Prime Minister Mark Carney says U.S. President Donald Trump respected Canada's sovereignty when the two leaders spoke on the phone Friday, marking a shift in the relationship — at least for now.

Canadian Prime Minister Mark Carney called for an April 28 snap election just nine days after taking office, citing Trump's trade actions as a threat to sovereignty.

The call on Friday comes as Trump has declared a trade war on Canada and has threatened to use economic coercion to make Canada the 51st U.S. state, a position that has infuriated Canadians.
