Ontario's mayoral races were decided Monday night, with the results a mix of upsets, tight races and easy incumbent victories.

In Toronto, David Miller easily won re-election, earning over 63 per cent of the vote to defeat Jane Pitfield.

Bob Chiarelli wasn't as fortunate in Ottawa, finishing third in an attempt to win a third mayoral term. Technology executive Larry O'Brien is the city's new mayor.

Under new provincial legislation, for the first time, all of the candidates elected on Monday will serve four-year terms instead of three.

Following are the mayoral results in some of the province's other cities:

  • Challenger Dave Aspden became the new mayor of Barrie, defeating Rob Hamilton.
  • Longtime provincial Tory MPP Cam Jackson emerged from a competitive race in Burlington in the bid to succeed Rob MacIsaac.
  • In Hamilton, Fred Eisenberger won a seesaw battle over incumbent Larry Di Ianni.
  • Kingston mayor Harvey Rosen won a tight race over challenger Rick Downes, winning by less than 800 votes. Rosen won 83.5 per cent of the vote in the last election.
  • Carl Zehr won two-thirds of the vote in Kitchener, securing another term.
  • Anne Marie DeCicco-Best won a third term in London, turning aside the mayoral bid of Joe Fontana, who had represented the city for the last 16 years federally as a Liberal MP.
