Trudeau’s popularity has also plummeted among voters, with polls suggesting his party is on course for a general election defeat this year.

The Globe and Mail reports that, external he could announce his intention to quit before his party’s national caucus meets on Wednesday, to avoid the perception that his own MPs forced him out.

Their sources said it was unclear whether Trudeau would leave immediately or stay on as prime minister until a new leader was selected.

And they stressed he had yet to make a final decision on his future.

Whoever takes over will have to lead the party through an election campaign while also navigating a possible trade war with the US.

The election must take place before October, but a change in leadership of the Liberal Party could increase calls for a snap vote in the coming months.

Trudeau’s departure would bring to an end a defining era in Canadian politics.

He unexpectedly swept his party to power in 2015, winning a campaign that began with them in third place.

The fresh-faced young leader, aged 43 back then, promised a new kind of politics centred on an open immigration policy, increased taxes on the wealthy and battling climate change.

But his first term was dogged by scandals. In more recent years, he had been battling sinking popularity as frustration grew with the cost of living and his own style of governing.

Dozens of Liberal MPs in Quebec, Ontario and Atlantic Canadian provinces have called for him to step down, while polls suggest two-thirds of voters disapprove of him.

Just 26% of respondents in a September Ipsos survey said Trudeau was their top pick for prime minister, putting him 19 points behind Conservative leader Pierre Poilievre.

History is also not on Trudeau’s side, with only two prime ministers ever serving four consecutive terms.

Poilievre rose to the top of his party in 2022 on a promise to reduce taxes, tackle inflation and protect individual liberties.

The 45-year-old also rallied support behind the Freedom Convoy truckers protesting about Covid mandates – a blockade that brought Canadian cities including Ottawa to a standstill.

Canada’s next prime minister will have to address the threat of tariffs from incoming US President Donald Trump.

He has vowed to impose a 25% tariff on Canadian goods if the country does not secure its shared border to the flow of irregular migrants and illegal drugs.

The “grave challenge” this posed was referred to in the resignation letter of Finance Minister Chrystia Freeland, who quit hours before she was due to deliver her annual budget.

She said Trudeau had informed her he no longer wanted her to be his government’s top economic adviser.
