At the present time the Canadian trademark, once registered pursuant to the Trademarks Act, remains registered for 10 years from the date of registration or renewal. A Canadian trademark registration can be renewed indefinitely, 10 years at a time, so long as the trademark is still in use in commerce. Terms and registration validity rules vary from country to country. As you expand the geographic scope of your trademark coverage, monitoring registration terms becomes more difficult – this is something we can help with if you need a hand.
