The Globe and Mail reports in its Wednesday edition that Prime Minister Mark Carney's second visit to the White House ended without relief from U.S. tariffs, but President Donald Trump predicted a future deal between Canada and the United States. The Globe's Steven Chase and Adrian Morrow write that Dominic LeBlanc, the minister responsible for Canada-U.S. trade, stayed in Washington to continue talks while Mr. Carney returned home. Mr. Trump expressed uncertainty about preserving the United States-Mexico-Canada Agreement but praised Canada for reducing fentanyl trafficking and suggested Canadians would ultimately be pleased with the negotiations. In remarks in the Oval Office, Mr. Trump indicated that the U.S. and Canada might return to managed trade in autos and steel, similar to arrangements before the 1980s free-trade era. The two leaders also discussed trade at the White House in May. Mr. Trump explained that the U.S. and Canada have a "natural conflict" over auto manufacturing and steel, as the U.S. wants to reduce imports of cars and steel from Canada. Mr. Trump mentioned that Washington and Ottawa are "working on formulas" for an auto deal, likely referring to a tariff-rate quota.
