NHL:
-Leafs
-To a lesser degree, the Western Canadian teams (Oilers more than the Flames/Canucks)
MLB:
-Blue Jays
-Expos
NBA:
-Raptors, I guess, although mostly because I want a reason to care about the playoffs.
NFL:
-No one in particular.
CFL:
-Maybe Toronto, but I like Montreal, too. I'm usually just happy if it's a good game.
I don't give 2 shits about college sports.
