A corporation key is a password. The corporation number along with a corporation key allows you to complete some online transactions.
Missing your corporation key?
You can find it here:
On the 'Corporate Information Sheet', sent by email on your date of incorporation
On your email receipt from your annual return filed before September 15, 2021
If you still can't find it, you can request a new one below. Note that if you request a new corporation key, we will send it to the current registered office address by mail by the end of the next business day. Please note that mail delivery standards apply. Your previous corporation key becomes invalid as soon as we issue a new corporation key.
If your registered office address is different from the one on file, or if you have an urgent need, contact us by phone at 1-866-333-5556 (toll-free in Canada) before requesting a new key.
Manage access to your corporation key
Only share your corporation key with individuals who have the authority to file on behalf of your corporation. We recommend that you request a new key when these individuals no longer have the authority.
