File with the appropriate federal, state, and local governmental agencies. Depending on the business purpose of your LLC and the jurisdiction in which you organize, you may have to file additional forms relating to LLCs with certain governmental agencies.

Unlike in many other Western countries, Canadian businesses generally only have one form of incorporation available. Unlimited liability corporations can be formed in Alberta "AULC", British Columbia "BCULC" and Nova Scotia "NSULC". The aforementioned unlimited liability corporations are generally not used as operating business structures, but are instead used to create favorable tax positions for either Americans investing in Canada or vice versa. For U.S. tax purposes the ULC is classified as a disregarded entity.
