Former finance minister Chrystia Freeland is billing herself as the best person to lead Canada's fight against Donald Trump.

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.

Chrystia Freeland has called for economic retaliation if President-elect Trump follows through with his threat to impose tariffs.
