By-elections to the 29th Alberta Legislature

By-elections to the 29th Alberta Legislature have been held to fill vacancies in the Legislative Assembly of Alberta after the 2015 election. To date, two by-elections have been held to fill vacancies in the 29th Alberta Legislature.

The 29th Alberta Legislature was formed after the 2015 election, during which the New Democrats won their first majority government under the leadership of Rachel Notley. Three by-elections since have been in ridings which were initially won by the Progressive Conservatives, and have returned one Wildrose, one Progressive Conservative, and one United Conservative member each to the legislature. Two held in ridings initially won by Wildrose returned United Conservative members.

Calgary-Foothills

Following the Alberta Progressive Conservatives' defeat in the 2015 provincial election, outgoing premier Jim Prentice announced on election night that even though he had personally won re-election in Calgary-Foothills, he was resigning his seat in the legislature. This had the effect of voiding the election result, and necessitated the calling of a by-election to fill the seat.

The by-election to succeed him was scheduled for September 3, 2015, and was won by Prasad Panda of the Wildrose Party. Panda's victory increased the Wildrose caucus to 22 members in the Legislature, and kept the Progressive Conservatives at 9.
