Basketball is HUGE in Scarborough. Back when I was playing AAU ball, Scarborough was winning national championships and fielding 3-4 teams in most age brackets. I'm not sure why it wasn't mentioned...
It's not that people from Scarborough have a "hate-hockey" complex, but the majority of its residents are new immigrants and simply can't afford the costs that hockey entails. Toronto isn't a hockey town anymore - it's not neccessarily because of a paradigm shift, it's because the demographic has changed drastically. And like fancy said, there isn't much that minor hockey can do. It's not that hockey has lost its appeal, it's just becoming less accessible to more people.
