I have no concrete answer, but I'm assuming Montreal is far enough away from Toronto to have the games broadcast. I'm in Cape Breton and with my basic cable I get about 65 games on The Score/Sportsnet.. and the remaining games on my Digital Cable on Raptors TV.
i've been following the raptors religiously for the past 5-6 years and its not always the easiest down in Montreal. For one thing, there's no Score on basic cable. If you live downtown, there's Peel Pub on Peel and Champ on St-laurent where you can watch games. NDG has PJs. Are you going to Concordia or Mcgill?
