Refusing Psychiatric Treatment in Ontario: Your Rights, CCB Hearings & Legal Process Explained

Geenishka Khanna

Refusing medical treatment — especially psychiatric care — can be one of the most difficult and emotional decisions a person makes. In Ontario, the Consent & Capacity Board (CCB) exists to protect both patient rights and public safety when there’s a disagreement about whether someone is capable of making that choice.

If you’ve ever wondered “Can I legally refuse psychiatric treatment in Ontario?” or “What happens if my doctor says I’m incapable of making my own decisions?” — this guide breaks it all down.

We’ll cover:

  • What the Ontario CCB is and why it exists

  • How “capacity” is defined under Ontario law

  • What happens when someone refuses psychiatric treatment

  • How the CCB hearing process works

  • The landmark Starson v. Swayze case

  • Your legal rights before, during, and after a hearing

  • How appeals work if you disagree with a decision

    What is the Ontario Consent & Capacity Board (CCB)?

    The Consent & Capacity Board is an independent legal tribunal under Ontario’s Health Care Consent Act and related laws.

    Its main job? To resolve disputes between patients and healthcare providers about:

    • A person’s capacity to consent to or refuse treatment

    • Decisions about admission to psychiatric facilities

    • Whether a substitute decision-maker (SDM) is needed

    • Reviews of involuntary admission under the Mental Health Act

    The CCB sits at the intersection of mental health law, patient rights, and medical ethics, ensuring decisions are fair, transparent, and legally sound.

Consent & Capacity Board: Refusing Treatment Explained

Capacity vs. Incapacity: How the Law Decides

In Ontario, capacity isn’t about whether your decision is “good” — it’s about whether you meet two legal criteria:

  1. Understanding – You must understand the relevant information about the treatment, including what it is, its benefits, risks, and alternatives.

  2. Appreciation – You must be able to appreciate the reasonably foreseeable consequences of accepting or refusing treatment.

Key point: Having a mental illness does not automatically mean you’re incapable. A person with a psychiatric diagnosis can still be capable under the law.

If a doctor decides you’re incapable, they must:

  • Explain why

  • Inform you of your right to challenge the decision before the CCB

    When Patients Refuse Psychiatric Treatment

    Refusal of psychiatric treatment is one of the most common reasons for a CCB hearing. It can happen when:

    • A patient disagrees with their psychiatrist’s diagnosis

    • They believe medication will cause harm or severe side effects

    • They prefer alternative or holistic treatments

    • They’ve had negative past experiences with psychiatric care

    If a healthcare provider finds you incapable, they may turn to a substitute decision-maker (often a family member) — unless you appeal to the CCB.

    How the CCB Hearing Process Works

    If you challenge a finding of incapacity, the process moves quickly:

    1. Application Filed – You (or your lawyer) submit your application within the set time limit.

    2. Hearing Scheduled – Usually within 7 days to protect your rights.

    3. Evidence Presented –

      • Doctors explain why they believe you’re incapable

      • You can testify, bring witnesses, or submit expert reports

    4. Legal Representation – You can have a lawyer, and legal aid may be available.

    5. Decision – The CCB issues a written decision, often within 1 day.

    The Board does not decide whether refusing treatment is wise — only whether you meet the legal test for capacity.

    Landmark Case: Starson v. Swayze

    The 2003 Supreme Court of Canada case Starson v. Swayze remains one of the most important rulings on psychiatric treatment refusal.

    • Background: Professor Starson, a physicist with bipolar disorder, refused psychiatric medication while involuntarily detained.

    • CCB Decision: They found him incapable.

    • Appeal: The Supreme Court ruled he was capable — because he understood and appreciated the consequences of his choice, even if the decision carried risks.

    Impact: This case confirmed that the right to refuse treatment stands if you meet the legal criteria for capacity — even if your decision goes against medical advice.

    Your Legal Rights in a CCB Dispute

    You have the right to:

    • Be informed of a finding of incapacity and your right to a hearing

    • Have a lawyer (legal aid may be available)

    • A timely hearing (within days)

    • Participate fully in presenting evidence and questioning witnesses

    • Appeal the decision to the Ontario Superior Court of Justice

Appealing a CCB Decision

If you disagree with the CCB’s ruling, you can appeal to the Ontario Superior Court of Justice.

  • This is not a full re-hearing — the court reviews whether the CCB applied the law correctly.
  • If successful, the court can overturn the finding and restore your right to make your own decisions.

    Why This Matters

    Understanding the CCB process is essential for protecting your autonomy and ensuring your voice is heard in mental health decisions.
    By knowing your rights, you can:

    • Communicate better with healthcare providers

    • Challenge capacity findings effectively

    • Avoid losing legal control over your treatment choices

    The Ontario Consent & Capacity Board plays a critical role in balancing patient rights and medical care. Refusing psychiatric treatment is a deeply personal decision — and the law focuses on your ability to understand and appreciate the consequences, not on whether others agree with your choice.

    Cases like Starson v. Swayze are a reminder that in Ontario, capacity means control over your own treatment decisions — even in the face of disagreement with your doctor.
