I've heard really good things about Big Agnes, but until recently I've never seen them for sale in Canada. I've seen a few people virtually live out of them during the summer in Fernie BC, where I downhill bike.
It looks like you can buy them at MEC (mec.ca), which is a strong indicator of a quality product. That is to say if they are for sale at Mountain Equipment Coop, they are a solid product, and all the better if you can get it cheaper elsewhere.
In fact, I was initially going to recommend a MEC tent; I have a 4-season largish 2 person MEC tent, about 10 years old, that I have nothing but good things to say about. It was about $320 canadian back then and weighs 7 lbs. I think closest thing to it now is the 'lightfield'
