Check out the Transport Canada website. For PPL to fly C registered a/c it was just a simple validation of the overseas licence (FAA in my case) and is valid for 12 months.
Also maybe worth getting a full CAA licence if it's going to be a regular thing. You'll need a CAA medical (get it done same time as your regular medical for a nominal extra amount). Then there's just the on-line regulations test which is easily done.
Voila - and Canada has to be the best flying country there is!
