U.S. President Donald Trump, who has imposed tariffs on Canadian goods and threatened to make Canada the 51st state, has loomed large over the contest.

Carney, 59, will succeed Justin Trudeau, who announced in January that he would step down amid low approval ratings following a decade in office.

Mark J. Carney ’87 defeated fellow Harvard College alum Chrystia A. Freeland ’90 and two other Liberal Party candidates to become the 24th Prime Minister of Canada and the new leader of the Canadian Liberal Party on Sunday afternoon.
