1945 Canadian federal election

A key issue in this election seems to have been electing a stable government. The Liberals urged voters to "Return the Mackenzie King Government", and argued that only the Liberal Party had a "preponderance of members in all nine provinces". Mackenzie King threatened to call a new election if he was not given a majority: "We would have confusion to deal with at a time when the world will be in a very disturbed situation. The war in Europe is over, but unrest in the east is not over."

Social welfare programs were also an issue in the campaign. Another Liberal slogan encouraged voters to "Build a New Social Order" by endorsing the Liberal platform, which included

• $750 million to provide land, jobs and business support for veterans;
• $400 million of public spending to build housing;
• $250 million for family allowances;
• establishing an Industrial development Bank;
• loans to farmers, floor prices for agricultural products;
• tax reductions.

The Progressive Conservatives tried to capitalize on the massive mid-campaign victory by the Ontario Progressive Conservative Party in the 1945 Ontario provincial election. PC campaign ads exhorted voters to rally behind their party: "Ontario shows! Only Bracken can win!", and suggesting that it would be impossible to form a majority government in the country without a plurality of seats in Ontario, which only the Tories could win.

Operation Downfall, the invasion of Japan, was scheduled for late 1945-early 1946. Bracken had promised conscription for the invasion of Japan whereas King had promised to commit one division of volunteers to the planned invasion of Japan.[5] Based on the way that the Japanese had fought the battles of Iwo Jima and Okinawa it was widely expected that the invasion of the Japanese home islands would be a bloody campaign, and Bracken's promise of conscription for the planned invasion of Japan did much to turn voters against his party.[6]

Despite the party's performance ultimately being their best since R.B. Bennett's government was ousted in a landslide a decade previously, Bracken was widely held responsible for their failure to make a better showing – aside from the conscription issue, many believed that his western populism was a futile approach, and that the Tories could not hope to compete with the CCF and Socreds in the west – and the party grandees immediately began pressuring him to resign in favour of George A. Drew, who had led the Ontario Progressive Conservatives to their provincial election victory; Bracken would eventually do so in 1948.

Campaigning under the slogan, "Work, Security, and Freedom for All – with the CCF", the CCF promised to retain war-time taxes on high incomes and excess profits in order to fund social services, and to abolish the Senate of Canada. The CCF fought hard to prevent the support of labour from going to the Labor-Progressive Party (i.e., the Communist Party of Canada).

The LPP, for its part, pointed out that the CCF's refusal to enter into an electoral pact with the LPP had cost the CCF 100,000 votes in the Ontario election, and had given victory to the Ontario PCs. It urged voters to "Make Labour a Partner in Government."

The Social Credit Party of Canada tried, with modest success, to capitalize on the positive image of the Alberta Socred government of William Aberhart, asking voters, "Good Government in Alberta -- Why Not at Ottawa?". Referring to social credit monetary theories, the party encouraged voters to "Vote for the National Dividend".
