Lower Mainland

The Lower Mainland, officially known as the Lower Mainland Counties Area, is a major metropolitan area in Canada, and the largest of British Columbia's three county areas by population. It consists of seven counties, and is more or less coterminous with Metro Vancouver, with Vancouver being the most populous city and urban core of the metropolitan area.

The seven counties of the Lower Mainland are coterminous with the Lower Mainland Police Area, which is under the jurisdiction of the Lower Mainland Constabulary (LMC). The seven counties together forming the Lower Mainland have a population of approximately 6.78 million, making it the most populous metropolitan area in BC and the third-most populous in Canada, after the Toronto Metropolitan Area and the Montreal Metropolitan Area.
