Common Advance Directive Mistakes in Manitoba (and How to Avoid Them)
A health care directive or power of attorney that looks complete on paper can be legally void because of a single procedural error. Manitoba's statutes are specific about what makes these documents valid, and families routinely discover the problems at exactly the wrong moment — during a medical crisis or when a bank refuses to honour a financial document.
Here are the mistakes that actually invalidate these documents, and how to avoid each one.
Using an Unauthorized Witness for Your Power of Attorney
This is the single most common and most consequential mistake in Manitoba advance planning. Under The Powers of Attorney Act, an Enduring Power of Attorney must be signed before a qualified professional witness from a strictly defined list: a practicing lawyer, notary public, licensed physician, police officer, judge, magistrate, or marriage commissioner.
A friend, neighbour, adult child, or bank employee does not qualify. If your EPA was witnessed by someone not on this list, the document is void. It doesn't matter how clearly it's drafted or how obviously the donor intended it — the witness requirement is a statutory formality, and failing to meet it invalidates the entire instrument.
The attorney and the attorney's spouse are also specifically barred from witnessing. This seems obvious but catches families where the spouse is the named attorney and a parent asks the couple to "just witness each other's."
Forgetting the Enduring Clause
A standard power of attorney in Manitoba terminates the moment the donor loses mental capacity. To create a document that survives incapacity — which is the entire point for most families — the document must explicitly include an "enduring clause." The exact phrasing varies, but it needs to clearly state that the attorney's authority continues despite the donor's subsequent mental incapacity.
Without this clause, the power of attorney lapses precisely when the family needs it most. The attorney discovers they can no longer access bank accounts, manage property, or pay bills on behalf of the incapacitated donor. The only remedy at that point is a court-ordered committeeship — a process that typically costs $3,000 to $5,000 in legal fees and takes months to complete.
Writing Vague Treatment Instructions
A health care directive that says "no heroic measures" or "no extraordinary treatment" gives clinical teams almost nothing to work with. These phrases have no clinical definition. What counts as heroic? Is IV antibiotics heroic? Is a temporary ventilator trial heroic? Paramedics and emergency physicians can't act on value judgments — they need specific instructions.
Manitoba's clinical system uses three Goals of Care levels: Comfort (C), Medical (M), and Resuscitative (R). Directives that reference these levels and specify which interventions you accept or refuse in concrete scenarios give healthcare teams a clear mandate. Directives that rely on subjective language leave room for interpretation that may not match your actual preferences.

Having a Proxy Sign Without a Witness
Under The Health Care Directives Act, if you sign your own health care directive, no witness is needed at all. But if you physically cannot sign and someone else signs on your behalf at your direction, that substitute signing requires an adult witness who cannot be a designated proxy or a proxy's spouse.
Families sometimes skip the witness when a substitute signs, thinking the rule is the same as self-signing. It isn't. A directive signed by a substitute without a proper witness is vulnerable to challenge.
Storing the Directive Where No One Can Find It
A directive locked in a safe deposit box is functionally worthless during a medical emergency. Banks are closed on evenings, weekends, and holidays. Your proxy may not have box access. Paramedics won't know it exists.
Your directive needs to be in your ERIK kit on the refrigerator, with your family physician, in the hospital registry, and in the hands of every named proxy. A document that can't be produced within minutes of a crisis isn't providing protection — it's providing the illusion of protection.
Failing to Revoke Old Versions
When you update your directive, every previous copy still in circulation creates a risk. If your family doctor has version one and the hospital has version two, the clinical team may act on outdated instructions. After any update, retrieve and destroy all old copies, provide the new version to every holder, and ask your healthcare team to mark any previous Goals of Care forms in your medical file as "NO LONGER IN EFFECT."
Assuming a Health Care Directive Covers Finances
A health care directive covers medical decisions only. It does not give your proxy authority over your bank accounts, property, or financial affairs. For that, you need a separate Enduring Power of Attorney. Families who discover this distinction during a crisis — when a parent has lost capacity and the bank won't release funds — face the committeeship process with all its cost and delay.
Build It Right the First Time
The Manitoba Advance Directive & Living Will Kit includes witness checklists that walk you through the statutory requirements for both health care directives and EPAs, a Goals of Care Reference Card for translating your wishes into clinical language, and a Document Distribution Tracker to prevent orphaned copies. Getting these details right the first time is dramatically cheaper and faster than fixing them after the fact.
