By-elections to the 14th Canadian Parliament were held to elect members of the Canadian House of Commons between the 1921 federal election and the 1925 federal election. The Liberal Party of Canada led the government, which fluctuated between a minority and majority, for the 14th Canadian Parliament. The list includes Ministerial by-elections which occurred due to the requirement that Members of Parliament recontest their seats upon being appointed to Cabinet. These by-elections were almost always uncontested. This requirement was abolished in 1931.
