Q. How long does copyright last?
In Canada, copyright generally lasts for the life of the creator plus 50 years as of December in the year that the creator dies. The length of copyright protection depends on the type of work, whether the work was created by an individual, corporation, or a federal or provincial government, the date of creation, and the date of publication.
