Naming just one attorney for property is common — but what happens in Ontario if that person dies or loses capacity first? Here is the gap it can create.

Most people focus on choosing the right attorney for property and stop there. Fewer stop to ask: what happens if that person — the one holding this authority — dies or becomes incapable themselves, whether before you ever need them or partway through acting for you? The answer depends heavily on one detail most people skip: whether an alternate attorney was ever named.

The Moment Your Only Attorney Can No Longer Act

If your Power of Attorney for Property names one person and no one else, and that person dies, becomes incapable, or simply becomes unwilling or unable to continue, their authority under the document simply ends. There is no automatic replacement built into the document itself — the power of attorney doesn't reach out and appoint someone new on its own.

What happens next depends entirely on your own situation at that point.

Scenario 1: You're Still Capable Yourself

If you're still capable of understanding and signing legal documents when this happens, the fix is generally straightforward: execute a new Continuing Power of Attorney for Property naming someone else. The old document's authority has already lapsed with your original attorney; a new one simply replaces it going forward.

This is the best-case version of this problem, and it's entirely avoidable through timely action. The moment you learn your named attorney can no longer serve, treating it as a to-do item rather than a someday task closes the gap quickly.

Scenario 2: You've Also Become Incapable

This is the harder version, and the reason naming an alternate matters as much as naming a primary attorney in the first place. If you're incapable yourself by the time your only attorney can no longer act, you're no longer able to sign a new power of attorney — the moment for that has passed.

Without any valid power of attorney in place, someone would generally need to apply to the court for guardianship of property in order to manage your affairs. This is a real fallback that exists precisely for situations like this one, but it is typically a more involved, more public, and more costly process than acting under a power of attorney that was already properly in place.

Why Naming an Alternate (Substitute) Attorney Matters

A power of attorney can name a substitute or alternate attorney — someone who automatically steps into the role if the first-named attorney can't or won't act. This single addition is one of the simplest ways to close the exact gap described above, and it costs nothing extra in terms of ongoing complexity; the alternate simply sits in reserve unless needed.

Naming multiple attorneys: two different structures

StructureHow it worksConsideration
Joint attorneysAll named attorneys must act together and agree on every decisionProtective, but can stall if one becomes unavailable or attorneys disagree
Joint and several attorneysAny one attorney can act alone, without the othersMore flexible and resilient, but relies more heavily on trust in each individual

Neither structure is universally "better" — the right choice depends on your family, your assets, and how much you want built-in oversight versus built-in flexibility.

Reviewing Your Document Periodically

Because this gap only becomes visible when something has already gone wrong with your original choice of attorney, periodically confirming that your named attorney, and any alternate, is still willing, able, and appropriate is worth doing — particularly after a significant life event affecting the person you named, such as their own declining health.

Frequently asked questions

Can I name more than one alternate attorney, in order?

Generally, yes — a power of attorney can be drafted to name a sequence of alternates, so that if the first-named attorney and the first alternate are both unavailable, authority passes to the next person in line, rather than the document simply running out of options.

Does the same risk apply to my Power of Attorney for Personal Care?

Yes. The same gap, and the same solution of naming an alternate, applies equally to a Power of Attorney for Personal Care, since it's a separate document covering health and personal decisions rather than property.

What if my named attorney is just unwilling to act, not dead or incapable?

The practical effect is similar: if they decline the role when it's actually needed, and no alternate was named, you're left in the same position as if they couldn't act for any other reason. This is part of why confirming willingness in advance, not just capability, matters.

Is it too late to name an alternate if I already have a power of attorney?

Not if you're still capable of signing new documents. You can revoke the existing power of attorney and execute a new one that includes an alternate, or in some cases add one through a properly executed amendment — a lawyer can advise which approach fits your situation.
