U.S. President Donald Trump is moving to impose tariffs of 50 per cent on a wide range of Canadian exports, a dramatic ramping up of his trade war against his northern neighbour.

Auto parts, vehicles absent from tariff listThe White House published three lists of Canadian products that will face the new 50 per cent tariff. The Canadian products on the dairy list include milk, cream, other dairy products and molasses. "If these tariffs proceed, Canada should respond tariff for tariff, dollar for dollar," Ford said on social media.
