The United States is slapping 50% tariffs on Canadian products from wine and hockey sticks to cement, in response to Canada’s retaliatory duties on American cars, alcohol, and cheese as part of the two countries’ trade war.

President Donald Trump signed three executive orders on Monday evening to impose the levies on Canada using Section 338 of the Tariff Act, which permits the U.S. to introduce “new or additional duties” of up to 50% on imports from foreign countries that discriminate against or unreasonably burden U.S. commerce.
