45th Canadian federal election

The 45th Canadian federal election will take place on or before October 20, 2025, to elect members of the House of Commons to the 45th Canadian Parliament. The date of the vote is determined by the fixed-date provisions of the Canada Elections Act, which requires federal elections to be held on the third Monday in October in the fourth calendar year after the polling day of the previous election, though a current government bill proposes to postpone the date to October 27, 2025 to avoid conflicting with Diwali. In addition to the statutory fixed election date provisions, Canada has a constitutional requirement specified in both section 50 of the Constitution Act, 1867 and section 4 of the Canadian Charter of Rights and Freedoms that elections for the House of Commons must be held no more than five years after the preceding election.

The election may occur before the scheduled date if the governor general dissolves Parliament on the recommendation of the prime minister for a snap election, for example after the House of Commons passes a motion of no confidence in the government. Early elections are more likely to occur during minority governments because the prime minister does not control a majority in the House of Commons.

Depending on the date the election is called, it may be the first contested using a new 343-constituency electoral map based on the 2021 Canadian census. New electoral boundaries for each of the ten provinces were finalized between February 14, 2023 and July 8, 2023, and officially proclaimed on September 22, 2023. Any election that is called on or after April 22, 2024, will use the new boundaries, while any called prior will re-use the 338-seat boundary set presently in force.
