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.

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 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.
