Do Not Resuscitate (DNR) Orders in Canada — How They Actually Work

An 84-year-old in Mississauga had spent two years carefully writing a personal-care plan with her family. She had a Continuing Power of Attorney for Personal Care naming her daughter. She had written a clear advance directive saying she did not want to be resuscitated if her heart stopped. One morning she collapsed at home. The paramedics arrived, found no DNR form on the fridge or in her medical kit, and followed protocol — full CPR, broken rib, intubation, four days in the ICU before the family was able to redirect care.

The mistake was not a failure of the family or the paramedics. It was a misunderstanding of what counts as a DNR in Canada. The advance directive in the drawer was a personal statement of wishes. The legal weight she needed at the scene of an emergency was a physician-signed paramedic-facing DNR form. The two documents do different jobs and are not interchangeable.

This guide walks the distinction, the provincial forms, and what families generally need to do to make a do-not-resuscitate wish actually take effect at the moment it matters.

For the upstream documents — the personal-care POA, the advance directive, the living will — see our pillar on estate planning in Canada and the companion piece on advance care directives in Canada.

What a DNR actually is #

A do-not-resuscitate order — sometimes called an Allow Natural Death (AND) order, particularly in palliative-care settings — is a clinical instruction. It is signed by a physician or, in some provinces, a nurse practitioner. It lives in the patient's medical chart. Its function is to direct the healthcare team to withhold cardiopulmonary resuscitation (CPR) if the patient stops breathing or their heart stops beating.^[4]

What a DNR is not is a personal-care plan, a values statement, a living will, or an advance directive. Those documents are upstream of the clinical order. They guide the substitute decision-maker and the treating team. They do not, by themselves, prevent the act of resuscitation.

The structural difference matters because the moment of cardiac arrest does not allow time for the substitute decision-maker to be reached, for documents to be retrieved from a safety deposit box, or for a chart review. Paramedics work in seconds. They look for a specific province-appropriate form, physically present, signed by a physician, that authorises them to withhold CPR. If they cannot see that form, they perform CPR — that is the default in every Canadian province.

The provincial-form picture #

Each province has its own form or family of forms. The picture as of 2026 looks roughly like this.

Ontario. The Ministry of Health Do Not Resuscitate Confirmation Form is the paramedic-facing instrument.^[5] It is generally signed by a physician, registered nurse, or registered practical nurse. The patient or substitute decision-maker also signs to confirm consent. Once signed, paramedics will honour the form if it is physically present at the scene.

British Columbia. BC uses the No CPR form (sometimes called the MOST — Medical Orders for Scope of Treatment) for inpatient settings, and a separate community-facing No CPR form for out-of-hospital. A physician signs. The patient or representative consents.

Alberta. Alberta's Goals of Care Designation framework includes specific designations (C1, C2, M1, M2, etc.) that capture the patient's resuscitation preferences. The designation is signed by a physician and recorded on a Personal Directive or Goals of Care form. The Personal Directive itself is the upstream document under the Personal Directives Act, RSA 2000, c P-6.^[2]

Saskatchewan, Manitoba, Nova Scotia, New Brunswick, PEI, Newfoundland and Labrador. Each province has its own paramedic-facing DNR form, generally signed by a physician and the patient or substitute decision-maker. The mechanics are broadly similar but the specific form is different.

Yukon, Northwest Territories, Nunavut. Each territory has its own form. The remoteness of many communities makes the paper-trail discipline especially important — paramedics or community health workers will not be able to retrieve clinical records on short notice.

The forms are generally not interchangeable across provinces. A Manitoba form may not be recognised by Ontario paramedics responding outside Toronto. If a patient with a DNR is travelling or splits time between provinces, a province-specific form should ideally be in place at each location.

The legal architecture underneath #

The clinical DNR order sits within a broader provincial framework of substitute decision-making. Ontario's Health Care Consent Act, 1996 is the governing statute for consent to and refusal of treatment.^[1] BC's Health Care (Consent) and Care Facility (Admission) Act serves the same role.^[3] Alberta uses the Personal Directives Act for advance directives and the Adult Guardianship and Trusteeship Act for guardianship.^[2]

The framework recognises three levels of input into the DNR question.

The first is the patient's own, current capable consent. If you are capable and you tell your physician you do not want CPR, the physician can issue a DNR order in your chart.

The second is the patient's advance directive or personal directive, executed while capable, that speaks to the situation. This guides the substitute decision-maker when you are no longer capable. It is not a medical order on its own.

The third is the substitute decision-maker — typically your attorney for personal care, your representative under a BC representation agreement, your agent under an Alberta personal directive, or a statutorily designated family member if no document is in place. The substitute decision-maker can consent to or request a DNR on your behalf when you are incapable, generally guided by your prior expressed wishes or your best interests.

A physician's role is to weigh clinical appropriateness alongside patient autonomy. In settings where CPR is medically futile — typically advanced terminal illness — a DNR may be entered after physician-patient or physician-family discussion, often without the patient's prior advance directive specifying it. In other settings the DNR is patient-led.

When the family disagrees with the patient #

A recurring source of distress is families who, in the moment, want resuscitation despite the patient having previously requested a DNR. The general legal position is that a valid clinical DNR order, based on the capable patient's expressed wishes, remains in force notwithstanding family preferences expressed later.^[4]

The practical buffer is the substitute decision-making framework. If the patient is incapable and the family disagrees with the standing DNR, the substitute decision-maker can request that the physician review the order. The physician retains the clinical decision but is generally expected to consider the substitute decision-maker's input.

The reverse situation — family wanting a DNR when the patient has not asked for one — is harder. A substitute decision-maker generally cannot request that resuscitation be withheld for an incapable patient who has no prior advance directive on the question, except in cases where CPR would be medically futile or not in the patient's best interests under the applicable consent statute.

Practical steps for your plan #

Three steps, in roughly the order most families find useful.

First, separate the documents in your mind. A will is a postmortem document. A personal-care POA names who decides for you. An advance directive expresses your wishes to guide that decision-maker. A clinical DNR is a paramedic-facing or chart-facing order. All four can coexist and they do different jobs.

Second, have the clinical conversation with a physician. If you want a DNR to be operative at home — to prevent paramedic CPR after a 911 call — the conversation needs to result in a physician-signed province-specific form. This is not something a lawyer can arrange. It is generally arranged through your family physician or, in palliative-care settings, through a palliative-care team.

Third, make the form physically accessible. The standard locations are on the fridge (the paramedic's first-look location in most provinces), in a hospital-go-bag, in the patient's wallet, and in the personal-care POA's possession. Multiple copies are appropriate. A DNR locked in a safety deposit box is functionally useless.

What this means for your plan #

A DNR is the operational document for a moment that may never come. Most Canadians who set one up will never need it; the families who do need it tend to be very grateful that the upstream conversations happened in advance. The other documents — the personal-care POA, the advance directive, the living will — set the table; the DNR is the meal at the moment of cardiac arrest.

When clients build their personal-care plan with It's Simple Will, the workflow prompts for the upstream documents (POA, directive) and flags the need to discuss a clinical DNR with the family physician if the user expresses resuscitation preferences. For the broader picture, our pillar on estate planning in Canada covers how the DNR fits among the other end-of-life documents.
