The 1972 Canadian federal election was held on October 30, 1972, to elect members of the House of Commons of Canada of the 29th Parliament of Canada. It resulted in a slim victory for the governing Liberal Party, which won 109 seats, compared to 107 seats for the opposition Progressive Conservatives. A further 48 seats were won by other parties and independents. On election night, the results appeared to give 109 seats to the Tories, but once the counting had finished the next day, the final results gave the Liberals a minority government and left the New Democratic Party led by David Lewis holding the balance of power.
