Canadian Prime Minister Justin Trudeau is facing the biggest test of his political career following the resignation of Finance Minister Chrystia Freeland, long one of his most powerful and loyal minis

Chrystia Freeland said she was quitting in the wake of a meeting last Friday with Trudeau, who asked her to take on a lesser post after the two had been arguing for weeks over spending.

Finance Minister Chrystia Freeland resigned from Prime Minister Justin Trudeau’s cabinet because of differences over how to prepare for the Trump administration, a political earthquake that shakes Canada’s government to its core.
