Notes

1. Died in office
2. Christy Clark's Liberal government won a plurality of seats in the 2017 provincial election, but the resulting 41st Parliament of British Columbia passed a motion of no confidence against her government less than two months into her mandate. With the Opposition NDP and Green Party having made a confidence and supply agreement, the lieutenant-governor invited NDP leader John Horgan to form a government. This table counts the 2017 election as a win for both Clark and Horgan.
3. In two blocks: 1 year, 350 days & 3 years, 346 days.
4. Prior to 1903, British Columbia operated without political parties. As governments were formed by and from elected non-partisan legislators, no premier from this period was elected with an explicit mandate to govern. However, informal pro- and anti-government alliances did exist.
