New Westminster is a city in the Lower Mainland region of British Columbia, Canada, and a member municipality of the Metro Vancouver Regional District. It was founded by Major-General Richard Moody as the capital of the Colony of British Columbia in 1858 and continued in that role until the Mainland and Island colonies were merged in 1866. It was the British Columbia Mainland's largest city from that year until it was passed in population by Vancouver during the first decade of the 20th century.

The Metro Vancouver Regional District (MVRD), or simply Metro Vancouver, is a Canadian political subdivision and corporate entity representing the metropolitan area of Greater Vancouver, designated by provincial legislation as one of the 28 regional districts in British Columbia. The organization was known as the Regional District of Fraser–Burrard for nearly one year upon incorporating in 1967, and as the Greater Vancouver Regional District (GVRD) from 1968 to 2017.
