Sam McBride was elected mayor in a three-way race in which incumbent James Simpson finished third.
He was the first Co-operative Commonwealth Federation (CCF) member and first socialist elected mayor of the city.
The CCF was still a minority in "Tory Toronto" and Simpson's anti-Catholic sentiments also hurt him with the electorate.
Former alderman Harry W. Hunt, who had also placed second to Simpson in 1935, finished second again although he had the endorsement of the three conservative newspapers: The Globe, The Mail, and the Telegram.
Controller William D. Robbins who had been serving as Acting Mayor due to McBride's ill health was unanimously appointed Mayor on November 18; the Board of Control vacancy was not filled.
