Canada hits the U.S. with tariffs on $20 billion worth of U.S. exports as trade war escalates

Canada retaliated against the tariffs President Donald Trump has imposed on imports from Canada with tariffs on approximately $20 billion worth of U.S. goods. 

The tariffs impact hundreds of American products, including steel, aluminum, cheese, appliances, clothing, cosmetics and farm equipment, the Associated Press reported. 

The tariff rates run from 15% to 50% and match Washington's tariffs dollar for dollar. They took effect at 12:01 a.m. Tuesday. 

Canadian Prime Minister Mark Carney said U.S. tariffs could severely impact key Canadian industries and limit the country's sovereignty. 

Trump, meanwhile, has warned that Canada's economy could collapse if Carney continued to treat him as an enemy, and the president threatened consequences “worse than anything that has ever happened to a Canadian Politician.”
