The 1968 Canadian federal election was held on June 25, 1968, to elect members of the House of Commons of Canada of the 28th Parliament of Canada.
In April 1968, Prime Minister Lester Pearson of the Liberal Party resigned as party leader as a result of declining health and failing to win a majority government in two attempts. He was succeeded by his Minister of Justice and Attorney General Pierre Trudeau, who called an election immediately after becoming prime minister. Trudeau's charisma appealed to Canadian voters; his popularity became known as "Trudeaumania" and helped him win a comfortable majority. Robert Stanfield's Progressive Conservatives lost seats whereas the New Democratic Party's support stayed the same.

Background
Prime Minister Lester B. Pearson had announced in December 1967 that he would retire early in the following year, calling a new leadership election for the following April to decide on a successor. In February 1968, however, Pearson's government nearly fell before the leadership election could even take place, when it was unexpectedly defeated on a tax bill. Convention dictated that Pearson would have been forced to resign and call an election had the government been defeated on a full budget bill, but after taking legal advice, Governor General Roland Michener decreed that he would only ask for Pearson's resignation if an explicit motion of no confidence were called in his government. Ultimately, the New Democratic Party and Ralliement créditiste were not willing to topple the government over the issue, and even had they done so, Pearson would have been entitled to advise Michener not to hold an election until after the new Liberal leader had been chosen, but the incident made it clear that Pearson's successor could not feasibly hope to hold out until the next statutory general election date of November 1970, and would in all likelihood be forced to call an election much sooner.

Pierre Trudeau, who was a relative unknown until he was appointed to the cabinet by Pearson, won a surprise victory over Paul Martin Sr., Paul Hellyer and Robert Winters in the party's leadership election on April 6. He was sworn in as prime minister on April 20.

Parties and campaigns
Liberals
As had been widely expected, Trudeau called an immediate election after he was sworn in as prime minister. The charismatic, intellectual, handsome, single, and fully bilingual Trudeau soon captured the hearts and minds of the nation, and the period leading up to the election saw such intense feelings for him that it was dubbed "Trudeaumania." At public appearances, he was confronted by screaming girls, something never before seen in Canadian politics. The Liberal campaign was dominated by Trudeau's personality. Liberal campaign ads featured pictures of Trudeau inviting Canadians to "Come work with me", and encouraged them to "Vote for New Leadership for All of Canada". The substance of the campaign was based upon the creation of a "just society", with a proposed expansion of social programs.
Progressive Conservatives
The principal opposition to the Liberals was the Progressive Conservative Party (PC Party) led by Robert Stanfield, who had previously served as premier of Nova Scotia. The PCs started the election campaign with an internal poll showing them trailing the Liberals by 22 points.
Stanfield proposed introducing guaranteed annual income, though failed to explain the number of citizens that would be covered, the minimum income level, and the cost to implement it. Due to concerns that the term "guaranteed annual income" sounded socialist, he eventually switched to using the term "negative income tax". These mistakes made the policy impossible for voters to understand and harmed the PCs. What also damaged the PCs was the idea of deux nations (meaning that Canada was one country housing two nations - French Canadians and English-speaking Canadians). Marcel Faribault, the PCs' Quebec lieutenant and MP candidate, was unclear on whether he supported or opposed deux nations and Stanfield did not drop him as a candidate. This led to the Liberals positioning themselves as the party that supported one Canada. In mid-June, they ran a full-page newspaper advertisement that implied that Stanfield supported deux nations; Stanfield called the ad "a deliberate lie" and insisted he supported one Canada.
