End-of-Life Decisions and DNR Orders in Ontario: The Role of Your Personal-Care Attorney

When a parent is admitted to the ICU unconscious, or a spouse is diagnosed with a condition that will eventually rob them of the ability to communicate, families face impossible questions fast. Should doctors continue aggressive treatment? Would the person want to be resuscitated? Who has the legal authority to answer? In Ontario, the framework for end of life decisions — including who speaks for you when you cannot speak for yourself — is largely governed by the Substitute Decisions Act and the Health Care Consent Act. A power of attorney for personal care (POA for personal care) is the clearest way to pre-answer these questions on your own terms.

What "End-of-Life Decisions" Means in Ontario Law

Lawyers and physicians use the phrase loosely, but it covers a defined cluster of choices:

1. Withdrawing life-sustaining treatment — stopping a ventilator, dialysis, or IV nutrition once started.
2. Withholding life-sustaining treatment — deciding not to begin a treatment in the first place.
3. Resuscitation decisions — whether CPR and related interventions should be attempted if the heart or breathing stops.
4. Palliative sedation — using medication to relieve suffering at the cost of reduced consciousness, including in the final hours of life.
5. Artificial nutrition and hydration — whether a feeding tube or IV fluids should be continued or refused.

Under the Health Care Consent Act, every one of these is a "treatment decision." A capable adult can consent to or refuse any of them. The law's job — and your personal-care attorney's job — is to carry that consent forward if you become incapable of expressing it yourself.

How a Power of Attorney for Personal Care Works at End of Life

A POA for personal care names someone you trust (your "attorney") to make health and personal-care decisions when you cannot. Incapacity is not permanent; it is assessed decision by decision. But when it applies to treatment decisions, your attorney steps into your shoes under the Health Care Consent Act as your substitute decision-maker (SDM).

The attorney's authority is not unlimited. The Substitute Decisions Act requires them to follow a hierarchy:

• First: your previously expressed capable wishes, whether written in the POA document itself or stated clearly to your attorney while you were capable.
• Second: if no prior wishes exist on the specific issue, the attorney must act in your best interests — weighing your values, your current condition, and the expected benefit and burden of treatment.

This is why it matters to talk to your attorney while you are healthy. A document that says only "I appoint Jane Doe as my attorney for personal care" does almost nothing without the conversation that fills in what you actually want.

DNR, DNAR, and AND Orders in Ontario

Do Not Resuscitate (DNR), Do Not Attempt Resuscitation (DNAR), and Allow Natural Death (AND) orders are physician-generated medical orders. A critical point that surprises many families:

Your attorney for personal care does not write a DNR order — the physician does. Your attorney's role is to consent to or refuse resuscitation on your behalf, and the physician then translates that decision into the appropriate medical order.

When a capable patient decides they do not want resuscitation attempted, they communicate that to their care team and the physician documents it. When that patient becomes incapable, the attorney or other SDM makes the decision instead — with the same legal weight as if the patient had decided themselves.

A few important realities:

• No one can force a physician to perform a resuscitation attempt that is medically futile, but disputes about what counts as "futile" are not uncommon.
• A DNR order in a hospital chart applies in that hospital. If you are transferred, or if paramedics respond to a 911 call at home, different protocols may apply. Ontario has a separate regime for community-based end-of-life orders — verify current requirements with your care team.
• Consent can be revoked at any time by a capable patient. An attorney's consent can also be revised if circumstances change.

MAID: A Critical Exception

Medical Assistance in Dying (MAID) sits in a separate legal category entirely. Under federal law as it currently stands, an attorney for personal care cannot request or consent to MAID on behalf of an incapable person. The person must be capable, at least 18 years old, and self-directing at the time of the request and at the time of the procedure. MAID requires the individual's own ongoing informed consent — it cannot be delegated to a substitute.

This means that even a meticulously drafted POA for personal care cannot authorize MAID in advance. If MAID is something you are considering for your future, the time to act on that — while you remain capable — is before incapacity arrives. As of writing, federal legislation on advance requests for MAID is an evolving area; readers should verify the current law with a lawyer or qualified health-law professional.

Palliative Care and Comfort-Focused Treatment

An attorney for personal care has full authority to request and consent to palliative care, including referrals to palliative care teams, hospice admission, and palliative sedation. This is one of the most meaningful powers the role carries. Families who have seen loved ones undergo aggressive treatment they would not have wanted often say the same thing afterward: "We didn't know we could say no."

Your attorney can say no — or say yes to comfort — on your behalf. But they will be far more confident doing so if your wishes are expressed in advance, with specificity.

When Family Members Disagree

Disagreements between family members and the named attorney — or among multiple SDMs — do happen. Ontario's process for resolving them runs through the Consent and Capacity Board, a specialized tribunal. Hospitals and care facilities also have ethics committees that can facilitate difficult conversations before a formal hearing becomes necessary.

These processes take time. Having a valid, clearly worded POA for personal care naming a single trusted attorney — rather than relying on the default SDM hierarchy under the Health Care Consent Act — reduces the risk of paralysis or conflict at the worst possible moment.

The Conversation You Should Have Now

No legal document replaces the conversation. Before you become incapable, tell your attorney:

• How you feel about life-sustaining treatment when recovery is unlikely.
• Whether you would want resuscitation attempted in various scenarios.
• How you think about quality of life versus length of life.
• Whether there are treatments you would always want, and treatments you would never want.

Write those wishes into the POA document itself where possible, or into a separate statement of wishes. The more specific you are, the less guesswork your attorney faces under pressure.
