2023 Winnipeg South Centre federal by-election

A by-election was held in the federal riding of Winnipeg South Centre in Manitoba on June 19, 2023, following the death of Liberal MP and former cabinet minister Jim Carr.

The by-election was held on the same day as three others; Notre-Dame-de-Grâce—Westmount, Oxford and Portage—Lisgar.

Constituency
The district is an urban constituency based in the city of Winnipeg.

Representation
Winnipeg South Centre has been a reliable Liberal seat since 1988, apart from 2011 to 2015 when it was held by Conservative Joyce Bateman.

The riding of Winnipeg South Centre was vacated on December 12, 2022 following the death of Liberal MP and former cabinet minister Jim Carr. Carr had represented the riding since 2015, when he defeated Conservative incumbent Joyce Bateman, and had been battling multiple myeloma and kidney failure since 2019. Carr also defeated Bateman in rematches in 2019 and 2021.

Candidates
Jim Carr's son Ben Carr, an educator and former staffer to Mélanie Joly, won the Liberal nomination for the by-election. Winnipeg city councillor Sherri Rollins briefly ran for the nomination before withdrawing and throwing her support behind Carr.

The Conservatives nominated Damir Stipanovic, an air traffic controller and member of the Royal Canadian Air Force Reserve.

After previously running in the same riding in the 2021 federal election, NDP candidate Julia Riddell, a clinical psychologist, and Green candidate Doug Hemmerling, a local educator, won their respective parties' nominations for the by-election.

The People's Party of Canada chose former DJ Tylor Baer to be their candidate. He contested Brandon—Souris for the party in 2021.

The Rhinoceros Party chose party leader Sébastien CoRhino to be their candidate.

The Longest Ballot Committee chose Winnipeg South Centre as its target for this group of by-elections; the group protests first-past-the-post voting by registering large numbers of independent candidates in one riding in an election or group of by-elections. Forty-two people, including the above-mentioned Sébastien CoRhino, ran under its auspices, while Tait Palsson, who was not involved with the group, also ran an independent campaign. The forty-eight candidates in this by-election are the most ever to contest a federal election in Canada.
