The Health Care Directives Act Manitoba: What You Need to Know

If you're trying to understand your legal rights around advance care planning in Manitoba, everything starts with one statute: The Health Care Directives Act (C.C.S.M. c. H27). This is the law that gives your written medical wishes legal force, sets the rules for who can create a directive, and defines how healthcare providers must respond when you can no longer speak for yourself.

Here's what the Act actually says — in plain language, without the legal formatting.

Who Can Make a Health Care Directive

Manitoba sets the lowest age threshold in Canada for creating a health care directive: 16 years old. Any person aged 16 or older who understands the treatment information relevant to their decisions and can appreciate the foreseeable consequences qualifies. There's a legal presumption of capacity — meaning the law assumes you're capable unless there's clear evidence to the contrary.

For context, most other Canadian provinces set the minimum age at 18 or 19. Manitoba's lower threshold means young adults transitioning out of foster care, students with chronic health conditions, or anyone aged 16-17 with serious medical needs can legally document their wishes.

What Counts as a Valid Directive

The Act deliberately avoids requiring a specific government form. Any written document that is signed and dated qualifies, as long as it expresses your medical treatment instructions or names a health care proxy (or both). You can use the free template available from the Government of Manitoba, a form from an organization like Dying With Dignity Canada, or a document you've drafted yourself.

This flexibility is intentional — the legislature wanted to avoid invalidating directives over technicalities. But it also means the quality of your directive depends entirely on how well you've drafted it. A vague document is technically valid but practically weak.

Signing and Witness Rules

If you sign the directive yourself, no witness is required under the Act. This makes Manitoba one of the simplest provinces for executing a health care directive — you can literally write, sign, and date it at your kitchen table and it's legally binding.

The witness requirement only kicks in when the maker physically cannot sign. In that case, a substitute can sign at your direction and in your presence, but this substitute signing requires one adult witness. That witness cannot be a designated proxy or a proxy's spouse.

Since 2021, Manitoba also permits remote witnessing via videoconference under the Remote Witnessing Regulation (M.R. 82/2021). The regulation imposes strict procedural requirements — video recording, government ID verification, and physical document transfers within defined timelines — but it means distance is no longer a barrier to getting a directive properly executed.

Proxy Appointments

You can name one or more health care proxies in your directive. Each proxy must be at least 18 years old and mentally competent. If you appoint multiple proxies, the Act defaults to consecutive appointment — meaning the second proxy only acts if the first one is unable or unwilling. If you want them to act jointly (making decisions together), you need to explicitly say so in the document.

Your proxy's legal obligation is to follow your documented wishes. If your directive doesn't cover the specific medical situation that arises, the proxy must decide based on your known values and what they reasonably believe you would have wanted.

How the Act Interacts with Clinical Practice

The Act creates the legal foundation, but the clinical implementation happens through the regional health authority's Goals of Care system. When your directive is activated — meaning a clinical team has determined you've lost capacity — your healthcare providers use your directive and your proxy's input to complete a Goals of Care form. That form translates your preferences into one of three active treatment levels: Comfort (C), Medical (M), or Resuscitative (R).

This is why specificity in your directive matters so much. The Act guarantees your document is legally binding, but it's the clinical detail in your instructions that determines whether the Goals of Care form accurately reflects what you actually want.

Revocation

You can revoke your directive at any time as long as you have capacity. Revocation can be done by creating a new directive that explicitly revokes the old one, by physically destroying the original, or by a clear expression of intent to revoke. If your spouse or common-law partner was appointed as the person authorized to sign a directive on your behalf, that authority is automatically revoked upon divorce — unless the document explicitly states otherwise.

Why the Act Matters for Your Planning

The Act gives you strong legal protections, but those protections are only as useful as the document you create. A detailed, specific directive that names a proxy, references Manitoba's clinical framework, and covers the medical scenarios most likely to arise gives healthcare providers a clear mandate to follow. A vague one leaves room for interpretation that may not match your intentions.
