The trade relationship between the United States and Canada remains in a state of persistent friction, with no clear resolution in sight more than 18 months after President Donald Trump returned to the White House and initiated a broad global tariff program. Canada, one of the first nations targeted by these measures, has responded with its own reciprocal actions, marking a significant escalation in a conflict that continues to impact key industries across North America.
The US government has placed tariffs on essential Canadian sectors, including steel, aluminum, lumber, and automobiles. Most recently, Washington imposed an additional 50% levy on approximately C$28bn ($20bn; £15bn) worth of Canadian goods. In response, Ottawa announced a strategic, dollar-for-dollar retaliation on Tuesday, targeting American products to match the financial impact of the US measures.
The regional consequences of these policies are becoming increasingly visible. In Canada, Ontario has faced significant hardship due to its reliance on manufacturing, with numerous auto parts and assembly plants forced to implement production cuts and layoffs. Estimates suggest the province has shed tens of thousands of manufacturing jobs since the start of 2025. Quebec has also seen a sharp decline in its metal sector, with exports of steel, copper, and aluminum dropping 36% between February 2025 and February 2026, accompanied by a 3.6% reduction in sectoral employment.
While the new US tariffs that took effect on August 22 are expected to affect every province, the impact will be most severe in British Columbia, Quebec, and Ontario. Bank of Canada data indicates that roughly 55,000 manufacturing jobs were lost across the country between January 2025 and January 2026. Economist Trevor Tombe of Calgary warns that if these 50% tariffs persist, the total number of lost jobs could climb to 90,000. Furthermore, an analysis commissioned by the Canadian American Business Council suggests that a failure of the USMCA trade agreement would lead to tens of thousands of additional job losses in directly affected manufacturing industries.
On the American side, the economic fallout is distributed differently. Canada’s retaliatory tariffs, which cover C$28bn in US goods ranging from furniture and cosmetics to toilet paper, are specifically aimed at swing states. Ohio is expected to bear the brunt, with 12% of its exports—totaling C$3.2bn—facing new taxes, particularly on steel and laundry machines. Illinois and Pennsylvania are also slated for significant impacts, with Illinois facing new levies on farm and construction equipment, a sector dominated by companies like John Deere. Scotiabank economist Derek Holt noted that these counter-tariffs appear deliberately oriented toward states that could prove decisive in upcoming midterm elections.
Beyond specific regional impacts, the broader economic landscape is shifting. The average effective US tariff rate on Canadian goods has nearly doubled, rising from 2.9% in June to 5.7% currently, according to the Royal Bank of Canada. While this remains lower than the 6.2% rate applied to the UK or the 20.5% average faced by China, it represents a notable departure from Canada’s previous status as a low-tariff partner. The Tax Foundation estimates that the average American household could face an additional $840 in costs this year due to these broader trade policies, while the Center for American Progress reports that tens of thousands of US jobs have been lost in manufacturing, transportation, and warehousing due to the administration’s global tariff program.
Canadian businesses are increasingly looking beyond the US market to mitigate these losses. While the US historically accounts for more than 70% of Canadian exports, firms are diversifying their reach. Prime Minister Carney has committed to doubling non-US exports over the next decade, and Bank of Canada data shows a rise in exports to other nations since early 2025. Some entrepreneurs, such as Toronto-based menswear owner Matteo Sgaramella, have successfully pivoted to European markets, noting that foreign retailers are often eager to support Canadian products as a form of solidarity against the current trade climate.
However, diversification remains difficult for regions deeply integrated with the US economy. A report from the Canadian Chamber of Commerce identified Oshawa, London, and Kitchener-Cambridge-Waterloo as particularly vulnerable, noting that growth in non-US exports has been insufficient to offset the decline in trade activity within these manufacturing hubs. As the dispute continues, the long-term stability of the integrated North American supply chain remains in question. The report also notes that and unleashed a wide-ranging global programme of tariffs, tensions have been simmering between the two neighbours since President Donald Trump returned to the White House just over 18 months ago. The report also notes that here are five charts to help break it all down. The report also notes that with tariffs levied on C$28bn worth of US goods from steel to furniture, cosmetics and toilet paper, as of 8 September, but some states will feel the pain of Canada’s retaliation more than others. The report also notes that from the lowest tariff rates to one with the pack. The report also notes that china still faces the highest US tariffs at an average of around 20.5%. The report also notes that canada, by the happenstance of being neighbours with the world’s largest economy, is hugely reliant on US trade.
