Canada Fires Back at Trump as 50% Tariffs Hit U.S. Goods in Escalating Trade War

Canada has fired its latest economic shot at the United States, imposing tariffs of up to 50% on hundreds of American products as the bitter trade war between Ottawa and Washington enters a dangerous new phase.

The retaliatory tariffs took effect at 12:01 a.m. Eastern Time on September 8, targeting about C$27.6 billion (approximately US$20 billion) worth of U.S. imports. The measures cover roughly 700 products, with tariffs ranging from 15% to 50%.

The move comes after negotiations between the two countries collapsed and follows the Trump administration’s decision to impose matching 50% tariffs on a similar value of Canadian goods.

Canada has described its response as a “dollar-for-dollar” retaliation.

U.S. Milk, Perfume and Golf Equipment Among Targets

The new Canadian tariffs hit a surprisingly broad collection of American products.

Certain U.S. dairy products, including milk, face tariffs of up to 50%, while cheese and some household appliances are among products subject to 25% duties. Clothing, furniture, steel and aluminum products are also among the goods facing the highest tariff rate.

The list also includes consumer and recreational products such as perfume, golf equipment and other manufactured goods.

Canada initially included additional seafood products in its retaliation package but subsequently removed some seafood items after concerns from its domestic fishing industry.

The changes highlight the economic dilemma facing Ottawa: retaliating against Washington without unnecessarily damaging Canadian businesses that depend on cross-border supply chains.

Trump Trade War Is Now Hitting Both Sides

The latest escalation follows months of increasingly hostile trade relations.

Donald Trump has imposed tariffs on Canadian products while accusing Canada of unfair trade practices. Washington’s latest measures included 50% tariffs affecting about US$20 billion of Canadian imports, prompting Ottawa to prepare an equivalent response.

The latest Canadian counter-tariffs now bring additional pressure on American exporters.

Economists have warned that businesses could ultimately pass higher import costs on to consumers, meaning the trade fight could show up in everything from food and clothing to appliances and furniture.

The affected products represent only a fraction of the enormous commercial relationship between the two countries, but their political impact is far greater.

Canada-U.S. Trade Relationship Under Pressure

The United States and Canada maintain one of the world’s largest bilateral trading relationships, worth hundreds of billions of dollars annually.

That makes the current confrontation particularly significant.

The latest tariff measures also come as uncertainty grows around the future of the USMCA, the North American trade agreement covering the United States, Mexico and Canada, surprisingly also negotiated by Donald Trump in his first term.

Canadian Prime Minister Mark Carney has continued to signal that Ottawa wants a deal but has criticized Washington’s negotiating demands.

Carney has argued that the United States asked for too much while offering too little, particularly around Canada’s ability to pursue trade agreements with other countries.

Bombardier Threat Adds Another Flashpoint

The tariff escalation has now spilled into Canada’s aerospace industry.

Trump has threatened to block or restrict Bombardier aircraft sales in the United States unless the Montreal-based company shifts more manufacturing south of the border.

Bombardier has a significant U.S. footprint, making the dispute particularly complicated for both countries. Trump’s latest threat came as Canada prepared to activate its retaliatory tariffs.

The threat adds another potential front to a trade dispute that is already spreading across manufacturing, agriculture, energy and consumer goods.

Canada Is Preparing for a Longer Fight

Ottawa is not treating the latest tariffs as a short-term confrontation.

The Canadian government has announced billions of dollars in support measures for businesses and workers affected by U.S. tariffs, including a new C$7.5 billion (approximately US$5.4 billion) package of measures.

At the same time, Mark Carney has pushed for Canada to diversify its trading relationships and reduce its dependence on the U.S. market.

That could mark the biggest long-term consequence of the tariff war.

For decades, Canada’s economy has been deeply integrated with the United States. Now, both governments are increasingly talking about resilience, domestic production and alternative trading partners.

The Next Move Could Be Even Bigger

With Canada’s counter-tariffs now active, the biggest question is what Washington does next.

U.S. officials have warned against retaliation and suggested additional restrictions could follow. Trump has also threatened further measures targeting Canadian industries.

For businesses on both sides of the border, that uncertainty may be more damaging than any single tariff.

The trade war has moved beyond a temporary negotiating tactic. It is becoming a structural fight over how the world’s largest bilateral trading relationship will work in the years ahead.

And with tariffs now hitting American goods in Canadian stores, consumers may soon feel the battle far beyond the headlines.
