Steel tariffs of 25 per cent on “foreign steel” were announced by American President Donald Trump this afternoon.
“Our industries have been targeted for years and years by unfair foreign trading practices”
Aluminium imports into the United States will also be subject to a tariff, at the rate of 10 per cent.

Canada, which sells about 90 per cent of the steel produced in this country to the United States, is exempt for now.
Trump said that while the North American Free Trade Agreement (NAFTA) is being re-negotiated, Canada and Mexico will be exempt.
If, however, the negotiations do not go in the direction the U.S. president wants, then the NAFTA will be “torn up” and steel and aluminum tariffs will be imposed.
$15 billion of the two metals combined were exported to the U.S. last year.
In the event of a breakdown over NAFTA, these tariffs would likely bring swift retaliatory tariffs on U.S. goods imported into Canada.
“Our industries have been targeted for years and years by unfair foreign trading practices,” Trump said at the televised signing ceremony, “And that’s going to stop.”
Mark Warner, trade lawyer and principal at MAAW Law in Toronto, referred to the temporary exemption as “a minor victory”.
“This is on balance a good thing today,” he said in an interview this afternoon with CBC News Network.
“We didn’t get caught up in the application of this thing,” but it will likely loom large in the background of NAFTA discussions.
“We’ll see how far this really goes,” he said. “When you take Canada and Mexico out of the equation, you’re taking an awful lot of American steel imports out …. Realistically, is that enough left over there to really ramp up American production in a significant way? Probably not.”
