Today in Canada's Political History - June 21, 1957: John Diefenbaker becomes Prime Minister

  • National Newswatch

Canada’s Tories had a lot to be happy about on this date in 1957 with John Diefenbaker’s swearing-in as the nation’s 13th Prime Minister. This marked the first time Canada would have a Progressive Conservative PM and government since the days of R.B. Bennett in the 1930s. Dief and his team had defeated Louis St.-Laurent’s Liberals to take power and would remain in office until 1963.
