The United States announced sweeping bans on imports of Canadian alcoholic beverages, motorcycles and selected dairy products, sharply escalating a trade dispute between two deeply integrated economies. The measures were published by the White House and are scheduled to take effect on September 29.
Washington acted after Canadian retaliatory tariffs on American goods entered into force shortly after midnight on Tuesday. Those levies followed a 50 percent US tariff imposed the previous month on about $20 billion of Canadian products after several rounds of bilateral negotiations failed to produce an agreement.
The American ban appears to cover most alcohol categories, including beer, wine, whisky, bourbon, rum, vodka, vermouth, tequila, mezcal and brandy. It also reaches motorcycles and dairy-related goods such as whey protein and molasses, while several cheeses will face a 50 percent tariff rather than a complete prohibition.
Additional paper, aluminum, wood, furniture and lighting products were added to the higher-tariff list. A previous threat by President Donald Trump to raise duties on Canadian cars, trucks and automotive parts from 25 to 50 percent on January 1 also remains active, extending uncertainty into another major industry.
US Trade Representative Jamieson Greer and Canadian minister Dominic LeBlanc have remained in contact and were expected to speak again about a possible alternative path. Canadian officials said discussions continue on several issues, although formal trade negotiations are not currently taking place.
Ottawa's countermeasures apply duties of between 15 and 50 percent to roughly $20 billion of US goods, from steel and furniture to clothing and electronics. The product selection is designed to create economic and political pressure in competitive states such as Michigan and Ohio before November's midterm elections.
The direct volume affected remains modest beside total bilateral commerce, but the spiral is raising doubts about the US-Mexico-Canada Agreement. Canada sends almost 68 percent of its exports to the United States, and roughly four-fifths of that trade had moved duty-free under exemptions that the latest US legal mechanism does not recognize.
Businesses are already considering adjustments: Sapporo may move limited non-alcoholic beverage production from its Canadian Sleeman operation to the United States, though no decision is final. Mark Carney's approval rose to 62 percent as he urged Canada to diversify, while only 20 percent of Americans approved of Trump's Canadian tariffs in a Reuters/Ipsos poll.
