Does your Canadian trademark registration entitle you to protection in other countries?
At the moment, the short answer is no. Although certain common law rights may apply to protect the reputation you have established through the use of your trademark if it reaches a certain threshold, those rights are not as effective or valuable as a trademark registration for enforcing your trademark rights.
Certain advantages do exist for Canadian trademark applicants to help them obtain foreign trademark registrations through the Paris Convention for the Protection of Industrial Property. If a foreign trademark application is filed within six months of the filing date of a Canadian trademark application, a priority claim to the Canadian trademark application may be made to supersede trademark applications in that jurisdiction that were filed at a later date than the Canadian filing date.
Therefore, it may be useful for you to file trademark applications in other countries or regions where you are hoping to get your trademark protected within six months of filing your Canadian trademark application. This may allow your foreign application to take precedence over similar but later-filed applications. https://www.heerlaw.com/protecting-trademarks-abroad
