The Conservative Party of British Columbia is a provincial political party in British Columbia, Canada. In the early half of the 20th century, the Conservatives competed with the British Columbia Liberal Party for power in the province. Since the 1950s however, the party has had only a minor presence, not having elected a member of the Legislative Assembly (or MLA) in a general election since 1975. In February 2023, Nechako Lakes MLA John Rustad joined the party, having left the Liberal Party in 2022. The last sitting MLA for the Conservatives had previously been John van Dongen, who briefly crossed the floor to the party in 2012 before leaving to sit as an independent. Three Conservative leaders have served as premier of British Columbia: Richard McBride, William John Bowser, and Simon Fraser Tolmie. Two Conservatives have served as deputy premier, both during a coalition government in the 1940s: Royal Maitland and Herbert Anscomb. The current party leader is Trevor Bolin.
