(Toronto, ON – April 27, 2026) — As business leaders from across the province gathered for the 2026 Ontario Chamber of Commerce (OCC) AGM and Convention under the theme “Ontario Connected: Business Without Barriers,” a clear message emerged: the recent expansion of U.S. Section 232 tariffs is putting jobs, investment, and integrated supply chains at risk in Ontario, and across the binational Great Lakes region.
The recent expansion of U.S. duties to the entire value of steel, aluminum, copper and derivative products – not just the metal content – poses an immediate risk to 15,000 jobs in southwestern Ontario alone, and thousands more in manufacturing supply chains across the province and in U.S. states.
“After a year in which tariffs devastated manufacturing in both Canada and the U.S., this new measure throws another wrench in the engine of the North American economy,” said Daniel Tisch, President and CEO of the Ontario Chamber of Commerce. “These tariffs are not well-understood, and that’s why Ontario businesses are sounding the alarm. Without swift relief, orders will vanish, investments will be shelved, and good jobs will be lost.”
