Inhave no knowledge of training north of the border so I won't pretend like I know anything! All I'd say is, to get started studying now, rather than later, even if you just begin with Air Law as well as your Class 2 medical as this will hinder you as you progress and you don't want to be spending more time doing circuits or early nav trips, then move onto Comms and Navigation, but if people have a different opinion I'd be willing to listen to their points of view!
Cheers, Jim
