Also check out the TWAT games in Brampton, there's one this Saturday. It's an outdoor game, BTW. Read up in the TWAT team thread to get an idea of what the TWAT's are like. As a team we are very loose and easy-going, but that doesn't mean we're not good players or serious about pwning, LOL.
Another note about Brian and TTAC3: he hosts quite a few games per month, usually he keeps a thread in the Events/Ontario section that outlines the indoor and outdoor events for that month. I suggest you take a look there regularly. And he will AV you, too!
