List of British Columbia by-elections

The list of British Columbia by-elections includes every by-election held in the Canadian province of British Columbia. By-elections occur whenever there is a vacancy in the Legislative Assembly, although an imminent general election may allow the vacancy to remain until the dissolution of parliament. The most recent by-election took place on January 30, 2019, in the provincial electoral district of Nanaimo.

Causes
A by-election occurs whenever there is a vacancy in the Legislative Assembly. Vacancies can occur for the following reasons:


 * Death of a member. The last time a sitting MLA died was Fred Gingell in 1999. In addition, elected MLA's sometimes die before taking their seats. The last time this happened was in 1924 when John McKie died before the first session.
 * Resignation of a member.
 * Recall of a member. This has never happened. However, former MLA Paul Reitsma was unofficially recalled because he resigned just as a recall attempt nearly succeeded.
 * Voided results. The last time a by-election took place for this reason was in 1904. The most recent any election has come close to being voided was in 1963.
 * Expulsion from the legislature.
 * Ineligibility to sit.
 * Winning in more than one district during a general election. The last time that happened was in 1921. It has been forbidden to run in multiple districts since 1940.
 * A riding being established during a parliament. The only time a by-election took place because of this was in early 1934, in Columbia.
 * Ministerial by-election, until the 1930s an MLA's seat was declared vacant and the occupant was required to re-offer upon being appointed to Cabinet. Such by-elections often resulted in the incumbent being acclaimed.

When there is a vacancy, a by-election must be called within six months of the Chief Electoral Officer learning of it. The only exception is when a member has been recalled. In that case, a by-election must be held with 90 days.
