Municipal elections were held in Toronto, Ontario, Canada, on December 6, 1937. Ralph Day was elected mayor defeating incumbent William D. Robbins.
Toronto mayor
William D. Robbins had been appointed to the office of mayor a year and half previously. He was opposed by the much younger Controller Ralph Day. Day won by a significant margin, beating Robbins in all but two wards. Also running were fringe candidates Carlo Lamberti, a music teacher, and veteran Robert Harding.
There was one opening on the Board of Control after Day chose to run for mayor. The race turned out to be a close contest between Alderman Douglas McNish and prominent communist Tim Buck with McNish winning by a few hundred votes. Further back was Alderman Robert Hood Saunders.
