I live in Vancouver a 30 minute commute from west end downtown in a four bedroom detached house in a reasonably nice neighbourhood and rent it for 1/5 of my salary. And my housing options are quite limited because I have two big dogs. One data point does not prove or disprove. If you look at average cost of living numbers compared to average developer salaries, my ratio is much closer to the picture those paint than yours.
