In the federal byelections on Monday, two federal leaders have a lot on the line

The upcoming Monday byelections hold significant weight ahead of the next federal election, potentially boosting or damaging one or more political parties.

In the Elmwood–Transcona riding in Winnipeg, a tight race is expected between the NDP and Conservatives. Historically, the NDP has dominated the seat, having won 10 of the 11 elections since 1988.

However, if the Conservatives claim victory, it will strengthen their current lead and raise concerns over the NDP’s electoral strategy, especially after former MP Daniel Blaikie stepped down to join the provincial NDP government.

The NDP’s candidate is Leila Dance, while Colin Reynolds runs for the Conservatives, and Ian MacIntyre represents the Liberals.

In Montreal’s LaSalle-Émard-Verdun riding, the contest is more fragmented, with the Liberals, NDP, and Bloc Quebecois vying for the seat.

If the Liberals retain this traditionally Liberal seat, it would provide relief to Prime Minister Justin Trudeau following his party's loss in Toronto-St. Paul’s earlier this year. However, a loss would likely fuel leadership questions for Trudeau.

Laura Palestini is the Liberal candidate, with Craig Sauvé running for the NDP, Louis Ialenti for the Conservatives, and Louis-Philippe Sauvé for the Bloc Quebecois.

Montreal’s byelection is further complicated by an unprecedented 91 candidates on the ballot, many protesting the government’s inaction on electoral reform.

Election Canada is implementing measures to prevent a repeat of the lengthy vote count seen in Toronto’s June byelection.
