In a high-stakes diplomatic race, Prime Minister Mark Carney and Canadian negotiators are striving to prevent the implementation of new U.S. tariffs on an estimated $20 billion worth of Canadian goods. With three potential outcomes on the horizon—an agreement, a postponement of tariffs, or, in the worst-case scenario, an outright failure to reach any accord—the stakes could not be higher. Should the latter occur, U.S. President Donald Trump has pledged to impose a staggering 50 per cent tariff on numerous products, including electronics, textiles, furniture, and alcohol, beginning Wednesday at midnight. The President has invoked Section 338 of the Depression-era Tariff Act, which permits punitive tariffs on countries perceived to be unfairly restricting U.S. imports, particularly in sectors like automobiles, alcohol, and dairy.
Economic Implications for Canada
While the immediate impact from Section 338 tariffs might appear limited—affecting only 5 per cent of Canada’s exports to the U.S.—the broader economic ramifications could be more profound. Royal Bank of Canada estimates that the tariffs could reduce Canada’s GDP by 0.4 per cent, while Capital Economics puts the figure slightly higher at 0.6 per cent. Despite these seemingly modest numbers, a sharp decline in affected exports could push an already sluggish GDP growth rate perilously close to zero.
The first quarter of 2024 saw Canada’s economy struggle, with a second consecutive decline in annualised growth. However, forecasts suggest a potential rebound as second-quarter figures are anticipated later this month. Nonetheless, certain sectors will likely bear the brunt of the tariffs, with approximately 20 per cent of production and jobs in industries such as apparel and electrical equipment at serious risk.
Products and Industries Most at Risk
Since Trump unveiled the Section 338 hit list in July, attention has been drawn to uniquely Canadian products, including hockey sticks and skates. However, the potential tariffs on electronics and electrical equipment, valued at around $4.4 billion annually, pose a far greater threat. Leading firms within this sector have already warned that a 50 per cent tariff would be catastrophic.
Furniture manufacturers are similarly bracing for a decline in orders, while about 30 per cent of U.S. imports of Canadian dairy products are vulnerable. The alcohol sector is also significantly exposed, with many companies already fielding inquiries from analysts regarding the tariffs’ implications. For instance, Dino Bianco, CEO of tissue-paper manufacturer Kruger Products Ltd., indicated that approximately 1 per cent of the company’s total sales could be affected. In the apparel domain, the tariff list includes down jackets, seemingly targeting brands like Canada Goose Inc. The company reported a 14.1 per cent decline in stock value following the announcement of the tariffs.
Regional Impact of Tariffs
Three provinces are set to feel the most significant repercussions from the proposed tariffs: Quebec, British Columbia, and Ontario. British Columbia could see approximately 14.5 per cent of its shipments to the U.S. impacted, with the lumber and electronics sectors facing the most severe challenges.
Ontario, being Canada’s largest economy and manufacturing heartland, would shoulder the greatest absolute burden, accounting for over half of all U.S. imports from Canada that would be affected by the tariffs. Quebec, already grappling with the highest effective tariff rate for goods shipped to the U.S., stands to see its rate escalate from about 7 per cent to 11 per cent, particularly affecting its dairy, furniture, electronics, and paperboard industries.
In stark contrast, the Prairie provinces appear to be largely insulated from the fallout, as Trump’s tariffs do not target energy and potash imports, meaning that less than 1 per cent of Alberta and Saskatchewan’s exports would incur Section 338 duties.
Potential for Canadian Retaliation
The Canadian government has indicated a willingness to retaliate if the tariffs come into effect, although specific strategies remain under wraps. Prime Minister Carney has dismissed the idea of restricting oil exports to the U.S., yet a range of alternatives is still being considered. Previously, Canada imposed three rounds of countertariffs on over $90 billion worth of U.S. goods, with tariffs set at 25 per cent on various items, from orange juice to motorcycles.
In September 2025, Ottawa lifted approximately half of these tariffs in an effort to facilitate trade discussions, but retained tariffs on U.S. steel, aluminium, and automobiles. Should Canada choose to reinstate these levies, it would undoubtedly impact U.S. exporters but would also lead to increased costs for Canadian consumers. A Bank of Canada study indicated that prices for tariffed goods rose by about 6 per cent, implying that a portion of the tariff burden was passed on to consumers.
However, the risk of escalating tensions is palpable, as U.S. trade officials have made it clear that they would not tolerate retaliation, warning of swift consequences.
Impact on Broader Trade Relations
The looming threat of Section 338 tariffs has resulted in renewed negotiations between Canadian and U.S. officials after a period of stagnation. If an agreement is not reached and the tariffs take effect, it could significantly stall ongoing discussions concerning the future of the United States-Mexico-Canada Agreement (USMCA). Canada’s chief negotiator, Janice Charette, has characterised the tariffs as a potential deal-breaker, suggesting that further negotiations would be untenable if the tariffs are imposed.
A successful resolution could pave the way for deeper conversations regarding the USMCA, particularly concerning rules of origin for automobiles and other goods. However, a breakdown in negotiations could jeopardise the entire agreement and limit future collaboration on essential issues like energy and defence. Prime Minister Carney has expressed interest in a “Fortress North America” strategy in critical sectors, yet the imposition of Section 338 tariffs could widen the rift he has often referenced.
Why it Matters
The unfolding trade conflict has significant implications not only for Canadian industries and regional economies but also for the broader relationship between Canada and the United States. With the potential for retaliatory measures and heightened tensions, the stakes are incredibly high. A failure to resolve these issues could further complicate future trade negotiations, diminishing prospects for collaboration on critical continental issues. As both nations grapple with these challenges, a fragile equilibrium hangs in the balance, making the coming days crucial for the future of transnational trade and economic stability.
