Steep U.S. tariffs on Canadian and Mexican goods came into effect Tuesday as a deadline to avert President Donald Trump's levies passed without the North American neighbors striking a deal.

Canadian goods will face a 25 percent tariff -- with energy resources hit by a lower 10 percent rate -- while Mexican products face a 25 percent blanket levy, according to orders Trump previously signed. He cited a lack of progress in tackling drug trafficking as he pushed ahead with the duties.
