From a recent G+M article:

"Vancouver’s burgeoning tech sector has two major strikes against it when it comes to competing with Seattle and San Francisco for in-demand workers on the West Coast: sky-high property prices combined with relatively low wages"

"The report compared the average wages of a software engineer with housing and living costs in the three coastal cities and found Seattle is by far the most affordable destination".

In Vancouver, these tech professionals can expect to earn about $72,000 each year, compared with $142,000 in Seattle and $145,000 in San Francisco, according to the report. Meanwhile, the report stated Vancouver and San Francisco have median detached house prices almost double Seattle’s $803,000."
