British Columbia is part of Canada and thus borders America. It has a city of ~3 million people (Vancouver), which is an hour's drive from Seattle (pop ~4 million) and the US west coast. It has one of the most active ports in North America and is a jumping off point for cruise ships, overseas travel to Asia and numerous other flows of people and good.
