The 1968 Canadian Federal Election, a contest between Newly Minted Liberal Party Prima Minister Pierre Eliot Trudeau, and Progressive Conservative Party Leader Robert Stanfield turned in a landslide for Trudeau, allowing him to turn the minority government he inherited from Lester Pearson into a Majority Government
Following a battle over a tax bill that escalated into a confidence motion where the government barely survived—thanks to both the NDP's and Ralliement Créditiste's unwillingness to force an early election and hand Conservative leader Robert Stanfield an election victory a it was clear that Liberal PM Lester Pearson coult not continue to serve as Prime minister; forcing him to call a Liberal leadership election and leave the prime ministership.
Here, a multitude of established Liberal Politicians, such as Paul Martin Sr, Ran to try and replace Pearson, but the one who would get the job—in a surprise upset—was the relative unknown justice minister Pierre Elliot Trudeau.
Young, Single, Charismatic, uncontrovercial (at the time) and most importantly: French Canadian, This victory signalled the beggining of Trudeaumania—a canadian social phenomenon that would carry the Liberals to a landslide win.
Here, the Liberal campaign was bereft of policy specifics, but heavy on emotions; working by means of popular sentiment to attempt to unify Canada at a time of Growing Francophone and Anglophone divisions in Canada.
With Trudeau taking advantage of this division to singal that electing him, personally, would help to Unify the country as he'd work toward that aim—heavilly focusing on the notion of One Canada (That Canada is one Nation with two countries within it), taking advantage of conservative missteps on the issue to portray them as anti-Canadian, and himself as pro-canadian (enphasicint Bilingualism in the proccess).
Calling the election the moment he got into power Trudeau explained away the move by 'getting rid of the uncertainty of a minority government' to which Stanfield attacked by claiming that he was depriving canadians on their ability to judge his governing experience.
However, throughout the campaign Stanfield refused to hit Trudeau hard, a soft-hitting manner that had served him well in his own leadeship contest that was now itself harming the conservative leader, giving him less of a personality than the novel Trudeau
This personality, catalogued as the first Canadian Presidential election, redefined politics as it tied the election closely to Trudeau's very being and personal popularity—drawing crowds of 60,000 to Stanfield's 3,000
In the end, All of this resulted in Trudeau winning a Full Term, Losing only the Maritimes where Stanfield was personally popular (He was the Nova Scotia Premiere for 12 years), before trouncing them in the rest of Canada—even winning seats in the Tory's Prairy Heartlands.
In doing so, handing Trudeau a lopsided nigh uniparty parliament; one which granted him a bold mandate to affect Canada with little opposition until the next election.
