Corporation key

A corporation key is a password. The corporation number along with a corporation key allows you to complete some online transactions.

A corporation key is mandatory to file an annual return and individuals with significant control information for businesses incorporated under the CBCA.

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.

Manage access to your corporation key

New access management tools Quick links are now available for your corporation on the right-hand side of the Online Filing Centre. Among other functionalities, you can link your corporation to your My ISED Account using a corporation key. Once this is done, you will no longer need to use your key when filing!

This feature greatly reduces the hassle around sharing a corporation key with members of a corporation, misplacing it and having it fall into the wrong hands.

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.
