Wow, those are really low numbers. I'm pretty confident you can fetch very similar salaries in Montreal, and housing is 3-5 times cheaper? Or even more?
I (and about 50 of my developer coworkers) make those sort of salaries here in small-town Quebec, with significantly cheaper housing than even Montreal.
I'm sure Vancouver is a beautiful city, but comparing those salary numbers against the housing over there makes it extremely unattractive.
