Manitoba Informed Consent Laws (2026)

What is this right?
Before any treatment, the law requires the doctor to give you enough information to make a real decision. The Supreme Court's Reibl v. Hughes (1980) and Hopp v. Lepp (1980) anchor this duty in Canadian law. The information has to cover:
- The nature of the treatment
- Expected benefits
- Material risks and side effects
- Alternatives, including doing nothing
- The consequences of refusing
Consent must be voluntary. Pressure invalidates it. And capacity is judged per decision — you can be capable of consenting to one treatment and not another, on the same day.
If you're found incapable, a substitute decision-maker (SDM) steps in. The hierarchy runs: guardian, power of attorney for personal care, spouse, adult child. The SDM's job isn't to do what they'd want — it's to do what you would have wanted.
In a genuine emergency, a doctor can treat without consent if you are incapable and no SDM is available. That carve-out is narrow.
When does it apply?
- Every patient in Canada, regardless of age or status.
- Applies to any proposed treatment, procedure, diagnostic test, hospital admission, or research study.
What to Do If a Canadian Doctor Treated You Without Your Informed Consent
- Ask questions. Persistently. You have the right to understand the treatment before agreeing.
- Request written information on your diagnosis, options, and risks.
- Designate a power of attorney for personal care while you're still capable. Future-you will thank present-you.
- Create an advance directive for the treatments you do or don't want.
- If you believe your consent rights were violated, contact a patient ombudsman for the province.
What should you NOT do?
- Don't sign consent forms without reading them. Take the time. The form is the record.
- Don't assume silence is consent. The doctor needs a clear yes.
- Don't let yourself be rushed outside genuine emergencies where delay would be life-threatening.
- Don't forget you can withdraw consent at any time — even after you've signed, even mid-procedure where it's safe to stop.
How Manitoba differs from federal law
Informed consent is a legal and ethical requirement for all medical treatment in Manitoba, rooted in common law and reinforced by professional standards.
- Before any medical treatment or procedure, your healthcare provider must explain: the nature of the treatment, the expected benefits, the material risks and side effects, alternative treatments (including no treatment), and the consequences of refusing.
- You have the right to ask questions and receive answers in language you can understand before making a decision.
- Consent must be voluntary — no one can force you to accept treatment (except in specific situations under mental health legislation).
- Under Manitoba's Health Care Directives Act, CCSM c. H27, you can create an advance directive (living will) that states your wishes about future medical treatment if you become unable to make decisions.
- If you are unable to consent (unconscious, incapacitated), a substitute decision-maker can consent on your behalf — typically a family member or a person designated under your health care directive or power of attorney.
Additional Steps in Manitoba
If you feel a medical procedure was performed without your informed consent, you can: file a complaint with the College of Physicians and Surgeons of Manitoba at 204-774-4344, contact the Manitoba Patient Advocate, or consult a lawyer about a potential civil claim for battery or negligence. To create an advance directive, use the forms available from Manitoba Health or consult a lawyer.
