President Donald Trump's 25% tariffs on Mexico and Canada are expected to go into effect on March 4, as critics warn it will drastically raise prices in the U.S.

Trump has vowed to impose 25% tariffs on all imports from Canada and Mexico, with 10% for Canadian energy. CEOs and economists say the action, covering more than $900 billion worth of annual U.S. imports from its southern and northern neighbors would deal a serious setback to the highly integrated North American economy.
