Vancouver has obscene housing prices because the city and the politically connected spend tens of thousands of hours fighting against any new housing, and any new supply.

The entire city and all of the NIMBYs cried about their "neighborhood character" and tried every legal trick they could to block the development: threatening to not connect it to utilities.
Vancouver literally has single family homes within half a mile of downtown! Clearly there is room for growth.
