Evolution of voting intentions in the Canadian federal election 2021

Two years ahead of schedule, federal elections were held on September 20, 2021 in Canada. Justin Trudeau's Liberal Party had lost its absolute majority in the 2019 elections, and on August 15, 2021, the Prime Minister, who was then in a strong position in the polls, asked the Governor General to dissolve Parliament.

The day after the dissolution was announced, the Liberal Party was leading the Conservative Party by five points in the polls. However, while Canadians' voting intentions changed only slightly, the gap between the two dominant parties narrowed, and on September 17, three days before the election, the parties of Justin Trudeau and Erin O'Toole won 32 and 33 percent of voting intentions respectively, with the Conservatives overtaking the Liberals by one point.
