I know nothing, sorry. Got anybody local to you that you could ask too?
I just googled "canadian composer contemporary professor" and got links to some articles. Flick through and see where people who are mentioned taught or studied. Better yet if they are still alive. If they are good enough to pop up in that sort of google search, the music programs they are associated with are probably worth a look. If one particular music program is mentioned repeatedly that's definitely a good sign.
So far I see mentions of The Royal Conservatory of Music in Toronto (3 mentions), University of British Columbia, The Conservatoire de Musique du Quebec in Montreal, University of Toronto, Wilfrid Laurier University, University of Calgary, Queen's University School of Music (highlighted as having produced many of Canada's major composers), the Schulich School of Music at McGill University...
I'm also seeing a pattern that many of these contemporary composers got their start in Canada, but then went to Europe to continue their studies with a Masters or Doctorate degree.
Google contemporary composers: http://en.wikipedia.org/wiki/Contemporary_classical_music
Find out where all the people mentioned in this article studied and teach, be it Canada, or elsewhere. (:
