Advance Medical Directives (Directives médicales anticipées), also known informally as a 'testament biologique' or living will in Quebec, are a formal legal document governed by the Loi concernant les soins de fin de vie (RLRQ c S-32.0001), articles 51 and following. This legislation, first adopted in 2014 and significantly amended in 2023 through Bill 38, established a comprehensive legal framework for end-of-life care decisions in Quebec, making the province a pioneer in codifying these rights in Canada.

The primary purpose of these directives is to allow any person of full age who is currently capable of expressing their wishes to formally document their medical decisions in advance, for a future time when incapacity prevents them from communicating. This proactive planning ensures that health care professionals have clear, legally binding guidance about the person's desires regarding specific treatments, life-prolonging measures, and end-of-life care options.

Under article 10 of the Code civil du Québec, every person has a fundamental right to personal integrity and inviolability, and no care may be given without that person's consent (art. 11 CCQ). Advance medical directives extend this right of self-determination into periods of incapacity. When a person becomes unable to consent to care, their directives replace their express consent, ensuring their autonomy is preserved even when they can no longer speak for themselves.

The scope of Quebec advance medical directives is broad and can encompass: (1) consent to or refusal of specific medical treatments and diagnostic procedures; (2) instructions regarding cardiopulmonary resuscitation (CPR) and Do Not Resuscitate (DNR) orders; (3) directives about artificial life support measures such as mechanical ventilation and artificial nutrition; (4) since the landmark 2023 amendments under Bill 38, an advance request for medical aid in dying (MAID / aide médicale à mourir) for persons whose natural death is reasonably foreseeable; (5) palliative care preferences including pain management strategies and preferred place of care; (6) religious, spiritual, and cultural preferences; and (7) organ and tissue donation wishes.

A critical feature of Quebec's advance directive system is the designation of a trusted person (personne de confiance) under article 53 of the Loi concernant les soins de fin de vie. Unlike a mandatary under a protection mandate, the trusted person does not make decisions but rather communicates the person's wishes to health care providers and ensures that the directives are respected. This distinction is important: the trusted person's role is informational and advocacy-based, not decisional.

The RAMQ maintains a provincial registry of advance medical directives, which health care professionals can consult through the Dossier santé Québec system. Under article 52 of the law, persons are encouraged to register their directives to ensure maximum accessibility. Registration does not replace physical copies but ensures the directives are available in any Quebec health care setting, even in emergencies.

All Quebec health care professionals are legally obligated to consult and respect these directives under the Loi concernant les soins de fin de vie. A professional who declines to follow directives for reasons of conscience must immediately notify the patient or representative and ensure continuity of care by referring to another provider.

Advance medical directives are relevant for any adult in Quebec who wishes to ensure their end-of-life health care wishes are respected, but they are especially critical in specific situations. They are essential planning tools for persons diagnosed with progressive or degenerative conditions such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, or ALS, who anticipate losing decision-making capacity over time. In these cases, the directives ensure that the person's wishes, recorded while they are fully capable, will guide care throughout the progression of the illness.

They are equally important for anyone planning surgery or hospitalization for a serious condition, as unexpected complications can rapidly render a person incapable of communicating. They are important for seniors approaching the later stages of life who wish to plan their end-of-life care thoughtfully, including whether they wish to remain at home, enter a palliative care residence, or receive care in a hospital. Persons with strong personal, religious, or ethical views about specific medical interventions — such as blood transfusions, mechanical ventilation, or resuscitation — benefit significantly from advance directives that clearly document these positions.

Since the 2023 amendments to the Loi concernant les soins de fin de vie, advance directives are also the mechanism through which persons who currently qualify for medical aid in dying (MAID) can make an advance request for MAID, to be carried out if they later lose the capacity to consent. This is particularly relevant for persons with early-stage Alzheimer's disease or other conditions that progressively affect cognitive capacity.

Advance medical directives should be reviewed and updated after any major health diagnosis, following significant changes in personal values or preferences, or when the persons designated as trusted person become unable to fulfill that role. They should ideally be prepared in consultation with one's physician, who can provide medical context for the choices being made.

A valid Quebec advance medical directive under the Loi concernant les soins de fin de vie must include specific elements to be legally effective. The declarant's complete identification is essential, including full legal name, date of birth, home address, and optionally the RAMQ health insurance number for registry purposes.

The designation of a trusted person (personne de confiance) under article 53 is a critical element. This person should be clearly identified by name, contact information, and relationship to the declarant, along with an explicit statement of their role as communicator of wishes rather than decision-maker.

The directive must clearly express the declarant's wishes regarding specific medical interventions: consent to or refusal of treatments (under arts. 10-11 CCQ on personal integrity), directives on CPR and life support, and since 2023, any advance request for MAID under arts. 29-29.1 of the Loi concernant les soins de fin de vie. If MAID is requested, the directive must specify the medical conditions under which the person wishes to receive it.

Palliative care preferences, including pain management wishes and preferred place of care, must be documented. Religious, spiritual, and cultural preferences that should guide care must be included. Organ and tissue donation wishes, expressed with as much specificity as needed, complete the substantive content.

Regarding form, article 51 of the Loi concernant les soins de fin de vie requires the directives to be signed in the presence of two qualifying witnesses. Each witness must attest that the declarant appeared to be of full age and capacity, and was acting freely and voluntarily. The witnesses must satisfy strict eligibility requirements: they cannot be beneficiaries under any will or life insurance of the declarant, cannot be the designated trusted person, and cannot be regular health care providers of the declarant. Both witnesses must sign immediately after the declarant.

While registration with the RAMQ registry is not mandatory, it is strongly recommended under article 52 to ensure the directives are accessible through the provincial health information system.
