President Donald Trump imposed tariffs on $20 billion of Canadian imports, leading to a trade dispute where Canada responded with $20 billion in retaliatory tariffs. In a subsequent adjustment effective October 30, Trump exempted specific Canadian goods—including plywood, machinery, and refrigeration equipment—from 50% tariffs.
These exemptions are described as an effort to support Republican Senator Susan Collins in her reelection bid in Maine. Simultaneously, the U.S. imposed 50% tariffs on other Canadian products, such as shampoo, vinyl flooring, and carpet.
