No. Copyright in a work exists automatically when an original literary, artistic or dramatic work is created, or a performance, sound recording or broadcasting signal is created or published, so the owner is protected under copyright common law. Under Canadian copyright law, the work does not need to be registered and the symbol © is not required to appear on the work. There may not even be any reference to copyright protection. It is possible for the work to be registered under a voluntary government registration system, such as that of the Canadian Intellectual Property Office (CIPO). Registration with the Canadian Intellectual Property Office does not preclude or enhance protection. However, it is still a good idea to register your copyright and to indicate notice of copyright on your works.
