Canadian Prime Minister Justin Trudeau could announce his resignation within days, according to media reports.
He is considering stepping down as leader of the ruling Liberal Party, which would also end his nine years as prime minister.
Last month, its finance minister resigned, citing political differences such as how to handle Donald Trump's threat to impose US tariffs on Canadian goods.
Trudeau's popularity has also plummeted among voters, with polls suggesting his party is on course to lose this year's general election.
The This is reported by the Globe and Mail he may announce his intention to stand down before meeting his party's caucus on Wednesday to avoid the perception that his own MPs have ousted him.
Their sources said it was unclear whether Trudeau would leave immediately or stay on as prime minister until a new leader was chosen.
And they stressed that he has not yet made a final decision about his future.
Whoever takes over will have to lead the party through an election campaign while navigating a possible trade war with the US.
The election must be held before October, but a change in the leadership of the Liberal Party could increase calls for an early vote in the coming months.
Trudeau's departure will end a defining era in Canadian politics.
He unexpectedly swept his party into power in 2015, winning a campaign that began with them in third place.
The fresh-faced young leader, then 43, promised a new kind of politics centered on open immigration, tax increases for the wealthy and a fight against climate change.
But his first term was accompanied by scandals. In recent years, he has struggled with declining popularity as disenchantment grew with the cost of living and his own style of government.
More than a dozen of his own MPs have called on him to step down, while polls show two-thirds of voters disapprove.
Just 26 percent of those polled in September's Ipsos poll said Trudeau was their top choice for prime minister, putting him 19 points behind Conservative leader Pierre Poillievre.
History is not on Trudeau's side either, with only two prime ministers serving four consecutive terms.
Poilievre rose to the top of his party in 2022. with a promise to cut taxes, tackle inflation and protect personal liberties.
The 45-year-old also rallied support behind Freedom Convoy truckers protesting the Covid mandates, a blockade that has brought Canadian cities including Ottawa to a standstill.
Canada's next prime minister will have to deal with 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 protect its shared border against the flow of illegal migrants and illegal drugs.
The “serious challenge” this presents was outlined in the resignation letter of Finance Minister Chrystia Freeland, who quit hours before presenting her annual budget.
She said Trudeau informed her he no longer wanted her to be his government's chief economic adviser.
