New Canadian Prime Minister Mark Carney is heading to Paris and London on Monday to seek alliances as he deals with US President Donald Trump’s attacks on Canada’s sovereignty and economy.

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

A spokesman for Canada's Defense Minister Bill Blair says new Prime Minister Mark Carney has asked for a review of the purchase of America's F-35 fighter jet.

Canada’s new Prime Minister Mark Carney ordered a review of the country’s contract with the US’s Lockheed Martin Corp for F-35 fighter jets, a new front in the dispute between the two sides in response to tariffs and expansionist rhetoric from President Donald Trump.

Canada is reexamining its purchase of U.S.-built F-35 stealth fighter jets amid growing rancor over the Trump administration's tariffs on its northern neighbor and threats by President Donald Trump that it will become the 51st state.
