Powers of Attorney in Ontario: Property and Personal Care

A will deals with what happens to your assets after you die. But what happens if you are alive and simply unable to make decisions for yourself — because of a stroke, a car accident, advancing dementia, or any other condition that affects your mental capacity?

That is exactly the situation a power of attorney is designed for. In Ontario, there are two distinct documents, each with a different scope: one for your finances and property, the other for your personal care and medical decisions. Most adults should have both, yet powers of attorney are far less commonly prepared than wills.

The Legal Framework: The Substitute Decisions Act

Ontario's Substitute Decisions Act (SDA) governs powers of attorney for property and personal care. The SDA sets out how these documents are created, who can make them, what authority they grant, and what happens if someone loses capacity without having them in place.

Understanding the SDA framework helps explain why these documents matter — and what the consequences of not having them can be.

Power of Attorney for Property

What It Covers

A Continuing Power of Attorney for Property (CPOAP) authorizes a person you choose — called your attorney (note: in this context, "attorney" means your appointed representative, not a lawyer) — to manage your financial affairs. This includes:

• Banking and investments.
• Paying bills, managing household expenses.
• Buying or selling property, including real estate.
• Filing tax returns and managing government benefits.
• Operating a business you own.

The word "continuing" is significant: it means the document remains valid even if you lose mental capacity. A non-continuing power of attorney for property terminates upon incapacity — which makes it far less useful for the situations it is most needed in.

When It Takes Effect

You can choose when your CPOAP takes effect:

• Immediately upon signing: Your attorney can act right away, even while you have capacity. This is useful if you want someone to help manage your affairs or you anticipate periods of unavailability (for example, extended travel).
• Upon incapacity only: Also called a "springing" power of attorney. The attorney cannot act until incapacity is established, which usually requires a medical assessment.

Each approach has trade-offs. An immediately effective CPOAP gives broader authority from the start; a springing CPOAP limits the attorney's authority until needed but introduces a verification step at a moment when things may already be urgent.

Safeguards on the Attorney

An attorney for property owes fiduciary duties to the grantor (the person who made the power of attorney). They must:

• Act in the grantor's best interests.
• Keep grantor's property separate from their own.
• Keep records of all transactions.
• Act only within the scope of the authority granted.

The SDA also allows you to include specific conditions, restrictions, or instructions in the document — for example, restricting the attorney from selling your home without additional steps.

Power of Attorney for Personal Care

What It Covers

A Power of Attorney for Personal Care (POAPC) authorizes your chosen attorney to make personal decisions on your behalf when you are incapable of making them yourself. Personal decisions include:

• Medical treatment and healthcare — including consenting to or refusing treatments and procedures.
• Where you live (home, assisted living, hospital).
• Diet, clothing, and hygiene.
• Safety and shelter.

Unlike a property power of attorney, a personal care POA does not take effect until you actually lack capacity to make the specific decision in question. Capacity is decision-specific — a person may have capacity to decide what to eat but not to consent to surgery.

The Role of the Personal Care Attorney

Your personal care attorney must follow any wishes you expressed while capable, to the extent known. This makes it critically important to have clear conversations with your attorney about your values, healthcare preferences, and what you would and would not want in various medical scenarios. If your wishes are not known, the attorney must act in your best interests.

A personal care POA can be paired with a separate document called an advance care directive or living will, which records your specific instructions about medical treatment. While these documents are not legally binding in the same way, they provide important guidance to your attorney and healthcare providers.

Choosing Your Attorneys

Separate or Same Person?

You can appoint the same person as both your property attorney and your personal care attorney, or different people. Many people appoint the same trusted person for both. In some cases, it makes sense to separate the roles — for example, a financially sophisticated sibling for property, and a spouse or close friend who knows your personal values for personal care.

What to Look for

• Trustworthiness and judgment: These are the most important qualities. Your attorney will have significant authority over your life.
• Availability: Your attorney must be reachable and willing to act when needed. This may be sudden and without warning.
• Willingness to follow your wishes: Choose someone who will respect your stated preferences, even if they personally disagree with your choices.
• Geographic accessibility: For property matters, proximity helps. For personal care, being locally available in a medical crisis matters.

Naming a Substitute Attorney

As with executors, always name a substitute attorney. If your first-choice attorney is unavailable, has died, or is unwilling to act when the time comes, your document is still effective through your named substitute.

What Happens Without These Documents

If you lose capacity without a valid power of attorney for property, the Office of the Public Guardian and Trustee (OPGT) — a provincial government office — automatically becomes your statutory guardian of property until a court or other process appoints someone. That person is typically a family member who must apply through the Consent and Capacity Board or the court, a process that is time-consuming, expensive, and emotionally draining.

Without a personal care POA, healthcare decisions follow a ranked hierarchy of substitute decision-makers set out in the SDA (spouse or partner, children, parents, siblings, in order). The right person may end up being legally authorized, but not necessarily the person you would have chosen — and disputes within that hierarchy are possible.

Validity Requirements Under the SDA

To be valid, a power of attorney for property or personal care in Ontario must be:

• In writing and signed by the grantor.
• Signed in the presence of two witnesses.
• The grantor must have capacity at the time of signing.

Certain people cannot serve as witnesses: the attorney or their spouse, the grantor's spouse or partner, a child of the grantor, or a person whose benefit the document confers. A witness who cannot legally serve can invalidate the document.
