The 23rd Canadian Parliament was in session from October 14, 1957, until February 1, 1958. The membership was set by the 1957 federal election on June 10, 1957, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1958 election.
It was the first parliament opened by the Monarch of Canada, and the only parliament formally opened by Queen Elizabeth II herself, rather than her formal representative, the governor general. In 2025, King Charles III opened the 45th Canadian Parliament, marking the second time any monarch has opened parliament.
It was controlled by a Progressive Conservative Party minority under Prime Minister John Diefenbaker and the 18th Canadian Ministry. The Official Opposition was the Liberal Party, led first by Louis St. Laurent, and then by Lester B. Pearson.
It was the second shortest parliament in Canadian history.
The Speaker was Roland Michener. See also List of Canadian electoral districts 1952–1966 for a list of the ridings in this parliament.
There was only one session of the 23rd Parliament.
