The last polling stations closed at 04 Swedish time and in the early counting of votes, the Liberals have 131 seats in parliament, significantly more than the main challenger, the Conservative Party, which stands at 73 seats.
It takes 170 to form a majority government.
According to CTV, it is clear that the Liberals, led by Trudeau, will be able to form a government, but it is still unclear whether it will be a majority government, or a minority government as it is today.
Announced new elections in August
With two years left in office, Trudeau announced new elections in August - when he led a large part of public opinion - under the pretext that Canadians should have a say in who they want to be responsible for the costs of dealing with the pandemic.
"We can work to do great things during a pandemic, but we need a clear mandate to understand what Canadians want in the coming years," Trudeau said of his decision to call new elections.
He was not always self-evident
Trudeau's challenger for the post of Prime Minister has been Erin O'Toole, who in opinion polls ahead of the election appeared to have caught up with Trudeau in popularity.
During the election campaign, support for Trudeau seemed to decline and political opponents have criticized the decision to hold elections.
