US-Canada trade war intensifies with new tariffs

President Trump now says he’s doubling the tariffs on Canadian steel and   aluminum to 50 percent. The president has instructed the Commerce Department “to add an additional 25 percent tariff…on all steel and aluminum” imports from Canada effective Wednesday. He wrote on social media that Canada is “one of the highest tariffing nations anywhere in the world.” The president said the increase of the tariffs is a response to the price increases that Ontario put on electricity sold to the United States.
