The 30th Canadian Parliament was in session from September 30, 1974, until March 26, 1979. The membership was set by the 1974 election on July 8, 1974, and was only changed somewhat due to resignations and by-elections before it was dissolved prior to the 1979 election.
It was controlled by a Liberal Party majority led by Prime Minister Pierre Trudeau and the 20th Canadian Ministry. The Official Opposition was the Progressive Conservative Party, led first by Robert Stanfield, and then by Joe Clark.
The sessions were prorogued (reason unknown currently).
The Speaker was James Jerome. See also the List of Canadian electoral districts 1966-1976 for a list of the ridings in this parliament.
