Ontario mayor election results 2026: who won in every big city

Mayors in Mississauga, Kingston, Windsor, Oakville, Milton, Waterloo and Niagara Falls lost on Monday, and Hamilton's Andrea Horwath finished third. In 2022, every mayor in these cities who ran again won.

Twenty sitting mayors in Ontario's larger cities ran again on Monday. Eight lost, including Andrea Horwath, who finished third in Hamilton. A ninth, Martin Ritsma in Stratford, is running third with votes still being counted.

Four years ago the same cities sent a very different signal. Of the 11 mayors who ran for re-election in 2022, all 11 won. The other nine seats were open.

The mayors who lost

Most of the defeated mayors didn't just slip. They lost 20 to 30 points of support from their last win.

Bryan Paterson won Kingston with 74% in 2022. This time he got 41% and lost to Conny Glenn by 793 votes. Rob Burton, Oakville's mayor, finished third behind Jeff Knoll and Sean O'Meara. Gord Krantz in Milton fell from 50% to 25%, losing to George Minakakis.

In Windsor, Fred Francis beat Drew Dilkens 48% to 34%. Shannon Weber, who lost to Dorothy McCabe in Waterloo by about 300 votes in 2022, won the rematch 52% to 30%. Lori Lococo beat Jim Diodati in Niagara Falls.

Mississauga's Carolyn Parrish, elected in a 2024 by-election, lost to Alvin Tedjo, the runner-up in that by-election. Bonnie Crombie, the city's former mayor and the betting favourite on election morning, finished third.

Hamilton was the biggest surprise. Keanin Loomis, who lost to Horwath by about 1,700 votes in 2022, beat Rob Cooper 42% to 32%. Horwath, a former leader of the Ontario NDP, got 15%.

The mayors who held on

The mayors who were safe were very safe. David West in Richmond Hill (84%) and Frank Scarpitti in Markham (72%) both grew their share. So did Olivia Chow in Toronto, from 37% in a crowded 2023 by-election to 54% against Brad Bradford, a result the polls badly missed (how far off they were).

Others won with less room than before. Berry Vrbanovic in Kitchener dropped from 80% to 55%, and Josh Morgan in London from 66% to 45%. Mark Sutcliffe held Ottawa with 45%, down from 51%.

*Still counting. Toronto and Ottawa are called with a few polls left. Cambridge, Burlington, Greater Sudbury and Vaughan are not included because their results pages could not be read.

Four years ago, Ontario's big-city mayors looked close to unbeatable. On Monday, nearly half of them were out or on their way.
