List of Quebec by-elections

The list of Quebec by-elections includes every by-election held in the Canadian province of Quebec since Confederation. By-elections occur whenever there is a vacancy in the National Assembly (known as the Legislative Assembly until 1968), although an imminent general election may allow the vacancy to remain until the dissolution of parliament.

Causes

A by-election occurs whenever there is a vacancy in the Quebec legislature. Vacancies can occur for the following reasons:

• Death of a member.
• Resignation of a member.
• Voided results
• Expulsion from the legislature.
• Ineligibility to sit.
• Appointment to the Legislative Council, Quebec's appointed upper house, which was abolished in 1968.
• Appointment to the cabinet. Until 1927 incumbent members recontested their seats upon being appointed to Cabinet. These Ministerial by-elections were almost always uncontested.
