Canada struck back at the United States on Tuesday with retaliatory tariffs on about $20 billion worth of American goods, including steel, dairy products, appliances and farm equipment, as the trade war between the once-friendly neighbors escalated sharply.
The tension threatened one of the world’s largest trading relationships. The new tariffs extended well beyond industrial goods, hitting everyday purchases such as seafood, cheese, clothing, cosmetics and toilet paper, with some facing duties as high as 50%.
