After nearly a decade in power, Canadian Prime Minister Justin Trudeau finally bowed to a chorus of criticism that had become too loud to ignore, announcing his resignation on Monday. Among the loudest critics was one of his most loyal and longest-serving deputies.

Canada's governing Liberal Party will announce the country's next prime minister on March 9 after a leadership vote that follows the resignation of Justin Trudeau this week, party leaders said late Thursday.

The leadership change comes at a challenging time for Canada, with domestic and international pressures mounting.

Justin Trudeau announced his resignation as Canadian prime minister on Monday, ending his nine-year tenure amid cratering support from voters and his own Liberal Party. During a Monday speech, Trudeau said he plans to remain in office until the Liberal Party selects a new leader.
