To date, Trump’s tariffs have targeted Canadian goods that include steel, aluminum, energy and the auto industry. After threatening a 50% tariff early last week on the country’s steel and aluminum, he reduced it to 25% days later after Canada retaliated, then pushed to April 2 the full 50% tariff.

Trump and his aides have reportedly threatened to redraw the northern border, go after Canada’s minerals and water, and cancel NORAD.

Canada's new tariffs are in addition to its 25% counter tariffs on $30 billion Canadian of imports from the US that were put in place on 4 March in response to other Trump import taxes that he’s partially delayed by a month.
