A few practical pointers, night flying and flying VFR on top require separate ratings in Canada. You might also get some better equipment in the US, though not necessarily so. Plenty of clapped out 150s in Canada (I am Canadian and fly in Canada BTW). Used to be that spin training was required in Canada, no more (it was in my day, and I've spun every aircraft I have owned which includes: C150, PA28-140, Beech 77 Skipper and the current Beech C23 Sundowner...all cleared for spins in the appropriate category). I once chatted with a Northwest Airlines pilot on an airport shuttle bus who opined that the level of training in Canada was better, and our flying more precise as a result. Just an opinion though...and of course as a Proud Canadian, one I latched on to.
