When the dissolution filing becomes effective, the business may not carry out any activities except those appropriate to wind up and liquidate its affairs. You also must file the appropriate dissolution forms with the Department of Revenue, Department of Workforce Development and the Attorney General in order to avoid tax consequences and additional liabilities.
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.
