A power of attorney is a provincial document, and every province names it, executes it, and registers it differently. This guide covers the process only: the document types provinces describe, execution and witnessing mechanics, and registration where a registry exists.

A power of attorney is a legal document in which one person, often called the donor, grantor, or adult, appoints another person, called the attorney, to act on their behalf. The attorney does not need to be a lawyer. The document is provincial: the law that creates it, the names it carries, the way it must be signed and witnessed, and whether it can be registered all depend on the province where it is made and used.
This guide covers the process only. It describes how the documents are made, signed, witnessed, stored, and registered, as the provincial pages state those mechanics. It gives no legal advice, and it gives no advice about which type of document suits a person, which attorney to name, or what powers to include. Capacity is stated only as the process gate the provincial pages describe; this guide never assesses whether a person meets it. Where a decision of that kind is needed, legal advice should be sought while the person can still make the document.
The first mistake is importing another province's vocabulary. The three provinces with the fullest published guidance use three different sets of names for the same human problem: who acts when a person cannot act for themselves.
Ontario separates the job in two. The Continuing Power of Attorney for Property covers property and finances, and it continues to operate if the maker becomes mentally incapable. The Power of Attorney for Personal Care covers health care, housing, meals, clothing, hygiene, and overall well-being. Ontario's kit contains both documents, with separate forms and guidelines for each. A general, non-continuing power of attorney for property also exists in Ontario for short-term situations; it ends if the maker loses capacity, which is the line that separates it from the continuing version.
British Columbia separates the job differently. The Enduring Power of Attorney covers financial and legal affairs, and it is governed by Parts 2 and 3 of the Power of Attorney Act. Health and personal care decisions are covered by a Representation Agreement under the Representation Agreement Act: a section 9 agreement for broader health and personal care decisions, and a section 7 agreement, which can include routine finances and legal affairs, for a person who meets the section 7 capability test but not the enduring power of attorney test. The Nidus Personal Planning Resource Centre publishes a comparison chart for the two documents, and it states plainly that the chart is a general overview, not a complete inventory.
Alberta pairs two documents as well. The Enduring Power of Attorney covers financial affairs and property. The Personal Directive, governed by the Personal Directives Act, covers personal and health care decisions and names an agent for those decisions. Alberta Health Services describes the three documents Albertans are told to consider together as a will, an enduring power of attorney, and a personal directive, each doing a different job.
Other provinces and territories use their own names — mandates, protection mandates, representation agreements, and enduring powers of attorney under their own statutes — and this guide does not list them, because those names could not be verified on official pages for those provinces. Open the attorney general or public guardian and trustee pages for the province where the document will be used, and work from the names those pages use.
Ontario publishes the clearest starting point. The Office of the Public Guardian and Trustee's page states that the free power of attorney kit is available through Publications Ontario, and the kit itself — "Powers of Attorney," ON00142E, King's Printer for Ontario, 2024 — contains forms and guidelines for the Continuing Power of Attorney for Property and the Power of Attorney for Personal Care, as two separate documents with separate forms. There is no standard form that Ontario requires; a document is valid if it meets the provincial requirements, and the kit is the province's own route to meeting them.
British Columbia takes a different approach to forms. The Nidus Resource Centre states that it does not provide forms for making an Enduring Power of Attorney, and directs people to a lawyer or notary public for that document, while it does provide forms for making a Representation Agreement. The Public Guardian and Trustee of British Columbia publishes a personal planning tools guide that introduces the Enduring Power of Attorney, the Representation Agreement, and related documents, and states that it is general information, not legal advice.
For Alberta, the Government of Alberta's Open Government catalogue lists fact sheets from the Office of the Public Guardian and Trustee covering personal directives, enduring powers of attorney, and wills, including the registration of a personal directive. Use the province's own kit, forms, or fact sheets as the drafting base. A template written for another province's statute will carry the wrong execution rules with it, and execution is where these documents most often fail.
Execution means signing, witnessing, and, where the statute requires it, the attorney's own signature. The rules differ enough between provinces that they must be read province by province, from the statute or the kit, on the day of signing.
In Ontario, the kit's forms are built around the maker signing in the presence of witnesses who also sign, with separate signature parts for the maker and the witnesses. The Substitute Decisions Act sets the capacity and execution requirements for both Ontario documents, and the kit's guidelines state them. Follow the kit's execution pages step by step, including who may and may not witness, and do not assume that a witness who is acceptable in another province is acceptable in Ontario.
In British Columbia, the Power of Attorney Act requires the adult to sign the enduring power of attorney, and the attorney named in it must also sign. The Act's witnessing section provides that only one witness is required if the witness is a lawyer or a member in good standing of the Society of Notaries Public of British Columbia, and it lists the people who must not act as a witness, including a person named as attorney, the spouse, child, or parent of a named attorney, and, with stated exceptions, an employee or agent of a named attorney. An enduring power of attorney intended to be effective for Land Title Act purposes must be executed and witnessed in accordance with that Act. Where the adult is physically incapable of signing, the Act allows another person to sign on the adult's behalf, in the adult's presence and at the adult's direction, with the signature witnessed as the section requires, and it excludes witnesses and prohibited persons from signing on the adult's behalf.
In Alberta, an enduring power of attorney must be signed by the donor in the presence of a witness, and the witness must not be the attorney or the spouse or adult interdependent partner of the donor or of the attorney. Alberta also permits remote execution by video conference, permanently, on the strict conditions described in the FAQ above: a lawyer witness who advised on the documents, real-time sight and sound, and wet-ink signatures on counterpart copies. The witness-count and exclusion details for Alberta are stated here only in the general terms the secondary summaries agree on; the current Alberta pages should be checked before signing, because those details could not be verified on an Alberta government page.
One rule holds in every province: a witness must actually witness the signing. A signature added later, a witness who was not present, or a document signed in the wrong order can leave the attorney unable to act when the document is needed. Sign in the order the form or statute sets out, in the presence the form or statute requires, and keep the signed original intact.
A power of attorney that nobody knows about helps nobody. Tell the person named as attorney that they have been named, and give them a copy or tell them where the original is kept. Tell any substitute attorney the same. Where the document covers health and personal care, give a copy to the family doctor or health care provider who will need it, and to family members who should know it exists.
Store the original in a safe place that the attorney can reach when it is needed, and keep copies with the people who will act on it. British Columbia's planning guidance suggests keeping a wallet card stating which documents have been made, where they are located, and who has been named. Alberta's personal directive guidance makes the same practical point: copies should be given to, and discussed with, the person's health professional and family members, and the document should be stored somewhere safe but easily accessible. Do not store the only original where only the maker can reach it.
Review the document when circumstances change: a new attorney, a move to another province, a marriage or divorce, or a change in the maker's wishes. Revocation and replacement follow the province's own mechanics — in British Columbia, the Nidus forms include a Notice of Revocation for an Enduring Power of Attorney and a Notice of Resignation for an attorney — and a revoked document should be withdrawn from everyone who holds a copy, so that no one acts on a superseded original.
Registration is the exception, not the rule. Ontario requires no registration for its powers of attorney. Two registries are published by their own pages, and both are described here so that readers in those provinces can use them.
In British Columbia, the Nidus Personal Planning Resource Centre operates a centralized Registry for personal planning documents, including Representation Agreements, Enduring Powers of Attorney, Advance Directives, expressions of wishes, nominations of committee, and notices of revocation. The Government of British Columbia's own page describes Nidus as a non-profit charitable organization that provides education on personal planning and operates the Registry, and it gives the Registry's contact details. Registration stores information about the document and a copy of it, so that it can be found when it is needed.
In Alberta, a personal directive can be registered with the Government of Alberta. Registration means that approved health care professionals can find out whether a personal directive exists and can reach the agent's contact information in an emergency. The fact sheet describing registration is published through Alberta's Open Government catalogue by the Office of the Public Guardian and Trustee.
Where no registry exists for the province or the document, do not invent one, and do not pay a private service that claims to register the document nationally. The mechanics that matter are the ones in Step 4: a properly executed original, people who know it exists, and copies in the right hands.
Check three things before the signing appointment. First, that the form or kit is the current one for the province where the document will be used, and that the execution pages have been read in full. Second, that the witnesses meet the province's requirements and will actually be present. Third, that the attorney named has agreed to act, or at least knows they have been named and where the document will be kept.
Get legal advice where the situation is not straightforward. The British Columbia planning guide, the Ontario kit, and the Alberta fact sheets all state, in their own words, that they are general information and not legal advice, and that a lawyer or notary should be consulted for advice about a specific situation. Capacity doubts, blended families, property in more than one province, a business to be run, or an attorney who lives outside Canada are all reasons to get that advice before signing, not after. A document made while capacity is in doubt, or executed under the wrong province's rules, may fail exactly when it is needed most.
No — and the names alone warn you. Ontario's two documents are the Continuing Power of Attorney for Property and the Power of Attorney for Personal Care. British Columbia splits the same ground differently: an Enduring Power of Attorney for financial and legal affairs, plus a Representation Agreement for health and personal care. Alberta's pair is an Enduring Power of Attorney and a Personal Directive. Because each province writes its own law and its own execution rules, a document in one province's form is not automatically in the form another province expects. Start from the pages of the province where the document will be used.
Ontario's free power of attorney kit, published by the Ministry of the Attorney General through the Office of the Public Guardian and Trustee, contains forms and guidelines for two documents. The Continuing Power of Attorney for Property covers decisions about property and finances, and it continues to operate if the person who made it becomes mentally incapable. The Power of Attorney for Personal Care covers decisions about health care, housing, and personal care. The kit treats them as separate documents with separate forms. This guide describes the kit's structure only; it gives no advice about which document suits a situation.
Under British Columbia's Power of Attorney Act, an enduring power of attorney must be signed by the adult, and the signature must be witnessed as the Act requires. The Act's witnessing section states that only one witness is required where the witness is a lawyer or a member in good standing of the Society of Notaries Public of British Columbia, and it lists the people who must not act as a witness, including a person named as attorney and close relatives of a named attorney. The attorney named in the document must also sign it. Read the current Act section before signing, because the witness rules are set by statute, not by this summary.
No national registry exists, and in most provinces registration is not required at all. Two exceptions publish their own registries. British Columbia's Nidus Personal Planning Resource Centre runs a centralized Registry covering Enduring Powers of Attorney and Representation Agreements. In Alberta, registering a personal directive with the Government of Alberta lets approved health care professionals find out whether one exists and reach the agent in an emergency. Ontario's kit imposes no registration requirement. Everywhere else, the mechanics are storage and communication: keep the original safe, and tell the attorney and the people who will need it where it is.
Remote signing is possible in Alberta, but only on tight conditions. Legislation there permits enduring powers of attorney, wills, and personal directives to be executed by two-way video conferencing, permanently rather than as a temporary pandemic measure. One witness must be an active member of the Law Society of Alberta who gave legal advice on preparing the documents. Everyone in the session must be able to see, hear, and communicate in real time. And the signatures themselves must be original wet-ink signatures on counterpart copies, compiled afterwards into one original document. Electronic or digital signatures are not permitted for these documents. Confirm the current requirements on an Alberta government or Law Society page before using the remote route.
Capacity is the process gate the provincial pages describe, and it is never assessed by this guide. A document must be made while the person making it meets the capacity standard the province's law sets; once that standard is no longer met, the document cannot be made, and the province's guardianship or substitute-decision-maker route is what the pages point to instead. In British Columbia, a person who cannot meet the enduring power of attorney capability standard may still be able to make a Representation Agreement under section 7, which has its own capability test. Get legal advice promptly where capacity is in doubt, because the window for making the document closes and does not reopen.
No witness count for Alberta is stated as a settled figure in this guide, because the secondary summaries conflict and no Alberta government execution page stating it could be verified. No registration requirement is stated for any province other than the British Columbia and Alberta registries named above, because no other province's registry page could be verified on an official page. No fee figure is stated, because no official fee page for making a power of attorney could be verified. Re-check the statute, kit, or registry page for your province on the day you sign, because the province's own page governs over this summary.
