British Columbia is Canada's most westerly province, and is a mountainous area whose population is mainly clustered in its southwestern corner. BC is Canada’s third-largest province after Québec and Ontario, making up 10 per cent of Canada’s land surface. British Columbia is a land of diversity and contrast within small areas. Coastal landscapes, characterized by high, snow-covered mountains rising above narrow fjords and inlets, contrast with the broad forested upland of the central interior and the plains of the northeast. The intense "Britishness" of earlier times is referred to in the province's name, which originated with Queen Victoria and was officially proclaimed in 1858.
