Ottawa is cracking down further on imports of foreign steel into Canada to help Canadian mills that have effectively been shut out of the U.S. market by President Donald Trump’s tariffs.

Less than a month ago, the federal government announced that countries such as China and Turkey that don’t have free trade agreements with Canada will face tariffs of 50 per cent if they ship into Canada volumes above 2024 levels.

Prime Minister Mark Carney at a steel manufacturing plant in Hamilton announced that he is tightening that quota now to 50 per cent of 2024 levels.
