US Escalates Canada Trade War With New Bans on Dairy, Alcohol and Motorbikes

The trade war between the United States and Canada has entered a new phase, with President Donald Trump ordering a ban on several Canadian products including alcoholic drinks, dairy goods and motorcycles, just as Canada’s latest retaliatory tariffs on American goods came into force.

The latest US restrictions will begin on September 29, while some additional US tariffs announced alongside the bans will take effect earlier, on September 15. The measures mark another escalation in a dispute that has intensified through several rounds of tariffs and failed negotiations.

The latest developments can be traced back to August, when the Trump administration imposed 50% tariffs on about $20 billion worth of Canadian goods after trade negotiations between Washington and Ottawa broke down. The tariffs targeted a range of Canadian products and came after months of increasingly tense discussions between the two countries.

Canada responded by preparing its own countermeasures. Those retaliatory tariffs, covering around $20 billion of US imports, came into force shortly after midnight on September 8. They include duties ranging from 15% to 50% on hundreds of American products, including agricultural goods, steel, aluminium, appliances and other manufactured products.

Trump’s latest response came the same day. His administration announced that from September 29, the US will prohibit imports of a range of Canadian alcoholic beverages, including various beers, wines and spirits, as well as certain dairy products and motorcycles. Some additional Canadian products, including cheeses, paper, furniture, aluminium and other goods, will instead face higher tariffs from September 15.

Washington says the measures are a response to what it describes as discriminatory Canadian trade policies. Trump has repeatedly criticised Canada’s system for protecting sectors such as dairy, where production controls, pricing arrangements and import limits restrict access for some US producers.

Canada disputes Washington’s approach and has signalled that it intends to reduce its dependence on the American market rather than simply accept further US demands. Prime Minister Mark Carney said Canada has the ability to diversify its economy and expand trade with other countries, although he acknowledged that moving away from the US will come with economic costs.

The dispute is particularly significant because the US and Canada have one of the world’s most integrated trading relationships. Canada sends the majority of its goods exports to the United States, while Canadian industries are deeply connected to American supply chains. That means prolonged tariffs can affect manufacturers, farmers, retailers and consumers on both sides of the border.

Businesses are already facing uncertainty over higher costs and reduced access to customers. Canadian companies that rely heavily on US buyers could be particularly exposed, while American businesses that depend on Canadian raw materials and manufactured goods may also face higher costs.

The conflict has also raised concerns about the future of the US-Mexico-Canada Agreement (USMCA), the North American trade pact that replaced NAFTA. Trade negotiations between Washington and Ottawa collapsed in late August, and there is currently no new round of formal talks scheduled.

Despite the escalation, officials on both sides have indicated that a negotiated agreement remains possible. US Trade Representative Jamieson Greer and Canadian officials have continued communicating, but the latest tariffs and import bans have made a quick settlement more difficult.
