As a foreign corporation looking to carry on business in Canada through a branch office, you may:

• Register with the provincial registrars  in the province or territory for carrying on business within that province or territory. It is also necessary for the foreign corporation to obtain the approval of the provincial or territorial authorities to the business or corporate name under which the corporation will operate.
  
  
• Choose to incorporate, either at the federal or at the provincial/territorial level. If a branch office of a foreign corporation is incorporated under the Canada Business Corporations Act, then there are no different filing requirements than for other Canadian corporations.
