A Power of Attorney (POA) is a legal document in which you (the grantor) authorize another person (the attorney) to act on your behalf. In Ontario, POAs are governed by the Substitute Decisions Act, 1992 (SDA) — not to be confused with the federal Powers of Attorney Act or common law agency concepts. Ontario recognizes two distinct types of POA for adults: the Continuing Power of Attorney for Property and the Power of Attorney for Personal Care. Both are essential components of a complete estate plan.
What Is a Continuing Power of Attorney for Property?
A Continuing Power of Attorney for Property (CPOA) authorizes your attorney to manage your financial and legal affairs. The word "continuing" is legally significant — it means the document remains valid and effective even if you later become mentally incapable. Without the "continuing" designation, a POA is automatically revoked by operation of law if you lose mental capacity, which defeats the primary purpose of having one.
The scope of authority granted under a CPOA can be broad (all financial and legal decisions) or limited to specific transactions (e.g., managing one bank account, selling a specific property while you are traveling). A general CPOA is the most common choice for estate planning purposes.
Power of Attorney for Personal Care
A Power of Attorney for Personal Care (PCPOA) authorizes your attorney to make personal care decisions on your behalf when you are incapable of making those decisions yourself. Personal care decisions include: where you live (hospital, long-term care facility, home), medical treatment, nutrition, hygiene, and safety.
Unlike the CPOA, which can take effect immediately, the PCPOA only takes effect when you are incapable of making personal care decisions. Incapacity for personal care is assessed separately from financial incapacity — you may be capable of making some personal care decisions but not others.
The PCPOA is also where you can express your wishes regarding life-sustaining treatment, organ donation, and end-of-life care — instructions that function similarly to a "living will." Your attorney under a PCPOA must follow your prior expressed wishes if they are applicable to the situation and if there is no reason to believe you would have changed your mind.
Formal Requirements Under the Substitute Decisions Act
Both types of Ontario POA must meet specific formal requirements to be valid:
- Must be in writing.
- Must be signed by the grantor (or by another person on the grantor's direction, in the grantor's presence).
- The grantor's signature (or acknowledgment) must be witnessed by two witnesses who sign in the grantor's presence.
- The witnesses must be present at the same time when the grantor signs.
Who cannot be a witness:
- The attorney named in the document.
- The attorney's spouse or partner.
- The grantor's spouse, partner, or child.
- Anyone who is under 18 years of age.
- Anyone who has a guardianship or POA over the grantor.
- For a PCPOA: anyone who provides health care or residential services to the grantor for compensation.
Capacity Requirements for Granting a POA
The grantor must have the legal capacity to grant a POA at the time of signing. For a CPOA, the grantor must understand the nature of the document, the extent of the property to be managed, and the fact that the attorney will have broad authority that can be exercised even if the grantor loses capacity.
For a PCPOA, capacity requires that the grantor understand whether the proposed attorney is likely to carry out the grantor's wishes, that the grantor appreciates that the attorney has broad authority over personal care decisions, and that the grantor understands they may set conditions on the use of the power.
If there is a question about capacity, a lawyer or capacity assessor (a health professional specifically trained under the SDA) may be required to assess and document the grantor's capacity before the document is signed.
Springing vs. Immediate Effect
A CPOA can take effect immediately upon signing, or it can be "springing" — taking effect only upon the occurrence of a specified condition, typically the grantor's incapacity as certified by one or more physicians or a capacity assessor. Springing POAs provide additional protection against unauthorized use while you remain capable, but can create delays and complications in an emergency if the condition for activation is difficult to establish quickly.
For estate planning purposes, an immediately effective CPOA is often preferred, particularly if you trust the attorney deeply. Many people choose to give the signed CPOA to their attorney with instructions to use it only when needed, relying on trust rather than formal triggering conditions.
Duties of the Attorney
An attorney under either type of POA is not a free agent — they have specific legal duties under the SDA:
- Act in the grantor's best interests and in accordance with their known wishes and values.
- Keep records of all transactions carried out under the POA (for property attorneys, detailed financial records are required).
- Keep the grantor's assets separate from their own.
- Consult with the grantor to the extent possible, even when the grantor is incapable.
- Act with honesty, integrity, and in good faith.
An attorney who breaches these duties can be held personally liable and may be required to account to the court or the Office of the Public Guardian and Trustee for their actions.
Revoking a Power of Attorney
As long as you are mentally capable, you can revoke either type of POA at any time by executing a written notice of revocation with the same formalities as the original document (signed and witnessed). You should provide notice of revocation to the attorney, any third parties relying on the POA (banks, doctors), and execute a new POA to replace it.
A CPOA is automatically revoked upon the grantor's death. It is also automatically revoked if the grantor and attorney are spouses and the marriage or partnership breaks down — though this rule is subject to court variation in some circumstances.
