Not mentioned here, is cost of living mobility.

Vancouver has the highest costs to purchase a home vis a vis income of any city in North America, and third highest in the world.

It's adjoining cities are no better.

Meanwhile the rental vacancy rate is well under one percent, and rents are climbing in the double digits.  Even once affordable condos are on a double digit price trajectory.

So what happens when Canada's third largest city is no longer affordable to youth and working families? What happens when employers (including the tech industry) say they face difficulties attracting skilled workers?

This is the scenario playing out right now.

Income mobility?  It is not just the emptying out of rural areas to the urban that should challenge our government.
