Powers of attorney in Canada: Ontario POAs, BC and Alberta documents, and Quebec's protection mandate
How Ontario powers of attorney, BC and Alberta enduring POAs and Quebec protection mandates work, how to sign them and what happens without one.
A power of attorney lets someone you choose act for you while you are alive, and it is the document most families wish they had signed earlier. In Ontario, you need two: a continuing power of attorney for property (money, bank accounts, real estate) and a power of attorney for personal care (health care, housing, nutrition), each signed before two eligible witnesses under the Substitute Decisions Act, 1992. British Columbia uses an enduring power of attorney for finances and a representation agreement for personal and health care. Alberta uses an enduring power of attorney and a personal directive. Quebec uses one document, the protection mandate (mandat de protection), which covers both property and the person but only takes effect after it is homologated (officially approved) once you are incapable. Without these documents, your family may have to apply to a court or public guardian to be appointed, which is slower and costlier.

Ontario: two separate documents
Continuing power of attorney for property
- Capacity to sign (s. 8): you must know what property you have and its approximate value, be aware of obligations to your dependants, know that the attorney can do anything with your property you could do except make a will, and know that the attorney must account for their dealings.
- Signing (s. 10): in the presence of two witnesses, each of whom signs. These people cannot be witnesses: the attorney or the attorney's spouse or partner; your spouse or partner; your child or someone you treat as your child; a person whose property is under guardianship or who has a guardian of the person; and anyone under 18.
- "Continuing" means it keeps working after you lose capacity. It can take effect immediately or on a specified event, such as a capacity assessment.
- Since 11 December 2025, an attorney under a continuing power of attorney for property may re-make an existing beneficiary designation for a plan that is converted, renewed, replaced or transferred, such as an RRSP becoming a RRIF, so that the same beneficiary is named under the new plan (SLRA s. 51(1.1)).
Power of attorney for personal care
- Capacity (s. 47): you must understand whether the proposed attorney has a genuine concern for your welfare and appreciate that you may need them to make decisions for you. The threshold is lower than for property.
- Age: a person 16 or older can give one, and an attorney for personal care must be at least 16 (ss. 43–44).
- Signing (s. 48): two witnesses, with the same disqualifications as for property.
- It works only when you are incapable of the decision in question.
A non-compliant continuing power of attorney is not effective, though a court can declare it effective on application (s. 10(4)). Ontario's government publishes a free power of attorney kit.
If there is no POA: for property, a family member may apply to the Office of the Public Guardian and Trustee (OPGT) to replace it as statutory guardian, or to court for guardianship. For health care, the Health Care Consent Act sets a list of substitute decision-makers, starting with a spouse or partner.
British Columbia and Alberta
| British Columbia | Alberta | |
|---|---|---|
| Finances | Enduring power of attorney (Power of Attorney Act) | Enduring power of attorney (Powers of Attorney Act) |
| Personal and health care | Representation agreement (Representation Agreement Act); advance directive | Personal directive (Personal Directives Act) |
| If none | Committee appointed by court, or Public Guardian and Trustee of BC | Trustee or guardian appointed by court under the Adult Guardianship and Trusteeship Act |
Both provinces publish forms and signing rules on their government websites. The witnessing requirements, who may not witness, and whether the attorney must also sign differ between the two Acts and between the financial and personal-care documents, so follow the official form for your province exactly. A BC representation agreement can be "standard" (routine health care and personal care) or broader, with stricter conditions for the broader version.
Quebec: the protection mandate
What it covers
A protection mandate can deal with administration of your property, protection of your person (health, accommodation, well-being), or both. You name one or more mandataries and can include instructions about medical care and end-of-life wishes.
How it is made
It can be made before a notary (notarial form) or before two witnesses who have no interest in it. A notarial mandate is registered in the Chambre des notaires registry; a mandate before witnesses can be registered with the Barreau's registry if prepared by a lawyer.
Homologation
The mandate cannot be used until it is homologated: an official confirmation, after a medical and psychosocial assessment, that you are incapable and that the mandate is valid. Homologation can be done by the Superior Court or, in non-contentious cases, through the procedure before a notary. The Curateur public du Québec is notified and supervises in some respects.
The 2022 reform
On 1 November 2022, an amendment to the Civil Code and the Public Curator Act came into force. Among the changes: curatorship for adults was abolished and existing curatorships were converted to tutorship, which can now be tailored to a person's actual abilities; a new assistance measure lets an adult who is still capable choose an assistant to help with decisions; and a temporary representative can be appointed by the court for a single act. A protection mandate generally avoids tutorship unless it is insufficient.
What these documents cost (illustrative)
| Option | Typical cost drivers |
|---|---|
| Free government kit (Ontario) | Your time, and finding two qualified witnesses |
| Lawyer-drafted POAs in a will package | Often bundled; ask for a written quote |
| Quebec notarial protection mandate | Notary's fee; registration included in the notarial act |
| Court guardianship or tutorship if nothing was signed | Court applications, medical assessments, legal fees, possible security and annual accounts |
The last row is why the first three are usually worth it.
Choosing an attorney or mandatary
- Pick someone trustworthy, organised and likely to live nearby; name a substitute.
- Say whether two attorneys must act jointly (both must agree) or jointly and severally (either can act).
- Consider requiring the attorney to give a yearly account to a named person.
- Tell your bank in advance; some institutions review the document long before it is needed.
FAQ
Does a power of attorney work after death?
No. It ends at death, and the executor named in the will takes over. Your attorney must stop using your accounts.
Can my attorney change my will or beneficiaries?
An attorney cannot make a will for you. In Ontario, the 2025 amendment allows only the narrow step of re-making an existing beneficiary designation on a converted or transferred plan.
Is an Ontario POA valid in Quebec or BC?
Often in practice, but institutions in another province may ask for local formalities or a court confirmation. If you move, sign new documents under the new province's law.
