other forums I regularly visit:
Nestcape: The Unofficial Board of the Cape Breton Screaming Eagles
(QMJHL see avatar - Go Eagles Go)
http://nestcapev.proboards40.com/ind...?board=general
and
Canadian University Society for Intercollegiate Debate (CUSID)
Debating Message Board Community for Univerisites in Canada, I generally stick to the East Coast, and Eastern Issues boards, while sometimes ducking into the Dalhousie board.

other than that, none really, forum.CalgaryPuck.com is far and away the one I post on the most frequent, and even then it's not that much really.
