Advance voting in 3 Ontario byelections: What you need to know
Posted August 26, 2026 11:14 am.
Eligible voters in the ridings of Scarborough Southwest, York-Simcoe and Hamilton East-Stoney Creek can cast their ballots in advance polls ahead of the byelections on Sept. 3
A byelection became necessary in Scarborough Southwest after Doly Begum, who had held the riding for the NDP since 2018, vacated the seat in February. The Conservatives will look to keep the seats vacated in York-Simcoe by Caroline Mulroney and in Hamilton East-Stoney Creek, which had been represented by Neil Lumsden.
