From December 1, 2023, the time for Canadian trademark opposition requests and cancellation procedures for non-use of a trademark under Article 45 will be significantly reduced by 50%. This means that trademark registrants have significantly less time to prepare for trademark opposition and filing cancellation proceedings.
The table below shows the time changes for opposition and trademark revocation before and after changes to Canadian trademark law.
