Vancouver sits on a peninsula in southwestern British Columbia, hemmed in by the Burrard Inlet to the north, the Fraser River to the south, and the Coast Mountains rising straight up behind the North Shore. It is the densest major city in Canada by design, because there is very little flat land to spread onto, so it grew upward instead of outward. About 660,000 people live in the city proper, and roughly 2.6 million in Metro Vancouver.
It was built on three things: a deep-water port, a railway terminus, and a steady flow of immigration that has never really stopped. The result is a Pacific-facing city where more than half the residents speak a language other than English at home, where the downtown core is dense and walkable, and where the seawall, the parks, and the ski hills are all closer than they have any right to be to a downtown office tower.
Daily life runs on coffee, transit, and the weather. Winters are wet and green rather than frozen white, summers are dry and warm, and people organize themselves around being outdoors whenever the sky clears. A family moving here is moving to a city that is expensive, compact, international, and unusually close to both salt water and old-growth forest.
