By-elections to the 11th Canadian Parliament were held to elect members of the House of Commons of Canada between the 1908 federal election and the 1911 federal election . The Liberal Party of Canada led a majority government for the 11th Canadian Parliament .
The list includes a Ministerial by-election 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.
