It was controlled by a Liberal Party majority under Prime Minister Louis St. Laurent and the 17th Canadian Ministry. The Official Opposition was the Progressive Conservative Party, led by George Drew.
The Speaker was William Ross Macdonald. See also List of Canadian electoral districts 1947-1952 for a list of the ridings in this parliament.
