Former central banker Mark Carney will be sworn in as Canada's next prime minister on Friday with the country rattled by a breakdown in relations with the United States. But he steps into office as US President Donald Trump imposes sweeping import tariffs and repeatedly taunts to annex the country as the 51st state of the United States.

Mark Carney will be sworn in as prime minister today along with a new look cabinet that will simultaneously try to move on from the previous Liberal government while maintaining stability during an ongoing trade war with the United States.
