The 1972 Toronto municipal election was held December 4, 1972, to elect the governments of Toronto, Ontario, Canada, the five other boroughs, and the government of Metro Toronto as well. The election was overshadowed by the 1972 federal election held October 30 and the American elections held November 7, but it resulted in a dramatic change in the city government. Four new mayors were elected, and 17 of 32 Metro seats were held by newcomers. In the City of Toronto, control of city council was won by the reform faction and reform leader David Crombie was elected mayor.
