US citizen living in Victoria here -- the west coast of Canada is pretty fantastic in many ways, but the availability of quality tech jobs takes a sharp nosedive once you leave Toronto, as far as I've been able to tell. It could be interesting if Startup Visa immigrants chose to move this direction (not only for "quality of life" reasons but also to be geographically closer to Seattle/Portland/SanFran), but I wouldn't surprised in the least if they flock to Toronto because everyone wants to belong to the larger tech scene to attract talent and connections.
