At barely 100 square km the city of Vancouver is a tiny part of the GVRD (2700 sq km) and at 6000 people/sq km it already has the highest density in Canada. The rest of the Lower Mainland is barely 700 people per sq km. Rather than trying to pack ever more folks into Vancouver like sardines in a can, the rest of the region should be increasing density especially along the extensive (and expensive) transportation corridors.
