The United States and Canada moved closer to a provisional trade agreement that would avert threatened 50% U.S. tariffs on about $20 billion of Canadian imports, while earlier reporting indicated the broader deal could include cutting the tariff on Canadian imported cars to 15% from 25%. President Donald Trump said the emerging agreement was "very fair" and would benefit U.S. farmers and manufacturers, while a senior Canadian official called it "a very good deal for Canada" but cautioned negotiations were not complete. The tariff deadline was pushed back to 12:01 a.m. Saturday. The senior Canadian official said the emerging terms would provide greater certainty, protect jobs threatened by the tariffs and preserve Canada's favorable access to the U.S. market. Canada also said its dairy supply management system was "not on the table," even as Trump claimed tariffs on U.S. agricultural products entering Canada would be reduced to zero, leaving unresolved how additional market access for U.S. farmers would be achieved. Another sticking point is alcohol: the White House says Canada has committed to address provincial restrictions on U.S. alcohol, but Prime Minister Mark Carney cannot directly force provinces to reverse those measures. The dispute stems from Trump's use of Section 338 of the Tariff Act of 1930 to threaten 50% duties on a slice of Canadian exports equal to roughly 5% of the country's shipments to the United States, citing discrimination against U.S. autos, alcohol and cheese and anger over Canada's retaliatory tariffs. The immediate dispute is also being watched as a possible bridge to broader negotiations over the U.S.-Mexico-Canada Agreement, as both governments try to avoid a deeper trade escalation that could disrupt integrated North American supply chains.
