Ariel, not familiar with the Toronto area, but here's a few tips that apply in most cases: Check out any yacht clubs; they almost always have youth programs; you can also check with clubs to see if they have beer
can races (these are low-key races, usually after work). Sailors will often take on extra crew for "rail meat" (crew who basically hang on the uphill side to balance the boat out. It can be wet, but great fun. Eventually, you'll get on a boat you like (crew and skipper-wise), you'll learn a lot, and as you progress you'll get handed more responsibility. Also, check for educational programs; the USCG and the US Power Squadron both have free classes
only) that teach the basics re: rules, basic techniques, etc. Hope that helps.
