How to Revoke a Power of Attorney in Canada
Quick Answer
Yes, you can revoke a power of attorney at any time — as long as you are mentally capable. You do not need permission from your attorney, your family, or anyone else. The process requires a written revocation document, properly signed and witnessed, delivered to the attorney and all third parties (banks, healthcare providers, land registries) who relied on the original POA. Without proper notice, the former attorney may continue to act — and third parties who are unaware of the revocation may continue to honour the old POA. If you need to revoke a POA or suspect abuse, book a free consultation immediately or visit our POA revocation services page.
If you are reading this, you likely need to revoke a power of attorney — and you probably need to do it quickly. Whether you have lost trust in your attorney, your circumstances have changed, or you suspect misuse of your finances, the law gives you the right to cancel your POA at any time. But the revocation must be done correctly. An improperly executed revocation may not be legally effective, leaving your former attorney with ongoing authority over your finances, property, or personal care.
This guide covers exactly how to cancel a power of attorney in Canada: who can revoke it, the step-by-step process, what the revocation document must contain, who must be notified, what to do if you suspect abuse, and the province-specific requirements for Ontario, Alberta, BC, and other provinces. If you created your POA through our power of attorney services, we can prepare the revocation for you.
Who Can Revoke a Power of Attorney?
✅ CAN Revoke
The grantor (you): If you are mentally capable, you can revoke your POA at any time, for any reason. No permission needed.
The court: If the grantor is incapacitated, a court can remove the attorney for abuse, fraud, neglect, or failure to act in the grantor’s best interest.
Consent and Capacity Board (Ontario): Can review healthcare POA decisions and direct changes.
❌ CANNOT Revoke
Family members (on their own): A family member cannot unilaterally revoke your POA — even if they disagree with your attorney’s decisions.
The grantor (if incapacitated): If you have lost mental capacity, you cannot revoke the POA yourself — a court application is required.
Third parties: Banks, doctors, and institutions cannot revoke a POA — they can only refuse to honour it if they have reasonable grounds to doubt its validity.
Step-by-Step: How to Revoke a Power of Attorney
Review Your Existing POA
Find the original POA and note the date, the attorney’s name, the type (property or personal care), and any specific revocation procedures it contains. Some POAs include clauses about how revocation must be handled.
Prepare a Written Revocation Document
Create a revocation document that clearly states your intent to cancel the POA. It must include your full legal name, the attorney’s full name, the date of the original POA, a clear statement that you are revoking all powers granted, and the effective date of the revocation. There is no prescribed form — a clear written statement is sufficient.
Sign and Witness the Revocation
Sign the revocation document in front of witnesses — using the same witnessing requirements as the original POA in your province. In Ontario, two witnesses are required (unless one is a lawyer). The witnesses cannot be the attorney being revoked, their spouse, or their child. Date the document at signing.
Deliver the Revocation — This Is Critical
The revocation is not effective until the attorney receives actual notice. Send the revocation by registered mail with return receipt, personal delivery, or courier with proof of delivery. Simply mailing it without confirmation is not enough. The former attorney may continue to act until they receive actual notice of the revocation.
Notify All Third Parties
Send copies of the revocation to every institution or individual that relied on the original POA: banks and financial institutions, investment advisors, insurance companies, healthcare providers, long-term care facilities, the Land Registry Office (if the POA covered real estate), CRA (if the attorney filed taxes on your behalf), and any other organization that has a copy of the original POA.
Retrieve and Destroy All Copies
Ask the former attorney to return all original and copies of the POA. Mark each copy “REVOKED” with the date and your signature. Destroy the originals. As long as an unmarked copy exists, there is a risk it could be presented to a third party who is unaware of the revocation.
Create a New POA (Recommended)
If you still need someone to manage your affairs, create a new power of attorney appointing a new attorney. A new POA generally revokes all prior POAs automatically — but Ontario’s Substitute Decisions Act has a unique rule: a new Continuing POA for Property does not automatically revoke an existing one unless the new document explicitly states that it does. Always include a clause revoking all prior POAs in the new document.
Need to Revoke a POA Immediately?
Our lawyers can prepare your revocation document, ensure proper witnessing, and send notice to all relevant parties — often within 24–48 hours. Free 10-minute consultation.
When a Power of Attorney Ends Automatically
In some situations, a POA terminates without a formal revocation:
Death of the grantor. A POA ceases immediately upon the grantor’s death. The attorney no longer has any authority — the executor or estate trustee named in the will takes over.
Mental incapacity (non-enduring POA only). A general (non-enduring, non-continuing) POA terminates when the grantor loses mental capacity. An enduring/continuing POA remains valid — that is its purpose.
Expiry date. If the POA specifies an end date or an event-based termination (e.g., “upon the sale of the property at 123 Main Street”), it terminates automatically at that point.
Divorce (in some provinces). In BC, divorce automatically terminates a former spouse’s authority under the POA unless the document specifies otherwise. Other provinces vary — always review and update your POA after a divorce or separation.
Attorney resignation. The attorney can resign by giving written notice. If there is no alternate attorney named, the POA becomes inoperative — leaving the grantor without representation.
What to Do If You Suspect POA Abuse
⚠️ If you suspect your attorney is misusing your finances, acting in their own interest, or abusing their authority — act immediately.
1. Revoke the POA if you are mentally capable (follow the steps above).
2. Contact your bank immediately to freeze accounts and prevent further unauthorized transactions.
3. Consult a lawyer about seeking an accounting (a legal demand for the attorney to report on all transactions made using the POA) and potential civil action to recover misappropriated funds.
4. Report to police if theft has occurred. Misuse of a POA to steal money is a criminal offence — theft over $5,000 carries a maximum 10-year prison sentence.
5. If the grantor is incapacitated: Family members can apply to the court (Ontario Superior Court of Justice, or equivalent in other provinces) to have the attorney removed and a new guardian appointed. Contact the Office of the Public Guardian and Trustee for guidance.
Provincial Requirements for Revoking a POA
Sample Revocation Language
REVOCATION OF POWER OF ATTORNEY
I, [Your Full Legal Name], of [Your Address], hereby revoke the [Continuing Power of Attorney for Property / Power of Attorney for Personal Care / Enduring Power of Attorney] dated [Date of Original POA], which appointed [Attorney’s Full Legal Name] of [Attorney’s Address] as my attorney.
[Attorney’s Name] no longer has any authority to act on my behalf, and all authority previously granted under said power of attorney is hereby revoked, cancelled, and terminated effective immediately.
Signed at [City], in the Province of [Province], this _____ day of ______________, 20___.
This sample language is for reference only. A lawyer can prepare a revocation document tailored to your province’s requirements and ensure proper witnessing and delivery. Book a free consultation to have your revocation prepared quickly.
Common Mistakes When Revoking a POA
Not delivering the revocation to the attorney. A revocation that sits in your drawer is not effective. The attorney must receive actual notice. Use registered mail with return receipt, or personal delivery with a witness.
Forgetting to notify third parties. Even after the attorney is notified, banks, investment firms, healthcare providers, and land registries may continue to honour the old POA unless they receive the revocation. Send copies to every institution that has the original POA on file.
Improper witnessing. If the revocation is not witnessed according to your province’s requirements, it may not be legally valid. Use the same witnessing formalities as the original POA.
Not retrieving copies of the original POA. If the former attorney retains a copy, they could present it to a third party who is unaware of the revocation. Request all copies back, mark them “REVOKED,” and destroy the originals.
Ontario: assuming a new POA revokes the old one. Unlike most provinces, Ontario’s Substitute Decisions Act does not automatically revoke an existing Continuing POA for Property when a new one is created — unless the new document explicitly states that it revokes all prior POAs. Without this explicit language, you could have two valid POAs with two different attorneys.
Life Events That Should Trigger a POA Review
Even if you do not need to revoke your POA today, certain life changes should prompt a review — and potentially a new POA:
Divorce or separation: Your former spouse may still have authority under your POA. In some provinces, divorce auto-revokes spousal authority — in others, it does not. Review and update immediately after separation.
Death of your attorney: If your named attorney dies and you do not have an alternate named in the POA, you have no valid POA. Create a new one promptly.
Change in relationship or trust: Family dynamics change. If you no longer trust your attorney or your relationship has deteriorated, revoke and appoint someone new before a crisis occurs.
Moving to a new province: Your POA may not be automatically recognized in your new province. Create a new POA that complies with local requirements.
Significant change in assets: If you have acquired a business, commercial property, or significant investments since creating your POA, review whether the existing POA is broad enough to cover these new assets — or whether you need a new POA with updated authority and potentially a different attorney with the right expertise.

Frequently Asked Questions
Can a power of attorney be revoked?
Yes — as long as you are mentally capable, you can revoke your power of attorney at any time, for any reason, without permission from anyone. You must prepare a written revocation, sign it with proper witnessing, and deliver it to the attorney and all third parties who rely on the original POA.
How do I cancel a power of attorney?
Prepare a written revocation document identifying the original POA by date and attorney name, sign it with witnesses (same witnessing requirements as the original), deliver it to the attorney by registered mail or personal delivery, notify all third parties (banks, healthcare providers, land registries), and retrieve all copies of the original POA. A lawyer can complete this process quickly — book a free consultation.
Can a family member revoke a power of attorney?
Not unilaterally. Only the grantor (the person who created the POA) can revoke it — while they are mentally capable. If the grantor is incapacitated, a family member must apply to the court to have the attorney removed. The court will intervene if there is evidence of abuse, fraud, neglect, or the attorney not acting in the grantor’s best interests.
Does creating a new POA automatically cancel the old one?
In most provinces, yes — creating a new POA generally revokes prior POAs. However, Ontario is an important exception: under the Substitute Decisions Act, a new Continuing Power of Attorney for Property does not automatically revoke existing ones unless the new document explicitly states so. Always include a clause revoking all prior POAs in your new document.
What if my attorney refuses to accept the revocation?
Your attorney’s acceptance is not required. The revocation is effective once the attorney receives notice — whether they agree or not. If the attorney refuses to stop acting or refuses to return copies of the POA, consult a lawyer immediately. Continuing to act under a revoked POA may constitute theft or fraud.
Does divorce automatically revoke a POA?
In BC, divorce automatically terminates your former spouse’s authority under the POA (unless the document specifies otherwise). In other provinces, the rules vary. After any divorce or separation, review and update your POA immediately — do not assume it has been automatically revoked.
Can I revoke a POA if I am incapacitated?
No — you cannot revoke a POA if you lack mental capacity. This is why the POA was created in the first place. If an incapacitated person’s family suspects abuse, they must apply to the court to have the attorney removed and a guardian appointed. The Office of the Public Guardian and Trustee can also investigate.
Do I need a lawyer to revoke a power of attorney?
Legally, no — you can prepare a revocation document yourself. However, a lawyer ensures the revocation is properly drafted, witnessed, and delivered to all necessary parties. Given the urgency and potential consequences of an improperly executed revocation, professional help is strongly recommended — especially if abuse is suspected. Book a free consultation.
What is POA abuse and how do I report it?
POA abuse occurs when the attorney uses their authority for their own benefit rather than the grantor’s — unauthorized withdrawals, property transfers, lifestyle spending, or neglect. Report theft to police (it is a criminal offence). Contact a lawyer about seeking an accounting and civil recovery. Contact the provincial Public Guardian and Trustee. If the grantor is in a care facility, the facility may also have reporting obligations.
