Most people think of ending a power of attorney as something you do on purpose — tearing up the document, or signing a new one that replaces it. But a power of attorney in Ontario can also end automatically, without anyone deciding to revoke it, the moment certain events happen.

Knowing which events those are matters for two reasons. If you're the person who granted the power of attorney, you want your planning to hold up the way you intended. If you're the attorney (or a family member relying on one), you need to know the moment your authority — or someone else's — actually stops.

This article covers the automatic endings. It doesn't cover deliberately cancelling a power of attorney, which is a separate, voluntary step.

Two Different Documents, Two Different Rules

Ontario's Substitute Decisions Act recognizes two kinds of power of attorney, and they don't end the same way:

The events below apply differently depending on which document you're looking at.

It Ends the Moment You Die

This is the one absolute rule: every power of attorney, for property or for personal care, ends automatically the instant the person who granted it dies. There's no exception for a "continuing" property document — continuing refers only to surviving your incapacity, not your death.

From the moment of death, an attorney has no further authority to act. They cannot pay bills, access accounts, or make any decision on behalf of the person who has died. Only a properly appointed estate trustee — appointed under the deceased's will or, without a will, through the court — has authority over the deceased's property from that point forward, so this is often the point where a family's next step shifts entirely.

An "Ordinary" Power of Attorney for Property Can End at the Worst Possible Time

Not every power of attorney for property is a continuing one. If a document doesn't include the wording that makes it continuing, it's an ordinary power of attorney — and an ordinary power of attorney for property automatically ends the moment the grantor becomes mentally incapable.

That's often the exact moment a family needs it most. This is why most people, when planning for the possibility of future incapacity, are advised to sign a Continuing Power of Attorney for Property rather than an ordinary one — the whole point of the "continuing" language is to keep the attorney's authority in place through incapacity, not just before it.

It Can Also Stop Working If Your Attorney Can No Longer Act

A power of attorney depends on having someone able and willing to act as attorney. Authority can effectively end — or never take effect for that attorney — if:

This is a common planning gap: people name one attorney, that attorney predeceases or becomes unable to act, and the document is left with no one who can use it — practically ending its usefulness even though the paper itself hasn't been revoked. Naming an alternate attorney is the standard way to guard against this.

What Doesn't End a Power of Attorney

A few things people often assume end a power of attorney, but don't, on their own:

Ending a power of attorney in these situations generally requires either the grantor formally revoking it while still capable, or a court application — not automatic termination.

Frequently asked questions

Does my power of attorney end automatically if I get divorced?

Divorce has a well-established automatic effect on gifts and executor appointments in a will. Whether — and how — it affects an existing power of attorney is a more fact-specific question, so if you've separated or divorced since signing one, review it with a lawyer rather than assuming it updated itself.

Can my family force my attorney to stop acting if they disagree with a decision?

Not simply by disagreeing. Ending or limiting an attorney's authority against their will generally requires either the grantor (while capable) revoking it, or a court application — disagreement alone isn't an automatic trigger.

What happens if my only named attorney dies before I do?

If no alternate attorney was named in the document, no one is left who can use it, even though the document itself was never revoked. This is why naming at least one alternate is standard advice.

Do I need a new power of attorney after I move into long-term care?

Not automatically. A validly made continuing power of attorney for property, or a personal care document already in effect, generally continues to work in a care setting — but it's worth reviewing your documents any time your circumstances change significantly.
