You guys should check out CBC Radio 3. It is dedicated to playing independent Canadian music. There is a bit of a musical renaissance happening in Canada right now.
This thread alone named five Canadian independents: Broken Social Scene, Feist, The New Pornographers, Neko Case and Tokyo Police Club.
There's more where that came from:
