding of incapacity.
A Form 21 can result in the Public Guardian and Trustee becoming statutory guardian of property, subject to the legislation and any existing authority. You are entitled to notice, rights advice, and an opportunity to ask the Consent and Capacity Board to review the finding. Property incapacity is distinct from treatment incapacity and involuntary status.
Other Forms Directly Related to Involuntary Status
Form 5: Change to Informal or Voluntary Status
A Form 5 records a change from involuntary to voluntary status. If you become a voluntary patient, you may generally leave, although the hospital may wish to reassess you if new facts raise concerns under the Mental Health Act.
A Form 5 is completed when the attending physician determines that you no longer meet the legal requirements for involuntary admission. It terminates your involuntary status under the existing Certificate of Involuntary Admission, Certificate of Renewal, or Certificate of Continuation. You must then be continued as an informal or voluntary patient.
A Form 5 changes your legal status but does not necessarily discharge you from hospital. A voluntary patient is choosing to remain and may generally decide to leave; different rules may apply to an informal patient. Form 5 also does not determine treatment capacity, and it does not prevent a later assessment or detention if circumstances change and the legal requirements are met again.
Form 9: Return of an Involuntary Patient
If an involuntary patient leaves a psychiatric facility without authorization, the officer in charge may issue a Form 9 directing police to return the patient. The authority is time-limited and depends on the patient’s underlying involuntary status.
Your Practical Rights on the Psychiatric Unit
If you do not understand why you are being held, ask the hospital to tell you:
What is my current legal status?
Are you voluntary, informal, detained for assessment, or involuntary?
Which form is currently in effect?
Ask for the number and a copy.
When was it signed, and exactly when does it expire?
Write down the date and time.
Have I been given every required notice?
The document creating the authority and the notice explaining it may be different forms.
Has a Rights Adviser been contacted?
Ask to speak privately with the Rights Adviser. You can also reach out to the Psychiatric Patient Advocate Office (PPAO) directly by phone or email.
Can I contact a lawyer now?
You have the right to retain and instruct counsel without delay.
Have I been found incapable of any decision?
Ask whether the decision concerns treatment, property, personal health information, or something else. Each has a different legal test and review route.
Is any Board hearing already scheduled?
A hearing may result from your application or may be mandatory.
Also keep copies of your forms, notices, rights-advice documents, and any application sent to the Board. If you cannot safely keep paper copies, ask your lawyer or a trusted person to retain them.
What Happens at a Consent and Capacity Board hearing?
The Consent and Capacity Board is an independent adjudicative tribunal. It is not part of your treatment team.
Hearings are usually held quickly, often by videoconference or at the hospital. You may have a lawyer, present evidence, call and question witnesses, challenge the other side’s evidence, and make legal submissions. The precise issue depends on the application. For example, the Board may be deciding whether you meet the test for involuntary detention or whether you are capable of making a particular treatment decision.
The Board usually gives its decision shortly after the hearing. A party can request written reasons. Appeal rights and deadlines are strict, so obtain legal advice promptly if you are considering an appeal.
The Most Important Things to Remember
“Being on a form” is not a complete explanation. You are allowed to ask which form, when it began, and when it expires.
A Form 1 only permits assessment for up to 72 hours. It is not an involuntary-admission certificate.
A Form 3 begins involuntary admission and lasts up to two weeks.
Forms 4 renew involuntary status for one month, then two months, then three months.
A Form 4A follows the third Form 4, lasts up to three months, and triggers mandatory Board review.
A Form 30 gives notice of involuntary status and review rights.
A Form 33 concerns treatment incapacity. It is separate from detention.
Detention does not automatically authorize treatment.
You may speak with a Rights Adviser and retain and instruct a lawyer.
You can ask the Consent and Capacity Board to review many of these decisions, and the process moves quickly.
Stages of Involuntary Psychiatric Hospitalization in Ontario
Getting Legal Help
Mental health forms can affect liberty, bodily autonomy, finances, and access to the community. Small details can matter, including who signed a form, what information was available, whether the statutory criteria were addressed, whether notice and rights advice were provided, and whether the document was completed before the previous authority expired.
