Best thing to do is come and attend (spectate) the BMW Trillium school happening this month (April 27/28) at Mosport GP track. You can see how it's run, talk to students, get rides with instructors and basically appreciate how the best school around operates. I've been instructing for Trillium (and numerous others) for the past 10yrs and can easily say Trillium is right there on top (one of the oldest clubs around too).
