Can Doctors Override an Advance Directive in Manitoba?

You've signed a health care directive, distributed copies to your proxy and your doctor, and filed one in your ERIK kit on the fridge. Then the question creeps in: can a doctor just ignore it?

The short answer under Manitoba law is no — with some important caveats that are worth understanding before they matter.

What the Law Actually Says

The Health Care Directives Act (C.C.S.M. c. H27) gives your signed directive legal force. Once you lose the capacity to make or communicate medical decisions, your healthcare team is legally obligated to follow the instructions in your directive or consult the proxy you've named. This isn't optional guidance — it's a statutory obligation.

Your proxy is equally bound. They must make decisions based on your documented wishes or, if the directive doesn't cover a specific scenario, based on your known values and what they reasonably believe you would have wanted.

When a Directive Gets Set Aside

There are legitimate clinical situations where a directive's instructions don't get followed exactly as written, and they almost always come down to the same problem: vagueness.

Ambiguous language. Directives that say things like "no heroic measures" or "no extraordinary treatment" create real problems for clinical teams. What counts as heroic? Is IV antibiotics for pneumonia heroic? Is a temporary ventilator trial heroic? Paramedics and emergency physicians need precise clinical instructions, not value judgments they have to interpret under time pressure. Manitoba's Goals of Care system uses three specific treatment levels — Comfort (C), Medical (M), and Resuscitative (R) — because vague language gets set aside in favour of whatever the clinical team judges is in the patient's best interest.

Changed medical circumstances. If your directive was written before a treatment became available, or if the clinical situation is materially different from what you described, the healthcare team may need to consult your proxy about how to apply your instructions to the situation. This is rare, but it happens.

Emergency situations without access. If paramedics arrive and can't find your directive — no ERIK kit, no proxy on scene, no record in the hospital system — they default to full resuscitative care. They're not overriding your wishes; they simply don't know what your wishes are.

How to Make Your Directive Harder to Override

The strongest protection is specificity. Instead of writing "no life support," specify which interventions you do and don't want: CPR, mechanical ventilation, dialysis, artificial nutrition, blood transfusions. Reference Manitoba's Goals of Care levels directly so your language maps onto the clinical order framework that hospital teams actually use.

Name your proxy clearly and include their current contact information in the directive itself. If the clinical team can reach your proxy quickly, they have a living person who can interpret your wishes in real time — which is far more useful than a document alone.

Distribute copies widely. Your proxy, your family physician, the hospital registry, and your ERIK kit should all have the current version. The enforceability problem in practice is almost never a doctor deliberately ignoring a directive — it's a doctor who doesn't have access to one.

What If There's a Dispute?

If your proxy and the medical team disagree about what your directive means, Manitoba health authorities require formal care conferences and clinical ethics consultations to resolve the conflict. The goal is consensus based on your documented values.

If consensus fails — say, multiple family members of equal priority disagree and no proxy was ever named — the medical team or an interested party can apply to the Court of King's Bench to appoint a litigation guardian to make the decision. This is expensive, slow, and exactly the scenario a well-drafted directive with a clearly named proxy is designed to prevent.

The Real Risk Isn't Override — It's Vagueness

Most people who worry about doctors ignoring their directive would be better served worrying about whether their directive is specific enough to follow. A one-page government form with blank treatment sections doesn't give clinical teams much to work with. The more precise your instructions, the less room there is for interpretation — and the stronger your legal protection under The Health Care Directives Act.

The Manitoba Advance Directive & Living Will Kit includes a Health Care Directive Worksheet with pre-written clinical scenario options that map directly to Manitoba's Goals of Care levels, so your document speaks the same language your medical team uses.
