A source says embattled Canadian Prime Minister Justin Trudeau is not expected to announce a decision on his future over the Christmas holidays.

In 2017, Mr. Trudeau came under pressure to stand up to Donald J. Trump, the newly elected U.S. president. As Mr. Trump restricted immigration, Mr. Trudeau restated Canada’s openness to asylum seekers, proclaiming, “ Diversity is our strength .”

Canada appears to be barrelling toward a spring election now that the NDP is vowing to vote down the government early next year — whether Trudeau stays on or not.
