That difference also existed from 1935 to 1985 and yet houses in the Vancouver region were fully affordable for local workers in that half-century period, so clearly something changed after 1985.

By the way, autumns and winters in Vancouver are NOT particularly enjoyable, and I can say that having lived for years in all three provinces (BC, Alberta and Ontario). Clouds and rain and clouds and rain, weeks on end? I dunno, that puts quite a downer on the place, though I agree the springs and late summers there are lovely.
