In Canada, trademarks are due for a renewal every 10 years from the date they are registered.
Note: Different countries and states follow different protocols. EU and the UK require the renewal date to be counted from the date it was filed rather than the date it was registered. This is due to the period between filing and registration being relatively shorter.
In comparison, since the process of registration is quite lengthy in Canada, the time from which the renewal period is counted starts when the trademark is registered, instead of when it was filed.
