Power of Attorney for Personal Care in Ontario: Who Decides Your Medical Care If You Cannot
Quick answer
- A power of attorney for personal care is a legal document under Ontario's Substitute Decisions Act, 1992, in which a capable person names an attorney to make personal care decisions on their behalf if they later become mentally incapable of doing it themselves.
- As defined in the Act, personal care covers six areas: health care, nutrition, shelter, clothing, hygiene, and safety.
- This is distinct from a power of attorney for property, which has a different capacity test, a different minimum age, and a different starting point.
- A personal care document requires a person to be 16 years old or older and may generally take effect only once the grantor is incapable of the decision.
- A property document, meanwhile, carries a higher age threshold and may apply immediately unless it says otherwise.
- Without a personal care document, Ontario's Health Care Consent Act, 1996 provides a ranked default list of substitute decision-makers, meaning family members or public officials can make care choices by law rather than by choice.
Why Families Find Out Too Late
Most people encounter this document for the first time in a hospital corridor. A parent has had a stroke, a consent form is on a clipboard, and a nurse asks who has the authority to decide. Someone says "I'm her daughter," and learns that being her daughter answers only part of it.
Ontario law does not leave that moment unresolved. A system exists, and it runs whether or not a family has planned for it. What planning changes is who steps into the role, and how much that person knows about your preferred care choices.
A power of attorney for personal care is how you choose. Without one, the choice follows a list written into provincial legislation.
Start Here: Which of These Describes You
Three situations bring people to this page, and the useful answer differs for each.
You are capable and planning ahead
You may grant a power of attorney for personal care now, name alternates, and record specific care instructions. You have the most control in this situation.
You have been named as someone's attorney
Your authority typically sits dormant and may generally only be used once that person is incapable of making the decision in front of you.
Someone close to you may already be incapable
A new document may no longer be possible, and court-appointed guardianship may be the remaining route. Our wills and estates lawyers can help you work out where things stand.

Which Path Applies to You
Three situations bring people to this question, and the useful answer differs for each.
AYou are capable and planning ahead
A power of attorney for personal care may be granted now, alternates may be named, and instructions about the care you want may be recorded.
BYou have been named as someone’s attorney
Your authority typically sits dormant. It may generally only be used once that person is incapable of the decision in front of you.
CSomeone close to you may already be incapable
A new document may no longer be possible. The Health Care Consent Act, 1996 list may already apply, and court-appointed guardianship of the person may be the remaining route.

What "Personal Care" Actually Covers in Ontario Law
There are two terms that require a clear definition. The grantor signs the document and gives the authority away. The attorney receives it, and does not need to be a lawyer. It may be your spouse, adult child, sibling, or trusted friend.
Capacity means mental capacity, and Ontario law treats it as specific to each decision.
Personal Care Versus Property: Two Documents, Not One
The capacity test is not the same. To grant a power of attorney for property, a person typically needs a working grasp of their assets and value, their obligations to dependants, the attorney's authority and duty to account, and the risk that property may lose value or the authority be misused. The test for personal care is lower: understanding whether the person named has a genuine concern for your welfare, and appreciating that they may need to make personal care decisions for you.
The starting points differ too. A property document is effective immediately if it says nothing about when it begins. A personal care document, meanwhile, generally remains inactive until you are incapable of the decision being made.

Personal Care Compared With Property
Two separate documents under the same Act, with different ages, different capacity tests, and different starting points.
| Feature | Personal care | Property |
|---|---|---|
| Minimum age to grant it | 16 or older | 18 or older |
| Capacity test to grant it | Understanding whether the person named has a genuine concern for your welfare, and appreciating that they may need to make personal care decisions for you | A broader test covering what you own and roughly its value, obligations to dependants, the attorney’s authority and duty to account, and the risk that property may lose value or the authority be misused |
| What it covers | Health care, nutrition, shelter, clothing, hygiene, and safety | Financial and property decisions. It does not extend to making a will |
| When it may be used | Generally only once you are incapable of the decision being made | Immediately, unless the document says otherwise |
| Minimum age of the person named | 16 or older | 18 or older |
| Witnesses required | Two, with the same excluded-witness rules | Two, with the same excluded-witness rules |

What Happens if You Never Make One
The list is automatic, and already applies to every Ontarian without a document.
Many assume a spouse simply decides. A spouse does sit high on the list, though a court-appointed guardian or a named attorney ranks above one. Where several people share a rank, such as three adult children, they typically all need to agree, and where they cannot, the Office of the Public Guardian and Trustee may be asked to step in.
Being on the list is not enough on its own. A person generally needs to be capable of the decision, be at least 16 years old unless they are the incapable person's parent, not prohibited by a court order or separation agreement, available, and willing. The same gap appears elsewhere, as our guide to what happens when there is no will explains.

Ontario’s Ranked List of Substitute Decision-Makers
Where no power of attorney for personal care exists, this ranked default list applies to treatment decisions. Health practitioners follow the order until someone qualifies.
Where nobody on the list qualifies, or equally ranked people cannot agree, the Office of the Public Guardian and Trustee may be asked to make the decision.
A person on this list also has to meet all of these
- ▪Capable with respect to the treatment
- ▪At least 16 years old, unless they are the incapable person’s parent
- ▪Not prohibited by a court order or separation agreement
- ▪Available
- ▪Willing to take on the responsibility

Is a "Living Will" the Same Thing?
These phrases travel here from American media and from websites that sell forms, so almost everyone arrives with them in mind.
Instructions still matter. Where a document contains specific instructions, the attorney typically must follow them unless doing so is impossible. Where it does not, the attorney looks to wishes you expressed while capable, whether spoken or written. Failing that, the attorney is expected to decide in your best interests, weighing your values, your quality of life, and the benefits against the risks.
Whether an already-signed document does what its author intended is a fact-specific question worth reviewing with a lawyer.
Who May Grant One, and Who May Be Named
That restriction reduces conflicts of interest, and catches people by surprise. A paid caregiver, retirement residence staff member, or support worker generally may not be named, unless that person is the grantor's spouse, partner, or relative.
The threshold to grant the document sits below the threshold for making care decisions. Someone no longer able to make their own personal care decisions may still be capable of naming an attorney.
Multiple attorneys may be named, alternates may be added, and authority may be divided between housing and health care.
How to Put One in Place, Step by Step
-
1
Choose the person Confirm they are at least 16 years old and not disqualified as a paid provider of your care, and ask whether they are willing, as nobody is obliged to accept the role.
-
2
Have the conversation before anything is drafted The document names a decision-maker. The conversation is what allows that person to decide as you would have.
-
3
Decide what goes in it Consider which instructions to include, whether to name alternates, and whether to divide authority.
-
4
Sign it properly Two witnesses are required, and certain people may not witness: the attorney and the attorney's spouse or partner, your own spouse or partner, your child or a person you have treated as your child, a person under guardianship, and anyone under 18.
-
5
Store it where it may be found quickly A document locked in a safety deposit box on a Sunday evening helps nobody. Incapacity planning sits alongside your wider wills and estates plan.

Putting a Personal Care Power of Attorney in Place
Five steps, in order. A lawyer is not legally required, though one may help with instructions, alternates, and witnessing.
Choose the person
Confirm they are at least 16 years old and not disqualified as a paid provider of your care, and ask whether they are willing.
Have the conversation
Talk about your values and the care you would want before anything is drafted.
Decide what goes in it
Consider which instructions to include, whether to name alternates, and whether to divide authority.
Sign it properly
Two witnesses are required, and certain people may not witness.
Store it where it may be found
Give copies to the people who may need them. A document nobody can reach may not help.

Common Mistakes People Make
- ▪Assuming the property document covers health care. It does not, and many people hold only one of the two and falsely assume complete coverage.
- ▪Naming someone without discussing values. An attorney who has never heard you describe the care you want is left guessing at the hardest moment.
- ▪Naming a paid caregiver. The person paid to provide your care generally may not serve unless they are your spouse, partner, or relative.
- ▪Naming no alternate. A first choice may be unavailable, unwell, or unwilling when the time comes.
- ▪Assuming it works after death. A power of attorney ends at death, and the estate passes to the estate trustee. Our explanation of probate in Ontario covers what follows.
