Canadian ministers emerged from a lengthy, high-level meeting between Canada and the United States on Thursday without immediate relief from U.S. tariffs on Canadian imports, but they said the discussion was constructive and that talks would continue.

Canada's incoming Prime Minister Mark Carney said Wednesday he's ready to meet with U.S. President Donald Trump if he respects Canadian sovereignty and is open to talk about a common approach to trade.

U.S. President Donald Trump's choice for United States ambassador to Canada faced tough questions in his Senate nomination hearing Thursday, as the relationship between the two countries is strained by tariffs and threats of annexation.
