The U.S. government announced it will ban imports of some Canadian dairy products and alcoholic drinks. This move came one day after Canada imposed taxes—called tariffs—on around $20 billion of American products. These tariffs ranged from 15% to 50%, meaning American goods entering Canada will suddenly cost much more.
When one country taxes another's goods, the other country often fights back by doing the same thing. That's what's happening here. The U.S. is responding to Canada's tariffs by blocking Canadian products from entering America. For consumers, this can mean higher prices on cheese, milk, and drinks, since companies that sell these items now face added costs.
