The Financial Post reports in its Wednesday edition that the first order of business for Canada's new Liberal government under Mark Carney will be working out a deal with U.S. President Donald Trump on trade. The Post's Jordan Gowling writes that Mr. Trump has already slapped tariffs on Canadian steel and aluminum, as well as the auto sector. While other exports in compliance with the Canada-United States-Mexico Agreement (CUSMA) are currently exempted, it is not clear how long that will last. Complicating matters, Mr. Trump has revived his "51st state" threats and the U.S. has made it clear that it expects allies to pick up more of the tab for defence, meaning trade and security talks are likely to be intertwined. Mr. Trump will be looking for concessions including in Canadian auto manufacturing, Canada's supply management system and the digital sales tax. However, Canada remains a critical source of goods such as energy, critical minerals, potash and auto parts that the U.S. cannot live without, despite the President's claims. The Prime Minister will have to drive a hard bargain, while also attempting to save the remnants of the U.S.-Canada trade relationship.
