Power of Attorney in Canada: Property, Personal Care and Quebec's Protection Mandate
Loading article…
A power of attorney in Canada lets someone you trust act for you if illness, an accident, or age leaves you unable to manage your money or your care. Without one, your spouse or children cannot simply step in: they may have to go to court first. Each province has its own documents, names, and signing rules, and Quebec uses a separate tool called the protection mandate. This guide is part of our retirement and estate planning hub.
The rules below were checked as of October 20, 2026, against official sources: Ontario's Substitute Decisions Act and its page on how to make a power of attorney, Québec.ca's section on the protection mandate, British Columbia's Power of Attorney Act and its page on incapacity planning, and Alberta.ca's page on the enduring power of attorney.
What a power of attorney does
A power of attorney is a legal document in which you, the grantor, name an "attorney" to act on your behalf. The attorney does not need to be a lawyer. It is usually a spouse, an adult child, a close friend, or a trust company.
There are two families of decisions. The first covers money and property: paying bills, managing investments, filing taxes, or selling a house. The second covers your health care, your housing, and your daily life. Most provinces use a separate document for each, and you can name a different person for each one.
A power of attorney only works while you are alive. At death, your will takes over and the executor, or liquidator in Quebec, becomes the person in charge.
Power of attorney for property
A power of attorney for property must say that it continues if you lose capacity, or it ends at the moment you need it most. Ontario calls this a continuing power of attorney for property. British Columbia and Alberta call it an enduring power of attorney.
In Ontario, your attorney for property can act immediately once you sign, unless the document says it starts later, for example only if you become mentally incapable. The attorney can do anything with your property that you could do yourself, except make a will. When you name two or more attorneys in Ontario, they must act together unless the document says otherwise.
In British Columbia, the document must state whether the attorney can act while you are still capable or only once you are not. Alberta's version can start immediately, on a set date, or when a specific event happens, such as a loss of capacity.
Power of attorney for personal care
The personal care document covers decisions about your medical treatment, where you live, and daily needs such as meals and clothing. In Ontario, it only applies when you cannot make the decision yourself.
The name changes by province:
- Ontario: power of attorney for personal care, which you can make from age 16
- British Columbia: representation agreement, under section 7 or section 9, plus an optional advance directive for health care instructions
- Alberta: personal directive
In British Columbia, a section 7 agreement can also cover routine financial affairs, while a section 9 agreement covers personal and health care only.
Quebec's protection mandate
Quebec does not use the term power of attorney for incapacity. It uses the protection mandate (mandat de protection), sometimes called a mandate in case of incapacity. One document can name a mandatary for your person and another for your property.
The mandatary for your person must be an individual, such as a spouse, a relative, or a friend. The mandatary for your property can be an individual or a legal person, such as a trust company. You can also name at least two replacement mandataries in case the first one dies, resigns, or becomes incapable.
How to make a protection mandate
You can make it before a notary or before two witnesses. The witnesses must be adults and capable. They must be able to confirm in writing that you have full mental capacity, and they cannot have a role in the mandate.
The Curateur public offers a free form, Mon mandat de protection, with a guide. A notary or a lawyer charges fees that vary by firm. When a notary or a lawyer prepares the mandate, they record it in their professional order's registry.
Homologation before it takes effect
This is the main difference with the rest of Canada. A protection mandate has no effect until a court homologates (approves) it. Until then, your mandatary cannot access your bank accounts to pay your bills.
The steps set out by the Government of Québec are:
- Medical and psychosocial assessments that confirm your incapacity
- Application for homologation filed with the Superior Court, by the mandatary or a lawyer or notary acting for them
- Interview of the mandator (the person who made the mandate)
- Homologation judgment
The process can take several months and involves fees, which are paid from your assets. Once the judgment is issued, the Curateur public records the mandate in its public register of representation measures.
Rules by province at a glance
The signing rules are strict. A document that does not meet them can be refused by your bank or by a hospital.
| Province | Money and property | Health and personal care | Signing rules | When it takes effect |
|---|---|---|---|---|
| Ontario | Continuing power of attorney for property (age 18+) | Power of attorney for personal care (age 16+) | 2 witnesses; listed people cannot witness; video witnessing allowed if one witness is a Law Society licensee | Property: on signing unless stated otherwise. Personal care: when you cannot decide |
| Quebec | Protection mandate, mandatary for property | Protection mandate, mandatary for the person | Before a notary, or before 2 adult and capable witnesses with no role in the mandate | Only after homologation by the court |
| British Columbia | Enduring power of attorney | Representation agreement (section 7 or 9); advance directive | Enduring power of attorney: 2 witnesses, or 1 if a lawyer or BC notary | Enduring power of attorney: date or event stated in the document |
| Alberta | Enduring power of attorney | Personal directive | No regulated form for the enduring power of attorney | Immediately, on a date, or on an event such as loss of capacity |
Who cannot witness in Ontario
Ontario's Substitute Decisions Act names the people who cannot witness either power of attorney. The same list applies to both documents:
- The attorney: or the attorney's spouse or partner
- Your spouse or partner: whatever their role in the document
- Your child: or a person you have treated as your own child
- A person under guardianship: whose property is under guardianship or who has a guardian of the person
- A minor: anyone under 18 years old
British Columbia has a similar rule. The attorney, their spouse, child, or parent, and anyone who is not an adult cannot witness an enduring power of attorney there.
How to choose your attorney
Pick someone who is organized, honest, and willing to keep records. Your attorney for property must account for every transaction made on your behalf. In Quebec, a mandatary for property must make an inventory of your assets within 60 days of homologation and render accounts as the mandate provides.
Talk to the person before you name them. Tell them where your documents are kept, which bank and investment accounts you hold, and how you would like your care handled. Name a backup in case your first choice cannot act. If you name two people for property, decide whether they act together or separately, and write it down.
Give your bank a copy once the document is in force. A clear paper trail helps, especially for accounts like a chequing account for seniors that you may want a relative to help manage.
What happens without one
Without a power of attorney for property in Ontario, your family cannot automatically make financial decisions for you. They may have to apply to court to become your guardian, and the Office of the Public Guardian and Trustee may act as a last resort. Your family can make some personal care decisions, but not all.
In Alberta, a family member or friend may have to go to court to become your trustee, which takes time and money. In Quebec, your relatives may need to ask the court for a protective measure, and the person the court appoints may not be the one you would have chosen. Planning ahead lets you choose instead.
What it costs
Government forms are free in several provinces. Ontario's power of attorney kit is free, and so is the Curateur public's protection mandate form in Quebec. British Columbia publishes free enduring power of attorney and representation agreement forms.
Online services sell powers of attorney with a will. As of October 20, 2026, Willful listed $199 for a will plus powers of attorney for property and health, and Epilogue listed $199 for a will plus incapacity documents, for one person. Lawyer and notary fees vary by firm, so ask for a written quote.
Conclusion
A power of attorney is the document you use while you are alive; a will is the one your family uses after. Sign both while you have full capacity, follow your province's witness rules to the letter, and name people who will keep good records. In Quebec, plan for the homologation step, which can take months before your mandatary can act.

Frequently asked questions about power of attorney in Canada
When does a power of attorney take effect?
It depends on the document and the province. In Ontario, a continuing power of attorney for property can be used immediately unless you write that it starts later, while a power of attorney for personal care only applies when you cannot make the decision. In British Columbia and Alberta, you choose whether the enduring power of attorney starts right away or only on incapacity. In Quebec, a protection mandate has no effect until the court homologates it. Keep your documents with your other retirement planning papers.
Can my spouse manage my bank accounts without a power of attorney?
Not automatically. Ontario's government states that your family, including your spouse, cannot simply step in to make financial decisions for you without an attorney for property. They may need to go to court to become your guardian. In Quebec, even with a signed protection mandate, your mandatary must wait for homologation. A joint account may let a spouse keep paying shared bills, but it does not give authority over accounts in your name alone. Our banking hub explains the account types you may want to review with your spouse.
Is a power of attorney from another province valid in Quebec?
The rules are set province by province, and Quebec uses its own protection mandate, which must be homologated by a court. A document signed elsewhere may raise questions when you move, so review your documents with a notary or a lawyer in your new province. The same caution applies when you move from Quebec to another province. Moving is also a good time to review your RRSP beneficiary and your will.
What is the difference between a power of attorney and a will?
A power of attorney names someone to act for you while you are alive but unable to decide. It ends at your death. A will names who receives your property and who settles your estate after death. You need both, and they can name different people. Registered accounts can also name beneficiaries directly, as our TFSA guide explains, which is another document to keep consistent with the others.
Can I name two attorneys?
Yes. In Ontario, two or more attorneys for property must act jointly unless the document says otherwise, and if one dies or resigns, the others can keep acting unless you wrote otherwise. In Quebec, you can name replacement mandataries who step in if the first one cannot act. Naming two people adds a check, but it can slow decisions if they disagree, so set out how they should work together. Keep a list of your accounts, such as your savings accounts, so they know what to manage.
How much does a power of attorney cost in Canada?
Government forms are free in Ontario, Quebec (the Curateur public form), and British Columbia. Online services listed $199 for a will plus powers of attorney or incapacity documents, as of October 20, 2026. A lawyer or a notary charges fees that vary by firm. In Quebec, also budget for homologation, which involves assessments and court fees paid from your assets when the mandate is used. Our retirement hub covers the other costs to plan for.
