The details of the conversations between the two leaders, and subsequent discussions among top U.S. and Canadian officials, have not been previously fully reported, and were shared with The New York Times on condition of anonymity by four people with firsthand knowledge of their content. They did not want to be publicly identified discussing a sensitive topic.

On those calls, President Trump laid out a long list of grievances he had with the trade relationship between the two countries, including Canada’s protected dairy sector, the difficulty American banks face in doing business in Canada and Canadian consumption taxes that Mr. Trump deems unfair because they make American goods more expensive.

He also brought up something much more fundamental.

He told Mr. Trudeau that he did not believe that the treaty that demarcates the border between the two countries was valid and that he wants to revise the boundary. He offered no further explanation.
