President Donald Trump said he was increasing the steel and aluminum tariff on Canadian goods to 50% to retaliate against Ontario’s move to place a levy on electricity sent to the US. “This will go into effect TOMORROW MORNING, March 12th,” Trump said in a social media post. The move doubles a planned 25% metals tariff set to take effect just after midnight. Trump said he would also “substantially increase” tariffs on Canadian automobile parts on April 2 if the country does not drop tariffs on dairy products and other US goods. The move risks further upsetting markets, which have posted steady losses since the president moved forward last week with an initial round of tariffs on Canada and Mexico.
