2024 Durham federal by-election

A by-election was held in the federal riding of Durham in Ontario on March 4, 2024, following the resignation of Conservative MP, and former Leader of the Conservative Party, Erin O'Toole.

Constituency
The federal riding of Durham covers most of the southeastern part of the Regional Municipality of Durham, on the eastern edge of the Greater Toronto Area. The district includes the entirety of the Township of Scugog and roughly half of the geographic area of the Municipality of Clarington, including the communities of Bowmanville and Courtice. The riding also includes the northern part of the City of Oshawa.

This is the third iteration of a riding under this name, with the current riding coming into use in 2004, when Clarington—Scugog—Uxbridge was renamed. Durham is considered a relatively safe seat for the Conservatives, who have held the seat since 2004.

Representation
The riding of Durham was vacated on August 1, 2023, following the March 31 announcement from Conservative MP Erin O'Toole that he would resign his seat, just over a year after he was removed as Leader of the Official Opposition and Conservative leader. O'Toole had held the seat since a 2012 by-election in which he was elected to replace Bev Oda. The by-election was called for March 4, 2024.
