First of all, none of the bikes you've listed are made in Canada. Kona isn't a Canadian company, Rockies is now owned by Procycles, they have gone downhill. I would avoid Brodie like a plague.
Devinci Tosca and Norco CCX are decent, though I wouldn't buy them. Norco is based in Coquitlam, so any problem they should be able to fix it up. Kona Jake the Snake is the most versatile of the bunch you've listed. Beware of $1500 just for the ticket price, you'll jump so far past that once you add tax, pedals, shoes, helmets, tools, etc.

A good choice if you know how to fit a bike because the quality of parts you get with titanium frame for that price is phenomenal.

I don't like to shill BD, but this is also a really good choice because the components you find on this bike is comparable to those over $2000 in Canadian LBS. Have it shipped using a shipping service such as
