Who decides for your parent if they can't decide for themselves
Your dad falls in the kitchen. An ambulance takes him to the emergency room, and by the time you get the phone call, he's not answering questions clearly. A doctor pulls you aside and asks who's making decisions for him. You freeze, because you genuinely don't know if that's you.
Here's the short version: in Ontario, somebody already has that authority, whether your family has ever discussed it or not. It might not be who you'd expect. And it might not hold up the moment two people disagree.
You already have a decision-maker, you just don't know who
Ontario's Health Care Consent Act doesn't wait for paperwork. It hands every incapable person a ranked list of substitute decision-makers automatically. A spouse or common-law partner comes first. After that, it's children and parents together, as a group, followed by siblings, then other relatives, and eventually the Office of the Public Guardian and Trustee as a last resort.
Notice what's missing from that first tier: rank by age, by who lives closest, by who's been doing the driving to appointments for three years. None of that counts. If your dad is widowed and has four kids, all four of you sit at the same level of the list on paper, regardless of who actually knows his medications.
Where the automatic list falls apart
That's fine when everyone agrees. It stops being fine the moment they don't.
Say two siblings think Dad should go into rehab, and one thinks he should come straight home with support. Under the default hierarchy, people at the same rank are all supposed to consent together. If you can't reach agreement, the hospital can't just take the majority vote. It typically has to refer the decision to the Office of the Public Guardian and Trustee, a government body that then steps in to decide for your family. That's a stranger making the call, on a timeline set by a hospital bed that someone else needs.
This is the scenario a Power of Attorney for Personal Care exists to prevent. It lets your parent name one person, or one person with a backup, instead of leaving it to whoever happens to be in the room and whoever happens to disagree with them.
A POA doesn't decide the diagnosis, it decides who's asked
Worth being clear about what this document does and doesn't do. It doesn't tell anyone what treatment your parent should get. It doesn't skip the doctor. It just answers, in advance, the question the ER doctor asked you: who do we talk to. The actual decisions still get made in the moment, based on your parent's known wishes and the doctor's advice, by whoever holds that authority.
It's also not a diagnosis of decline. Plenty of sharp, fully capable people have one sitting in a drawer, the same way they have a will they hope not to need for twenty years. Framing it that way, as paperwork rather than a verdict, tends to go over better than framing it as "in case something happens to you," which can land as an accusation.
You don't need a lawyer's office for this
This is the part people are surprised by. In Ontario, you're allowed to prepare a Power of Attorney for Personal Care yourself, no lawyer required, under the Substitute Decisions Act. It has to be signed in front of two witnesses who aren't the person being named attorney, and there are a few other witness restrictions worth reading up on before you sign anything. Community Legal Education Ontario publishes a free guided version that walks through the whole document step by step.
That doesn't mean rushing it. It means the barrier isn't cost or paperwork complexity, so there's no good excuse to put it off until a hospital hallway forces the question.
None of this is legal advice for your specific situation, and every family's circumstances differ. If your parent's finances or health are complicated, or your siblings are already at odds, a lawyer who does elder law is worth the fee. For a lot of families, though, the free guided form and a kitchen-table conversation covers it.
This week
- Ask your parent, directly, if they've ever named a Power of Attorney for Personal Care. Most people haven't.
- If they haven't, look at the CLEO guided pathway together, even just to read through it once.
- If there's more than one sibling, have this conversation with all of them in the loop from the start. A document nobody else knew about is its own kind of landmine.
- Ask your parent what they'd actually want in a crisis, not just who should decide. That conversation matters more than the form.
- Write down where the signed document will live, and make sure the person named as attorney knows it exists before they need it.
