Since pretty much any gun is available to you since you don't have crazy import laws (I'm assuming)...
There are a few companies/brands that you'll be able to get that are great.
TM VSR-10 obviously.
There's also things like the Real Sword SVD. Good luck finding something like that in Canada but you should be able to order directly off Redwolf and such places.
STAR/ARES has a pretty good rep.
I've also heard Tanaka and Maruzen thrown around before but I'm not sure if it was positive or negative. (Warning Tanaka works has gone under IIRC due to Japan shutting them down for the revolver/real ammo thing so if you do get one make sure it doesn't break or that you can at least source replacement parts).
