Does an Ontario Power of Attorney Continue After Death? A Transition Checklist

Published October 15, 2026 · Meysami Law Professional Corp. · Ottawa

A power of attorney is lifetime planning, not estate authority. Ontario describes it as a document that appoints someone to make decisions while the grantor is alive. When the grantor dies, the estate must be dealt with under the will, applicable legislation and any court certificate. The former attorney and the estate trustee may be the same person, but they are legally distinct roles and should be documented separately.

Stop using the power of attorney after death

Do not continue signing, withdrawing money, selling property or giving instructions under the power of attorney after learning of the grantor's death. Ontario's Substitute Decisions Act lists the grantor's death as an event that terminates a continuing power of attorney for property. A power of attorney for personal care also concerns decisions made for a living person and cannot authorize post-death estate administration.

Identify the estate trustee and the source of that authority

The will may name an estate trustee, sometimes called an executor. If there is no will, the named person cannot act, or an institution requires formal proof, an application to the Superior Court of Justice may be necessary. Ontario states that the estate trustee is the person with legal authority to manage or distribute the estate; a Certificate of Appointment is commonly called probate and proves that authority in the circumstances where it is required.

Separate the final attorney accounting from estate records

An attorney for property should preserve the original power of attorney, bank and investment statements, receipts, invoices, contracts, tax records, property documents, compensation calculations and a list of transactions made during the grantor's lifetime. Record the final date on which the authority was used. The estate trustee may need these materials to understand the assets, liabilities and prior management, but estate transactions after death should be tracked in a separate estate accounting.

Notify institutions using the correct documents

Banks, pension administrators, insurers, investment firms, land registries, utilities and government programs may require a death certificate, the will, identification and sometimes a Certificate of Appointment. Requirements differ by institution and asset. Do not represent that the old power of attorney remains authority, and do not send original documents until the recipient's process and return arrangements are understood.

Protect property without treating it as personal property

Reasonable safeguarding may include securing the home, arranging appropriate insurance, protecting keys and records, caring for dependants or pets through lawful arrangements, and preventing avoidable loss. The person taking action must be clear about their authority and keep records. Do not distribute belongings, transfer funds or change ownership merely because family members agree informally or because the former attorney had access during the grantor's lifetime.

Review joint assets, beneficiary designations and debts separately

Not every asset is administered in the same way. Joint ownership, registered-plan or insurance beneficiary designations, secured debt, taxes and contractual rights may require separate analysis. Access to an account before death does not establish ownership after death. The estate trustee should gather the governing documents and obtain legal, tax or accounting advice where appropriate before paying or distributing.

Use a controlled handover checklist

Confirm the date of death; locate the will without altering it; identify the proposed estate trustee; stop attorney transactions; secure assets and records; list institutions already contacted; preserve the lifetime accounting; document any urgent safeguarding step; and ask what court certificate is required. Avoid placing account numbers, health information or family disputes in a public website form. A lawyer can advise on the transition based on the will, assets and people involved.
