Donald Trump reimposes tariffs on raw Canadian aluminum, Canada promises retaliation

President Donald Trump on Thursday moved to reimpose 10 per cent tariffs on some Canadian aluminum products to protect US industry from a “surge” in imports, angering Ottawa and some US business groups.

Canada pledged retaliation as tensions heightened between the close allies just weeks after a new continental trade deal between the United States, Mexico and Canada came into effect.

During a speech at a Whirlpool Corp washing machine factory in Ohio to tout his “America First” trade agenda, Trump said he signed a proclamation reimposing the “Section 232” national security tariffs. The step was “absolutely necessary to defend our aluminum industry,” he said.
