Trudeau, speaking to reporters in Brussels, also reiterated that Canada would respond with countermeasures if need be. U.S. President Donald Trump is threatening tariffs on steel and aluminum as well as a broader tariff on all Canadian imports.

Trump set a 25% tariff, essentially a tax, on any steel and aluminum coming into the United States. As a result, consumers could expect to pay more for a wide range of products, from appliances and automobiles to canned beverages and sporting goods.

President Trump announced new tariffs on steel imports, part of a plan he said will boost manufacturing in the United States. The tariffs go into effect next month.

"The change in the current trade scheme for aluminium and steel would be detrimental to the productive fabric in aggregate terms," the lobby said in its note, adding that Spain's total cast iron and steel exports to the U.S. reached 944 million euros ($977 million) in 2023.
