Changing contacts

If you want to add, change or cancel the contact person for your business, you will need to call the Business Window at 1-800-959-5525 or send the new information to your tax services office.

The contact person for a business can be an owner (sole proprietor, partner, director, or officer) or an employee. The contact person can register the business, make account enquiries, and update account information without written authorization.

You can name a contact person for the entire business or for certain account(s) only. The person you name in Part A of the registration form will have access to all the accounts. The person you name in parts B, C, D, and E will only have access to that specific account (GST/HST, payroll, import/export, corporate income tax).

Executors of the estate of a deceased sole proprietor are automatically considered a contact person if we receive a copy of the deceased person's last will and testament or other documents identifying who is the legal representative, and a copy of the death certificate.

Trustees and receivers are also automatically considered a contact person if we receive court issued documents to verify the named person.
