Ontario municipal elections, 1997

The 1997 Ontario municipal elections were led in all municipalities across the Canadian province of Ontario on November 10, 1997, to elect mayors and reeves, councillors, and school trustees. There were also referendum questions in some municipalities.

The most closely watched contest was in the newly amalgamated city of Toronto, where Mel Lastman narrowly defeated Barbara Hall to win the mayoralty. In other results, Hazel McCallion was re-elected in Mississauga, Bob Morrow was returned in Hamilton, and Dianne Haskett was elected in London.
