No place called Sub club...but we used to have a tuning shop called Subracing. It has recently closed down as of a few days ago though. There were some issues there...dont ask. As far as Subaru clubs in Alberta though, check out
www.albertasubarclub.com
They are a good bunch of guys who can help direct you to the best place for parts and tuning in the Edmonton area.
I'd love to assist you more on the tuning part of things, but I used to go to Subracing for my tuning needs and they are no more (for now anyways).
