It is home to the provincial capital of New Westminster as well as Vancouver, British Columbia's most populous city, and thus forms the central part of Metro Vancouver, also known as the Lower Mainland. Its county seat is the city of Burnaby, the second most-populous municipality in the county, after Vancouver. In February 2020 North Fraser County had a population of 3,329,896, making it by far the most populous of the Lower Mainland's seven counties.
