The European Union is broadening the list of US goods it will target with retaliatory tariffs if US President Donald Trump follows through on his threat to impose duties on steel and aluminum exports,

Canada supplies roughly 60% to 70% of the imports that come into the U.S. market. Canadian suppliers like Rio Tinto produce high quality aluminum that is typically sold to stateside buyers.

US President Donald Trump has enacted a new 25% tariff on steel and aluminum imports, a move affecting all countries worldwide. This major shift in policy is expected to have a particularly harsh impact on Canada, eliciting sharp critiques from Canadian leaders.
