Register your Business

business name registration refers to a registration under the Business Names Act. It applies to small business owners who want to register a sole proprietorship, a partnership or an operating name (trade name) for a corporation. The name of a new business must be registered if it is different than the business owner’s legal name.

It is important to note that the Master Business License, received at the time of registration, expires after 5 years and must be renewed. The Companies and Personal Property Security Branch, Ontario Ministry of Consumer and Business Services (MCBS) does not send reminder notices. There are two types of business name registration in Ontario.
