The Globe and Mail reports in its Wednesday, Aug. 5, edition that trade negotiators are reviving a proposal to impose a quota system on Canadian steel and aluminum exports in exchange for lower United States tariffs on these metals as the deadline for new tariffs approaches. The Globe's Adrian Morrow and Mark Rendell report that Intergovernmental Affairs Minister Dominic LeBlanc and chief negotiator Janice Charette visited Washington for the second time in two weeks as pressure mounts to advance stalled trade talks. Their schedule this week includes meeting with U.S. industry groups that support the U.S.-Mexico-Canada Agreement, as well as sitting down with senators. It was unclear whether Mr. LeBlanc would meet with U.S. Trade Representative Jamieson Greer, Commerce Secretary Howard Lutnick or any other members of the Trump administration. One key to the discussions is a plan under which Canadian metals shipments to the U.S. would be limited in exchange for Mr. Trump reducing his 50-per-cent tariffs on them, similar to a proposal on the table last fall. Canada has made concessions to Mr. Trump, including scrapping a digital-services tax and reducing a content levy on streaming, but trade talks are still stalled.
