Almost every province and territory in Canada, including the federal jurisdiction, will require a company that is incorporated in that jurisdiction to file an annual return.
This is not the same as the company's tax return. An annual return is required by the Companies Branches of the provincial and territorial jurisdictions in Canada.
An annual return will request information about the registered office address, the mailing address, the business address, the directors, the officers and occasionally the shareholders of a company.
The provincial or territorial governments require companies registered under them to update their information on a yearly basis and most impose a small fee for the filing.
