Vancouver is a city in south-western British Columbia, named after Captain George Vancouver, an English explorer. It's the largest metropolitan area in western Canada and the third largest in the country. It has an ethnically diverse population. Since the 1920's it has become the busiest seaport in Canada, and exports more cargo than any other port in North America. The economy of Vancouver has diversified over time, with a growing tourism industry, and has become the third-largest film production centre in North America. More recently, Vancouver has had an expansion in high-tech industries, most notably video game design.
