Power of Attorney in Ontario: Property and Personal Care

Ontario uses two distinct powers of attorney governed by the Substitute Decisions Act: a Continuing Power of Attorney for Property and a Power of Attorney for Personal Care. Together they cover financial and health decisions if you cannot make them yourself. This is general information, not legal advice — consult a lawyer in your province.

What are the two Ontario powers of attorney?

A Continuing Power of Attorney for Property lets you appoint someone to manage your finances and property. The word 'continuing' means it keeps working (or can start) after you lose mental capacity.

A Power of Attorney for Personal Care lets you appoint someone to make decisions about your health care, housing, nutrition, and personal safety if you become unable to decide for yourself.

How do you sign an Ontario power of attorney?

Both documents must be signed by you and witnessed by two people who are not your attorney, your attorney's spouse, your spouse, your child, or anyone whose property is under guardianship. Ontario has also permitted certain virtual witnessing procedures.

Your attorney for property must be at least 18; your attorney for personal care must be at least 16. Choosing someone you trust completely is the most important decision, because the authority can be broad.

When does an Ontario power of attorney take effect?

A Continuing Power of Attorney for Property can take effect as soon as it is signed, or you can specify that it only begins if you become incapable. Many people allow it to be effective immediately for convenience, trusting their attorney not to act prematurely.

A Power of Attorney for Personal Care generally only takes effect when you are found incapable of making the particular decision, so your attorney cannot override you while you still have capacity.

What happens without a power of attorney in Ontario?

If you lose capacity without a power of attorney, the Office of the Public Guardian and Trustee may step in to manage your finances, or a family member must apply to court to be appointed guardian — a slow and costly process.

Having valid powers of attorney in place avoids that uncertainty and keeps decision-making with the people you chose, not a stranger or the courts.

Can you make Ontario powers of attorney online?

Yes. Powers of attorney made with a quality online service are valid in Ontario provided they are printed, signed, and witnessed according to the Substitute Decisions Act.
