Welcome aboard, but be advised that there isn't much we can do for you as a Canadian group.
Even if there are games near Windsor, you'd be better off sticking to local American events. There's a good chance you won't be allowed past the border with your gear because of our laws. The regional games and events section would be the place to check, though. http://www.airsoftcanada.com/forumdisplay.php?f=68
is where to go for that.
