WEST PALM BEACH, Fla. (AP) — Canadian Prime Minister Justin Trudeau is returning home after his meeting with Donald Trump without assurances the president-elect will back away from threatened tariffs on all products from the major American trading partner. Trump says the dinner talks Friday night at his Mar-a-Lago club in Florida were “productive.” But he signaling no retreat from a pledge that Canada says unfairly lumps it in with Mexico over the flow of drugs and migrants into the United States. Trudeau spoke of “an excellent conversation” but offered no details. Trump said in a Truth Social post later Saturday that they discussed “many important topics that will require both Countries to work together to address.”
