New Canadian Prime Minister Mark Carney is heading to Paris and London on Monday to seek alliances as he deals with U.S. President Donald Trump's attacks on Canada's sovereignty and economy. Carney is purposely making his first foreign trip to the capital cities of the two countries that shaped Canada's early existence.

Ex-central banker Mark Carney was sworn in as prime minister of Canada on Friday and immediately said he could work with U.S. President Donald Trump, who is promising tariffs that could devastate the Canadian economy.

President Donald Trump since his second White House term began has said Canada, Greenland and the Panama Canal should become U.S. property.
