Authorization or Power of Attorney
You can give someone permission to represent you by granting them an authorization or power of attorney.
With an authorization, the person can view confidential information and documents we have on file for you.
With a power of attorney, the person can not only view confidential information and documents, but also act on your behalf. For example, they can negotiate with us on your behalf or ask that changes be made to your tax file.
You can appoint someone (like a spouse, family member or professional representative) as your representative by:
- using the online service for granting an authorization or power of attorney in My Account for individuals;
- sending us form MR-69-V, Authorization to Communication Information or Power of Attorney, or a handwritten letter granting an authorization or power or attorney.
Authorizations and powers of attorney are valid indefinitely, unless you specify an end date.
You can view authorizations and powers of attorney you have granted in My Account.
To appoint someone to represent you only for advance payments of the tax credit for home-support services for seniors, refer to the page entitled Power of Attorney for Advance Payments of the Tax Credit for Home-Support Services for Seniors.
Someone may have you represent them by granting you an authorization or power of attorney. You do not have to contact us or come to our offices to act on someone's behalf. If you have a general authorization or power of attorney, you can simply use the Act on Behalf of an Individual service in My Account for individuals.
If you are representing a client as part of your business, you cannot use the Act on Behalf of an Individual service in My Account for individuals. If you are professional representative, visit the Représentants professionnels page (in French only).
You can act on someone's behalf in the following cases:
- The person granted you an authorization or power of attorney using form MR-69-V, Authorization to Communication Information or Power of Attorney, or a handwritten letter.
- You have one of the following legal documents for the person:
- a succession document;
- a notarial act;
- a homologated incapacity mandate;
- You are acting under the legal mechanism known as protective supervision.
- Individuals with an authorization, power of attorney or other legal document allowing them to represent someone, such as liquidators of a succession.
- Individuals in business and professional representatives who are representing someone as a friend or family member (not professionally) and who have one of the above documents.
To use the Act on Behalf of an Individual service (available in My Account for individuals) you need to have a valid general authorization or power of attorney. You can use it to view (if you have an authorization) or change (if you have a power of attorney) information in another person's tax file.
For security reasons, you will have to provide information about the other person before using the service.
Note that authorizations and powers of attorney are valid indefinitely, unless the person granting them specifies an end date.
