By-elections to the 3rd Canadian Parliament

By-elections to the 3rd Canadian Parliament were held to elect members of the House of Commons of Canada between the 1874 federal election and the 1878 federal election. The Liberal Party of Canada led a majority government for the 3rd Canadian Parliament.

Editorial cartoon from Quebec's L'opinion publique in 1874: "A Country's Remorse". The accompanying text says, "Canada mourns her sins; she is right, remorse is healthy; all these electoral court challenges have revealed a series of facts which, in the eyes of the foreigner, demeans and humiliates Canada. Hope for a better future."

The number of by-elections is notable and so is the number that were of successfully contested, mainly because courts in Canada began to take a more objective view of petitions at that time, following legal reforms on election procedure.^[1] Despite many new elections being called, many politicians were nonetheless reelected a second time.

The following 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.
