Municipal elections were held in Toronto, Ontario, Canada, on December 5, 1955. Incumbent mayor Nathan Phillips, elected a year earlier, was easily reelected, defeating Controller Roy E. Belyea and Trotskyist Ross Dowson. Two referendums were held with the elections. One, which passed, was to extend the municipal term to two years. Previously elections had been held every year. There was also a vote on funding a new Toronto City Hall, which was rejected by voters.
