Removing or replacing a power of attorney in Ontario can feel overwhelming, especially when trust changes or the relationship shifts. The good news is that Ontario law gives you clear ways to revoke a power of attorney and appoint someone new. This guide explains each step in simple, friendly language so you feel confident and supported throughout the process.
Understanding How Powers of Attorney Work in Ontario
A power of attorney is a legal document that gives someone authority to make decisions for you. Ontario recognizes powers of attorney for personal care and for property, each with its own rules about when the authority begins and how it can be removed.
A continuing power of attorney for property stays valid even if you become mentally incapable. A non continuing power of attorney for property ends if you become incapable. A personal care power of attorney only takes effect when you cannot make your own healthcare or personal care decisions.
Because these documents affect major parts of your life such as finances, housing and medical care, it is important that you fully trust your attorney. If that changes, removing them is your right.
Reasons People Remove a Power of Attorney
People revoke powers of attorney for many personal reasons, including:
• A loss of trust
• A change in relationship
• The attorney moving away or becoming unavailable
• Concern about financial decisions
• A new partner or family member being a better fit
• The attorney wishing to resign
Your reason does not need to be explained or justified. You are the decision maker.
How to Revoke a Power of Attorney in Ontario
Revoking a power of attorney must be done correctly, so your new instructions are followed and there is no confusion among banks, medical teams or service providers.
Step 1. Prepare a Written Revocation
Ontario requires a written revocation. Your document must
• Identify the specific power of attorney you are cancelling
• Clearly state that you are revoking it
• Be signed and witnessed
If your original power of attorney was drafted with legal advice, it is helpful to have a lawyer prepare the revocation so it is clear and enforceable.

Step 2. Notify Your Current Attorney
Revoking a document does not automatically inform your attorney. You should notify them in writing and keep a copy for your records. This ensures they stop acting on your behalf immediately.
Step 3. Notify Institutions and Service Providers
Once revoked, you should notify
• Your banks
• Investment and insurance providers
• Healthcare teams
• Long term care homes
• Any organization that relied on the previous document
Most financial institutions require copies of both the revocation and your new power of attorney.
Step 4. Create a New Power of Attorney
Most people remove an attorney because they want to appoint someone new. You can create a new power of attorney at any time. A continuing power of attorney for property may take effect immediately or only upon incapacity, depending on the document wording.
A personal care power of attorney usually takes effect once you are mentally incapable. This may be determined by wording in the document or by a capacity assessment.

When the Court May Become Involved
Most revocations do not require court involvement. However, the court may step in if there are concerns about:
• Misuse of authority
• Financial mismanagement
• Family conflict
• An attorney refusing to step down
Ontario uses a process called the passing of accounts, where an attorney must provide detailed financial records and justify decisions. Several people have a right to apply for this review, including dependents, guardians, the Public Guardian and Trustee, the Children’s Lawyer and others with the court’s permission.
The court may reduce compensation, remove the attorney or appoint a guardian if necessary.
Who Can Override a Power of Attorney
A power of attorney stays valid unless
• You revoke it
• You create a new power of attorney
• A court removes the attorney
• The attorney resigns
• You pass away
Family members cannot override a valid power of attorney simply because they disagree with it. Only you or the court can make changes.
Does a Power of Attorney Expire in Ontario
A power of attorney may end if:
• You revoke it
• It includes an expiry date
• You die
• A non continuing property power of attorney ends because you became mentally incapable
• The attorney becomes unable or unwilling to act
Continuing powers of attorney for property remain valid even after incapacity. This is the purpose of creating them.

How to Change a Power of Attorney in Ontario
Changing a power of attorney in Ontario is a straightforward process, but it must be done carefully to ensure your updated instructions are legally valid. Ontario does not allow you to edit an existing document. You must prepare a new one and formally cancel the old version.
Step 1: Create a New Power of Attorney Document
Your new power of attorney should clearly outline your updated wishes, name your chosen attorney or attorneys, and explain any conditions or instructions that matter to you. You can change one document or both, depending on what needs to be updated.
Step 2: Revoke the Existing Document
Your old document remains valid until you formally revoke it. A written revocation is the safest option because it removes any uncertainty about who has authority. Your revocation should state that you are cancelling your previous power of attorney and identify the date it was created. Revoking an old document ensures there is no conflict between different versions.
Step 3: Provide Copies to the Right People
A power of attorney only works well if the people who need it have access to it. Once your new document is signed and witnessed correctly, give copies to your appointed attorney, your healthcare providers, trusted family members and any financial institutions that held your previous version. Sharing your revocation with your former attorney is also a helpful way to prevent confusion.
Step 4: Meet Ontario’s Legal Requirements
For your power of attorney to be legally enforceable, it must follow Ontario’s signing and witnessing rules under the Substitute Decisions Act. These requirements ensure the document was created freely and with full understanding. Working with a lawyer provides peace of mind that every legal detail is correct.
When Should You Update Your Power of Attorney?
Updating your power of attorney is especially important when any of the following occur in your life.
Your Relationship Changes
If you separate, divorce or experience tension with the person named in your power of attorney, updating your documents protects you from unwanted involvement.
Your Attorney Becomes Unavailable
People move, develop health issues, or simply no longer feel comfortable in the role. You can update your documents at any time to reflect the support system you currently rely on.
Your Health or Lifestyle Changes
As your health needs evolve, you may want someone who is better equipped to make medical or financial decisions. Keeping your documents current ensures the right person is in place.
You Want to Add Conditions or Clarify Your Wishes
Many people revise their documents to add specific instructions about medical care, property management or end-of-life decisions. Updating your document makes these instructions legally enforceable.
