Celebrations in Canada were brief and restrained after the US Supreme Court struck down President Donald Trump’s global tariffs, including the so-called “fentanyl tariffs” targeting Canada, China, and Mexico.
While the ruling reinforced Ottawa’s long-standing position that the levies were “unjustified,” Canadian officials were quick to caution that significant trade challenges remain particularly in key sectors like steel, aluminum, and automobiles.
A Legal Win — But Limited Immediate Impact
Canada had faced tariffs of 25%, later raised to 35%, under measures introduced by the Trump administration. The justification was that Canada and Mexico needed to do more to stop migration and the flow of fentanyl into the United States.
However, the real economic impact of those “fentanyl” tariffs had already been muted. Roughly 85% of trade covered by the measures remained tariff-free due to exemptions under the United States–Mexico–Canada Agreement (USMCA).
Following the Supreme Court’s decision to strike down the tariffs imposed under the International Emergency Economic Powers Act (IEEPA), the White House introduced a new 10% global tariff. It later announced that the rate would rise to 15%.
Crucially, the USMCA exemption remains in place under the new tariff structure — meaning much of Canada’s trade remains protected for now.
USMCA Review: The Bigger Battle Ahead
The most pressing issue on Canada’s trade agenda is the upcoming review of the United States–Mexico–Canada Agreement, negotiated during Trump’s first term. The agreement governs a market of more than 500 million people and underpins deeply integrated North American supply chains that have existed since the early 1990s.
This summer, Canada, Mexico, and the United States must decide whether to extend the deal.
Canada has expressed strong support for maintaining a trilateral agreement. However, officials in Washington have signaled that the US may prefer separate bilateral deals instead.
Canadian Trade Minister Dominic LeBlanc is expected to meet US Trade Representative Jamieson Greer in the coming weeks potentially marking the first formal trade discussions since talks were halted last October. At the time, Trump suspended negotiations after objecting to an anti-tariff advertisement sponsored by Ontario that aired in the US.
Ongoing Trade Frictions
Despite the court ruling, tensions remain:
- Tariffs on steel, aluminum, and automobiles are still in place.
- US officials have criticized Canadian restrictions on wine and spirits sales.
- Dairy import quotas remain a longstanding point of contention.
- Canada’s Online Streaming Act, which requires companies like Netflix and Spotify to contribute to Canadian content funding, has also drawn US objections.
Greer recently described negotiations with Canada as “more challenging” than with Mexico, citing unresolved barriers and regulatory differences.
Diversifying Beyond the US
With roughly 75% of Canadian exports heading to the US, Ottawa is seeking to reduce dependency. The government has set a goal of doubling non-US exports by 2035, expanding trade relationships in Europe and Asia.
Business leaders, however, remain cautious.
Dennis Darby, CEO of Canadian Manufacturers & Exporters, emphasized that businesses need certainty. “Predictable, rules-based trade is essential,” he said, underscoring industry hopes for a stable USMCA renewal that ends recurring disruptions.

FAQs
Why did the US Supreme Court strike down Trump’s tariffs?
The court ruled that the administration overstepped its authority under the International Emergency Economic Powers Act (IEEPA), invalidating the legal basis for the tariffs.
Does this mean Canada is free from US tariffs?
Not entirely. While the specific tariffs under IEEPA were struck down, sector-specific tariffs on steel, aluminum, and automobiles remain. A new 10–15% global tariff has also been introduced, though USMCA exemptions continue.
What is the USMCA and why is it important?
The USMCA is the North American trade agreement between the US, Canada, and Mexico. It facilitates tariff-free trade across most sectors and supports highly integrated supply chains across the continent.
Why are trade talks between the US and Canada tense?
Disputes include dairy market access, alcohol sales restrictions, digital streaming regulations, and broader regulatory differences. Political tensions have also complicated negotiations.
What happens if the USMCA is not renewed?
Failure to renew could lead to new tariffs, trade uncertainty, and disruption to industries like automotive manufacturing, agriculture, and energy that rely on cross-border integration.
Conclusion
The US Supreme Court’s decision delivered Canada a symbolic and legal victory — but not a sweeping economic breakthrough.
With sector-specific tariffs still intact and the USMCA review looming, the real test lies ahead. Canada faces a delicate balancing act: defending its domestic policies while preserving access to its largest trading partner.
Whether North America maintains a unified trade bloc or shifts toward bilateral arrangements will shape economic relations for years to come. For Canadian businesses, the priority remains clear: stability, predictability, and a renewed commitment to rules-based trade.
