Municipal elections were held in Toronto, Ontario, Canada, on January 1, 1920. Mayor Tommy Church was elected to his sixth consecutive term in office. The most notable feature of the election was Constance Hamilton winning a seat in Ward 3. She became the first woman elected to as high a post in any government in Ontario.
Church had first been elected mayor in 1915 and had been reelected every year since. He was opposed by Controller Sam McBride and James M.H. Ballantyne who was Labour's candidate. Church was reelected, but not by an overwhelming margin.
Two new members of the Board of Control were elected. J. George Ramsden and Joseph Gibbons. One of the vacancies was created by McBride's decision to run for mayor. Sitting Controller William D. Robbins was the only incumbent defeated.
