I can't say that the company is good or anything (Just because I have never bought from them or looked them up besides finding them on google), but I have found:
SHORELINE Snowboards Boots and Bindings - Burton Rome Lib-Tech Ride
evo | Skis, Snowboards, Wakeboards, and Apparel
As for what to buy, I am in the same boat as you are. Wait for someone else to help you probably and check out these sites, the Atomic site (just to see their boards and see what is best for you; there is a function that will let you do it) and Never Summer site. Both have the function. That is just what people have said are good, but you should be able to find what you are looking for there. Check out what else they have talked about and compare them to everything else through price, abilities, reviews, and overall feelings about the board.
Can't say that I helped much besides give you a few sites, but hope that helps some. They all ship to Canada.
Edit: my bad on the last one, it should be to the home page.
