Power of Attorney in Ontario: Types, Uses & Limitations
A Power of Attorney (POA) gives someone else the legal authority to act on your behalf. In Ontario, there are two main types — one for your property and finances, and one for your personal care and health.
The Two Types of POA in Ontario
| Type | Covers | When It Takes Effect |
|---|---|---|
| Continuing POA for Property | Bank accounts, real estate, investments, business, taxes, debts | Immediately on signing (or a specified date) — continues even if you lose mental capacity |
| POA for Personal Care | Medical treatment, diet, housing, hygiene, safety | Only when you are incapable of making personal care decisions yourself |
Who Can Be an Attorney?
Anyone 18+ who is mentally capable can be an attorney for property. Anyone 16+ can be an attorney for personal care. You cannot name your paid caregiver as attorney for personal care (unless they are your spouse or partner). Choose someone you trust implicitly — the attorney has significant legal power.
Requirements for a Valid POA in Ontario
- Must be in writing and signed by the grantor while mentally capable.
- Must be signed in the presence of two witnesses.
- Witnesses cannot be: the attorney, the attorney's spouse, a child of the grantor, a person whose property is under guardianship, or a person under 18.
- For a Continuing POA for Property, there is additional language required stating that it continues if the grantor becomes incapable.
Duties of an Attorney
- Act in the grantor's best interests at all times.
- Keep accurate records of all transactions.
- Keep the grantor's property separate from their own.
- Consult with supportive family members and close friends (for property decisions).
- Not make gifts from the grantor's estate unless the POA expressly permits it.
Revoking a Power of Attorney
A POA can be revoked at any time while the grantor is mentally capable. To revoke:
- Prepare a written Revocation of Power of Attorney document.
- Notify the attorney in writing immediately.
- Notify all institutions (banks, registry offices) who have relied on the old POA.
- Destroy the original POA documents if possible.
What Happens Without a POA?
If you become incapable without a POA, the Office of the Public Guardian and Trustee (OPGT)or a court-appointed guardian manages your finances and/or personal care. This process is costly, slow, and removes control from your family. A POA prevents this situation entirely.
POA vs. Guardianship vs. Trustee
A POA is created voluntarily while you are capable. Guardianship is imposed by a court when you are already incapable and have no POA. A trustee manages assets held in a trust — different from a personal POA.
