U.S.-Canada Trade War Escalates as Ottawa Imposes Tariffs

The U.S.-Canada trade war escalated when Ottawa retaliated with tariffs of its own after Trump slapped 50% tariffs on $20 billion worth of Canadian products. This move came as a surprise to many, given Canada's significant trade relationship with the United States.

Canada buys more from the U.S. than any other country, and most American products enter Canada duty-free under the US-Mexico-Canada Agreement negotiated by President Trump in his first term. However, Canada does protect several domestic industries, including its dairy industry, through a system that imposes tariffs of over 200% on most dairy products once they've exceeded a quota.

Trump claims that Canada is discriminating against U.S. auto, dairy, and alcoholic beverage exports, but critics argue that the U.S. has been making headway in accessing the Canadian market for these products. The U.S. already runs a trade surplus in dairy with its northern neighbor, exporting $1.3 billion worth of dairy products to Canada last year while importing just $585 million.

The U.S.-Canada trade deficit is largely due to Canada's oil exports, which exceed $85 billion annually. Refineries in the U.S. Midwest rely on Canadian crude oil and cannot switch to other sources, as it would require billions of dollars and years of investment.
