Q:
A: Wikipedia says: It was first settled in the 1860s as a result of immigration caused by the Fraser Canyon Gold Rush, particularly from the United States, although many immigrants did not remain after the rush. The city developed rapidly from a small lumber mill town into a metropolitan centre following the arrival of the transcontinental railway in 1887. The Port of Vancouver became internationally significant after the completion of the Panama Canal, which reduced freight rates in the 1920s and made it viable to ship export-bound prairie grain west through Vancouver.[5] It has since become the busiest seaport in Canada, and exports more cargo than any other port in North America.[6] The economy of Vancouver has diversified over time, however. Vancouver has a growing tourism industry, for example, and has become the third-largest film production centre in North America, after Los Angeles and New York City, earning it the nickname Hollywood North.[7][8][9][10][11] More recently, Vancouver has had an expansion in high-tech industries, most notably video game design.
