Kala87....
I did some training with Professional IFR many years ago. Did their exam seminar and a couple of sim sessions. Never did any flying with them though. Found their training system to be excellent and very informative.
The Canadian Instrument Procedures and Airspace System is fairly similar to each other. You won't have too many problems, however, I have seen quite a few US pilots find the Canadian IFR training a little challenging. I believe the training in Canada goes a little further....maybe due to procedures.
Hope that helps you.
