The current trademark law in Canada is the Trademark Law of 1985. The registration of Canadian trademarks adopts the first-to-use principle. In Canada, a trademark is a sign used to distinguish goods or services manufactured, sold, leased or provided by different owners. Persons who intend to use the trademark and are intended to be licensed to use the trademark in Canada, persons who have already used the trademark in Canada, whose country is a member of the Paris Convention or the World Trade Organization, have registered or applied for registration of the trademark in their country and have registered the trademark anywhere The person who uses the trademark, the person who has used the trademark in any Paris Convention or World Trade Organization member and the trademark is well-known in Canada, and the successors of the above four categories can apply for trademark registration in Canada.
