Municipal elections were held in Toronto, Ontario, Canada, on December 3, 1951. Allan Lamport defeated incumbent Hiram E. McCallum in the mayoral election.
Lamport had challenged McCallum the previous year but had lost by a narrow margin. McCallum had originally planned on retiring and being succeeded by Controller John Innes, but Innes died unexpectedly during the year. The 1951 also saw an attempt at the mayoralty by alderman Nathan Phillips, who finished a distant third. In Phillips' autobiography he states that he expected fellow Conservative McCallum to retire, but that their both running split to vote and allowed Lamport to become the first Liberal elected to run the city since 1909.[1] Lamport ran under the slogan "Toronto needs a fighting mayor."
The only new arrival on the Board of Control was Ford Brand, secretary of the Toronto and District Labour Council. John Innes had died in office and his replacement Alfred Cowling decided to contest the 1951 Provincial Election. Former Controller and avowed Communist Stewart Smith made another attempt to return to the board, but finished a distant fifth.
