The CFL training camps start in the end of May, and the actual season usually starts at the very end of June and the Grey Cup Game (Championship) is usually the 3rd week in November.
The CFL is broadcasted on America One i believe, and there are a bunch of local channels that probably broadcast games too. I believe some Comcast channels carry CFL games, or if you have satellite with Canadian Channels, it would be on TSN. You can also watch online live for $9.95 a game, or listen to the games on SIRIUS satellite radio, if you got it, or I can also tell you some local radio networks that broadcast the games too, and you can just listen over the net. Another option is to take a trip up to Canada in the summer!
