Unlimited liability corporation
An unlimited liability corporation (ULC) within Canadian corporate law is a Canadian corporation designation, wherein shareholders are liable up to unlimited amounts for any liability, act or default of the corporation. By comparison, in most corporations, shareholders are not usually liable due to a limited liability model. ULCs can be used by American corporations for tax planning, as ULCs are treated as corporations for Canadian tax purposes but as flow-through entities for American tax purposes. Unlimited liability corporations have been abolished in Canadian corporate law in most Canadian jurisdictions, but they still exist in three provinces: Alberta, Nova Scotia, and British Columbia.
