FAA TO TCCA Conversion
Hi, I also used pilottraining.ca and bought the course for $100 CAD. I also purchased a copy of the TC AIM which I think you can get from the TC website or amazon.com.
I passed with a pretty high mark and was happy with the course. I did some back up study with the TC AIM. As far as how much prep you do, in my opinion you can never do too much. Especially if you plan to fly in Canadian Airspace. Luckily it's not that much different from the US. Just a few differences in things like Airspace classification and altimter setting regions up North.
Good luck!
