Yep,
Canada being part of the Commomwealth share some of the same things we do when it comes to Aviation - Rego is displayed on the lower part of the wing so it can be read from the ground, its that way here and in the UK .....
.... actually come to think of it, I think most places out side of the US display their rego on the underside of the wing, Germany and France for instance, in fact, I'm pretty sure most of Europe do it too for that matter, along with places like South Africa and Portugal...
So there ya go...
