Canada will impose retaliatory tariffs on C$27.6 billion (approximately US$19.94 billion, or roughly ¥3.2 trillion) of U.S. products starting September 8, after the United States introduced new duties on Canadian goods. The measures cover about 700 product categories, with rates of 15%, 25% and 50%. Steel, aluminum, furniture and apparel will face the highest rate, while cheese, home appliances and certain seafood products will be subject to 25% duties, and electronics and tools to 15%. Canadian officials said the package was designed to match the approximate scale of U.S. tariffs while pressuring the U.S. economy and limiting harm to Canadian consumers and businesses. Ottawa also announced fiscal support for domestic companies and workers affected by the intensifying trade war. The United States activated additional 50% tariffs on about US$20 billion of Canadian products on the 22nd after trade negotiations broke down. The dispute threatens higher inflation, rising North American production costs and further pressure on automotive supply chains.
