Municipal elections were held in Toronto, Ontario, Canada, on December 3, 1962. Incumbent mayor Nathan Phillips, then the longest-serving mayor in Toronto history, lost to Controller Donald Summerville by a significant margin. Two major referendums were also held in Metro Toronto. The most controversial was over water fluoridation, which passed by a slim margin of 166,960 to 163,240. The areas outside Toronto also voted to remove some of the last of the Blue Laws by allowing movies to be shown on Sundays, something that was already allowed in the city itself.
