In Canada, no use is required when a trademark is filed. Before your trademark registers it must be put to use. A simple Declaration of Use must be filed. One exception: when a foreign application relies on use and registration if a foreign country.
Use is mandatory to maintain your trademark after registration. It is possible to cancel a trademark for non-use if the trademark has not been in use for 3 years after registration and there has been no good reason to justify non-use.
