yes. There is a treaty called the Madrid Protocol for trademarks and a treaty called the Patent Cooperation Treaty for patents. Last time I checked, canada was not a party to madrid but was a party to PCT.
The owner of the intellectual property can assign that intellectual property in foreign countries so they are in a better position for enforcement.
