Advance Care Directive (Canada)

An Advance Care Directive in Canada records a person’s wishes about future medical treatment to guide care if they lose capacity to decide, governed primarily by provincial health-care consent and substitute-decision legislation.

Canada's advance care directive framework is governed by provincial and territorial legislation, as healthcare is a matter of provincial jurisdiction under sections 92(7) and 92(16) of the Constitution Act, 1867. Each province uses different terminology and has distinct formal requirements. In Alberta, the governing legislation is the Personal Directives Act (R.S.A. 2000, c. P-6), and the document is called a Personal Directive. In British Columbia, the Representation Agreement Act (R.S.B.C. 1996, c. 405) governs, and the document is a Representation Agreement (Section 7 for routine healthcare decisions; Section 9 for major health decisions and personal care). In Ontario, the Health Care Consent Act, 1996 (S.O. 1996, c. 2, Sched. A) and the Substitute Decisions Act, 1992 (S.O. 1992, c. 30) provide the framework — Ontarians express healthcare wishes in a Power of Attorney for Personal Care under the Substitute Decisions Act. In Manitoba, the Health Care Directives Act (C.C.S.M. c. H27) applies; in Saskatchewan, The Health Care Directives and Substitute Health Care Decision Makers Act (S.S. 1997, c. H-0.001.1); and in Nova Scotia, the Medical Consent Act (R.S.N.S. 1989, c. 279) and the Personal Directives Act (S.N.S. 2008, c. 8).

The common law doctrine of informed consent — recognized by the Supreme Court of Canada in Malette v. Shulman (1990) ONCA and reaffirmed in Starson v. Swayze [2003] 1 SCR 722 — establishes that a capable adult has the right to refuse any medical treatment, and that a valid advance directive expressing refusal of treatment is binding on healthcare providers even when the patient is incapable. The Supreme Court's decision in Carter v. Canada (Attorney General) [2015] 1 SCR 331 confirmed Canadians' constitutional right under the Canadian Charter of Rights and Freedoms, section 7, to make end-of-life decisions — a right that advance care directives are designed to exercise.

The consent hierarchy for incapable patients, codified in Ontario's Health Care Consent Act, 1996, s. 20, establishes the order in which SDMs are recognized when no proxy has been formally appointed: spouse or partner; adult children; parents; siblings; other relatives; and the Public Guardian and Trustee as a last resort. An advance care directive that appoints a specific SDM overrides this default hierarchy, allowing the maker to choose a trusted friend, domestic partner, or other person not on the default list.

Medical assistance in dying (MAID), now regulated under the Criminal Code (R.S.C., 1985, c. C-46) as amended by Bill C-7 (S.C. 2021, c. 2), permits eligible Canadians with grievous and irremediable medical conditions to request MAID. The advance care directive can document a person's values about end-of-life care and may inform discussions about MAID, but as of 2026, advance requests for MAID (by persons who are currently capable but anticipate future incapacity) are the subject of ongoing regulatory and legislative consideration under Bill C-62.

A Canadian Advance Care Directive is needed whenever an adult wishes to express their healthcare preferences in advance, to confirm those preferences are respected if they later become mentally incapable of communicating them — a situation that can arise suddenly through accident, stroke, or medical crisis, or gradually through cognitive decline.

Sudden incapacity following an accident or acute medical emergency is the scenario most people imagine when considering an advance care directive. Accidents, cardiac events, and strokes can render a previously healthy adult incapable of communicating almost instantaneously. Without a directive or appointed SDM, family members may disagree about the appropriate course of treatment, and healthcare providers must rely on the default SDM hierarchy under provincial legislation — which may not reflect the patient's actual preferences.

Diagnosis of a progressive or terminal illness — including dementia, ALS, Parkinson's disease, cancer, or heart failure — is a common trigger for preparing an advance care directive. Receiving a serious diagnosis while still mentally capable is the ideal time to document treatment preferences, values about quality of life, and instructions about palliative or hospice care, allowing the person to participate actively in advance care planning discussions with physicians, family, and their appointed SDM.

Elective surgery or medical procedures that carry a risk of incapacity — major cardiac surgery, neurosurgery, or any procedure requiring general anesthesia — prompt healthcare providers at hospitals including Toronto General Hospital, Vancouver General Hospital, and Calgary Foothills Medical Centre to ask patients whether they have an advance care directive on file. Having a directive prepared before surgery confirms that the patient's wishes are known and documented.

Admission to a long-term care facility or nursing home triggers mandatory advance care planning discussions under provincial long-term care regulations. Ontario's Fixing Long-Term Care Act, 2021 (S.O. 2021, c. 39, Sched. 1) requires long-term care homes to confirm that residents and their SDMs are engaged in advance care planning and that documented wishes are incorporated into the resident's plan of care.

Estate planning is an appropriate time to prepare all personal planning documents together — a Last Will and Testament, Power of Attorney for Property, Power of Attorney for Personal Care (or provincial equivalent), and an Advance Care Directive. A thorough estate plan prepared with a lawyer at firms such as McCarthy Tétrault, Fasken, or Torys reflects the full spectrum of an adult's legal and personal wishes.

A complete Canadian Advance Care Directive must contain specific elements that vary by province but share a common core, addressing the maker's identity, capacity, healthcare wishes, substitute decision-maker appointment, and formal execution requirements.

Maker identification requires the full legal name, date of birth, and residential address of the person making the directive. The document should confirm that the maker is a mentally capable adult at the time of signing — mental capacity means the ability to understand the information relevant to making a healthcare decision and to appreciate the reasonably foreseeable consequences of a decision or lack of decision, as defined in Ontario's Health Care Consent Act, 1996, s. 4.

Values and beliefs statement, while not legally required, is among the most meaningful parts of the directive. This section expresses the maker's values about quality of life versus length of life, views on aggressive medical intervention versus comfort-focused care, spiritual or religious beliefs that should guide healthcare decisions, and any particular circumstances in which the maker would consider life not worth prolonging. Courts and healthcare providers give significant weight to a values statement when interpreting ambiguous instructions.

Healthcare instructions address specific medical scenarios and treatments. The directive should express the maker's wishes — accept, refuse, or leave to the discretion of the SDM — regarding: cardiopulmonary resuscitation (CPR); mechanical ventilation and artificial respiratory support; tube feeding and parenteral nutrition; dialysis; blood transfusions; antibiotic treatment for infections; surgery in an end-stage illness; palliative sedation; and hospice or palliative care. Instructions should be expressed in plain language and should cover both sudden incapacity and progressive decline scenarios.

Substitute decision-maker appointment names the person or persons the maker trusts to make healthcare decisions on their behalf. The appointed SDM should be named with full legal name and contact information, along with one or more alternate SDMs in case the primary SDM is unavailable or unwilling to act. The directive should specify whether the SDM has discretion to make decisions not addressed in the directive, or whether the SDM is strictly bound by the written instructions.

Organ and tissue donation wishes express whether the maker consents to donation of organs and tissues for transplantation and any limitations on which organs or tissues may be donated. In Canada, organ donation registration is managed provincially — in Ontario through ServiceOntario, in BC through BC Transplant, and in Alberta through the Alberta Organ and Tissue Donation Registry — but the advance care directive provides supplementary documentation of the maker's wishes.

Formal execution requirements must meet the provincial standard for the directive to be valid. In Alberta (Personal Directives Act, s. 7), the directive must be signed by the maker and witnessed by one qualified adult witness who is not the agent. In BC (Representation Agreement Act, s. 13), a Section 9 agreement requires two witnesses, or one notary or lawyer, who are not the representative, the representative's spouse, or certain other disqualified persons. In Ontario (Substitute Decisions Act, 1992, s. 10), a power of attorney for personal care requires two witnesses, neither of whom is the grantor's spouse, partner, child, the person's attorney for property, or their SDM. The document should be dated, and the maker and witnesses should sign in each other's presence.

Storage and distribution instructions should direct that the directive be filed with the maker's family physician (in Ontario, with the Health Care Connect registration), shared with the appointed SDM, and kept in an accessible location at the maker's residence. Provincial advance care directive registries (such as BC's Health Care Directive Registry) allow the directive to be accessed by healthcare providers across the province.

Under Canadian law, PIPEDA and provincial privacy legislation govern personal data processed under this agreement. The Competition Act (R.S.C. 1985, c. C-34), enforced by the Competition Bureau, protects consumer rights. Section 15 of the Canada Business Corporations Act governs corporate obligations. Provincial superior courts and the Federal Court of Canada have jurisdiction for civil matters. The Canada Revenue Agency (CRA) administers tax compliance obligations.
