Power of Attorney in Canada: What It Covers and When It Ends

Two documents, not one

Ontario distinguishes a continuing power of attorney for property — managing money, paying bills, dealing with a house — from a power of attorney for personal care, which covers medical and living decisions. Most provinces make a similar split under their own names; British Columbia uses a representation agreement for the care side.

You need both. A property POA does not authorise medical decisions, and a care POA does not let anyone pay your mortgage.

It ends at death. This is the mistake.

A power of attorney operates only while you are alive. The moment you die it ceases, and authority passes to the executor named in the will.

Acting under a POA after death — paying a bill, moving money, selling something — is a common and serious error. It is not a technicality; the attorney had no authority to do it.

Why you need one more than you need a will

Incapacity is more likely than sudden death, and it arrives without warning. Without a power of attorney, your family cannot manage your affairs — they must apply to court for a guardianship order, which is slow, public and expensive.

Capacity is assessed at the moment of signing. Once it is lost, a POA can no longer be made, and neither can a will.

The Islamic parallel

The classical counterpart is wakalah, an agency in which the wakil acts within the authority granted. Like a Canadian power of attorney, the agency lapses on the death of the principal.

Appointing a trustworthy agent during life is uncontroversial religiously and practically necessary in a Canadian context. What belongs in the personal care document — not in the will — is your end-of-life care preference and your burial instructions, because a will is often not opened until after burial.

Getting it right

1. Appoint an attorney for property and an attorney for personal care.
2. Name alternates for both.
3. Discuss it with them before signing.
4. Put burial and end-of-life wishes in the personal care document, and give copies to your spouse and executor.
5. Review after any marriage, divorce, or move between provinces.

Common questions

Can my attorney change my will?

No. Making or altering a will is a personal act and cannot be delegated. An attorney can, however, take actions that indirectly affect what the will distributes — such as selling a specifically gifted asset.

Does a power of attorney avoid probate?

No. It ends at death, which is precisely when probate becomes relevant.

Is a bank's own POA form enough?

It covers that institution's accounts only. A general continuing power of attorney for property is a separate, broader document.

What if I become incapable without one?

Your family must apply to court to be appointed guardian of property or of the person. It is slower and more expensive than the document you did not sign.
