'Canada is not for sale…': Mark Carney tells Trump; US President says 'never say never'

U.S. President Donald Trump began his first talks with Canadian Prime Minister Mark Carney on Tuesday and vowed to bring up "tough points" that are dividing the two countries since Trump imposed tariffs. Their meeting started with smiles and a handshake despite Trump's desire to make Canada the 51st U.S. state, a prospect that has chilled bilateral relations. The subject quickly came up as they took questions from reporters."We're not going to be discussing that unless somebody wants to discuss it," Trump said. "It would really be a wonderful marriage."
