You need a License Proficiency check or a new Skills Test, depending on whether the two-year SEP class rating is already expired or not. See LASORS sections F1.4 and F1.5. Both need to be done by a JAA examiner. If you can find someone like that in Canada you can do it in Canada, but I would think that there's more of those around right here.
If you haven't flown for two years following your PPL exam, you should also count on a few hours training to get proficient enough to pass the test.
And considering you didn't know the answer to this question yourself, may I also suggest a bit of brush-up on the theory?
