Keep your eyes on Martin Swiss,
http://www.martinswiss.net/en/ They organize a cross training schedule when the season gets closer. They are a very good shop for cyclocross as well.
You can also check out
http://velobosco.tripod.com/ , not too far from town & one of the fellows said it's a nice little series on Saturdays!
If you don't mind travelling a bit more,
http://www.ottawabicycleclub.ca/cyclocross in/around Ottawa is a great series. More of a European type affair with the wide open courses vs the Quebec scene which can turn into mountain cross with all the single track.
See you guys out there!
