Calls for Trudeau to step aside have grown since December amid a series of polls showing his Liberal Party being trounced in the next election due to voter anger over high prices and a housing crisis, Reuters reported.
Trudeau has also faced a series of mounting crises, including the abrupt resignation of Canada's finance minister Chrystia Freeland and Trump's threat of imposing crippling tariffs when he takes office.
The Canadian Broadcasting Corp said more than 50 Liberal members of parliament from Ontario − the most populous of the 10 provinces and the party's main stronghold − held a call Dec. 21 and agreed Trudeau had to step down.
