The leaders of Canada and Mexico criticized U.S. President Donald Trump’s increase of steel and aluminum tariffs from 25% to 50%, which took effect on Wednesday. Canadian Prime Minister Mark Carney deemed the tariffs “unjustified” and “illegal,” while Mexican President Claudia Sheinbaum warned of significant impacts on Mexico’s industries and indicated potential countermeasures. Both countries, heavily reliant on trade with the U.S., are considering retaliatory actions to protect their manufacturing sectors amidst escalating trade tensions.
