Mark Carney was sworn in as Canada’s prime minister on Friday — and depending on the outcome of the next election, he could be the country’s shortest-serving leader.

Mark Carney, the former governor of the Bank of Canada, was overwhelmingly elected the leader of the Liberal Party and the Great White North's next prime minister on Sunday.

To win the next election, the new prime minister must quickly prove he is Canada’s best hope of managing relations with the White House.
