Mark Carney is Canada’s next prime minister

OTTAWA — Mark Carney was sworn in as Canada’s 24th prime minister on Friday in the middle of a trade war and with an election battle on the way.

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.

Carney also introduced his new Cabinet built to go head-to-head with President Donald Trump’s administration, as Ottawa lawmakers navigate the fallout of the president’s protectionist policies that one way or another will reshape Canada’s economy.
