Susan Lahey of the Progressive Conservative Party was declared the winner of the Ontario provincial byelection held on September 4, 2026 in the York‑Simcoe riding. The vote filled a vacant seat in the provincial legislature, bringing the riding back under representation after the vacancy arose.
The contest featured three main candidates. Lahey faced Naomi Davison, who ran for the Liberal Party, and Bobby Nikmard, representing the New Democratic Party. Voters in York‑Simcoe cast their ballots to choose among these three party nominees, each seeking to serve the constituency in the Ontario legislature.
Election officials reported that the turnout reflected the typical engagement levels for a byelection in the region, and the results were announced shortly after the polls closed. Lahey’s victory adds another Progressive Conservative member to the provincial assembly, while the Liberal and New Democratic candidates finished second and third respectively.
The byelection was called to address the vacancy that had left York‑Simcoe without a representative in the legislature. By filling the seat, the riding regains a voice in provincial debates and legislative decisions. The Progressive Conservative win maintains the party’s presence in the area, aligning with its broader representation across the province.
Local observers noted that the election outcome will shape the upcoming legislative session, as the new member joins colleagues from all three major parties. The result also sets the stage for future contests in York‑Simcoe as parties prepare for the next general election cycle.
The Ontario election authority confirmed that all procedural requirements were met and that the newly elected member will be sworn in during the next legislative sitting, officially commencing duties as the riding’s representative.
