I'm not an attorney and this info is only 'to the best of my knowledge in the US', so I would definitely (and absolutely recommend you) contact an attorney in the area any case would be in before doing anything, but, from what I know, time, travel expenses, etc. relating to an infringement suit may be awarded in addition to any damages from the actual infringement if 'the entity infringed upon' wins a suit in the US.
If the laws of Canada are the same and it's a 'slam dunk' you're the winner and you know the infringer can and will pay*, I would definitely consider 'going for it', but I'm not 100% sure on anything relating to this type matter, especially in Canada, so definitely, in my opinion, you should contact an attorney who has adequate knowledge to advise you and do your own due diligence before making a decision.
* I have heard from a number of people here in the US winning is one thing, but actually receiving payment may be another completely different matter.
