Trump Signs Order Lowering Metals Tariffs
Canada's steel and aluminum sectors got a potential reprieve late Monday after U.S. President Donald Trump signed a proclamation amending his Section 232 national security tariffs on certain imports of steel, aluminum, and copper — dropping the rate from 25 per cent to 15 per cent.
The Section 232 tariffs, originally justified on national security grounds, have been a persistent thorn in Canada-U.S. trade relations since they were first introduced during Trump's first term. Canada is one of the largest suppliers of steel and aluminum to the American market, and Canadian producers have long argued the tariffs are unfair given the deeply integrated nature of the two countries' economies.
Why This Matters for Canadian Industry
The reduction from 25 to 15 per cent is meaningful, though industry groups will be quick to note it still represents a significant barrier. Canadian steel mills — concentrated in Ontario and Quebec — ship billions of dollars worth of product south of the border each year. Even a 10-percentage-point cut can translate into real savings for manufacturers and help restore some competitiveness.
Aluminum producers in Quebec, which hosts some of the largest smelting operations in North America, have similarly been squeezed by the tariff regime. The province's hydro-powered smelters produce aluminum at some of the lowest carbon intensities in the world — a selling point that has gained traction with American buyers looking to green their supply chains.
Copper, while a smaller piece of the puzzle, is critical for the clean energy transition — used heavily in electric vehicles, solar panels, and grid infrastructure. Canadian mining companies with copper operations stand to benefit from the easing as well.
The Bigger Trade Picture
The move comes amid ongoing uncertainty in the Canada-U.S. trade relationship. Ottawa has been pushing Washington for more predictable and stable trade terms, particularly as both countries navigate the CUSMA (Canada-U.S.-Mexico Agreement) framework. Canadian officials have repeatedly argued that tariffs on Canadian metals undermine North American supply chain resilience — especially at a time when both governments are trying to reduce reliance on Chinese metals.
Federal ministers in Ottawa are expected to respond cautiously, welcoming any reduction while continuing to press for full tariff elimination. Canadian industry associations had been lobbying for relief, citing job losses and investment uncertainty in steel towns like Hamilton and Sault Ste. Marie.
What Happens Next
It remains to be seen whether the proclamation applies broadly to Canadian exports or targets specific product categories. The details of which metals grades or import streams qualify for the lower rate will determine the real-world impact on Canadian producers.
Trade lawyers and industry groups will be combing through the fine print in the coming days. In the meantime, Canadian manufacturers — many of whom import U.S. steel for their own production — may also see some downstream relief in raw material costs.
For now, the announcement signals at least a partial thaw in the metals trade dispute, though Canada's position has always been clear: the tariffs should come down entirely.
