James Garfield Gardiner, 64, called for increased immigration and closer ties to the United Kingdom. His support was strongest in Alberta, British Columbia, and his home province of Saskatchewan, and he was seen as St. Laurent's primary competition. His convention speech, which went over the allotted 20 minutes, asked for a chance to be the party's "spark plug." King campaigned hard against Gardiner, calling his campaign "ruthless and selfish," and criticized his tactics.[2]
Charles Gavan Power, 60, had resigned from cabinet during World War II amidst the Conscription Crisis of 1944 due to his opposition to conscription. Power left the Liberals to sit as an "Independent Liberal," and was elected as such during the 1945 election. Following the war, Power rejoined the Liberals. His convention speech called for electoral reform (including placing limits on campaign spending), and called on the party to return to its policy of protecting individual rights.[2]
Louis St. Laurent, 66, was King's personal choice, and King campaigned hard for St. Laurent to win. King lobbied hard behind the scenes, reversing his earlier pledge not to vote on the first ballot and convincing various other cabinet ministers (as seen below) to enter the race and withdraw in favour of St. Laurent. St. Laurent's support was seen as strong throughout the country, especially Ontario and Quebec. St. Laurent's convention speech told delegates that his government would fight to prevent the spread of communism abroad, and that the Liberals were the only party capable of bridging the gap between English Canada and French Canada, and respect provincial rights.[2]
