The 15th Canadian Parliament was in session from 7 January 1926, until 2 July 1926. The membership was set by the 1925 federal election on 29 October 1925, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1926 election. The Speaker was Rodolphe Lemieux. See also List of Canadian electoral districts 1924-1933 for a list of the ridings in this parliament. The unusual case of a new party taking control of the government between elections has only happened twice in Canadian history; the other occasion was in the 2nd Canadian parliament.
