The Gist
The author argues that despite alarming headlines, the US-Canada tariff dispute is currently minor since it only affects a small slice of their huge trading relationship. However, the author warns that things could get much worse in January when tariffs expand to cover cars and trucks, potentially sparking a real trade war if Canada retaliates and no deal is reached. The piece also criticizes the tariffs for unfairly punishing companies that built US-compliant supply chains under trade agreement rules, sometimes making them pay more than competitors overseas.
Conclusion
The current US-Canada tariff dispute is only a limited skirmish, not a full trade war, but without a negotiated deal by January 2026, escalating tariffs (especially on autos) and Canadian retaliation could trigger a genuine, costly trade war.
Premises
- The Section 338 tariffs (50% on ~$20 billion of Canadian goods) and Canada's retaliatory tariffs (~$20 billion) together affect only about $40 billion of the roughly $900 billion in annual US-Canada trade, meaning ~95% of trade continues unaffected.
- Starting in January, 50% tariffs will expand to many more Canadian exports including cars, trucks, and auto parts, potentially affecting over $100 billion in trade when combined with Canadian retaliation.
- The Section 338 tariffs violate the previous USMCA carveout principle by applying regardless of USMCA compliance, punishing companies that invested billions to build compliant North American supply chains in good faith.
- This creates perverse outcomes where USMCA-compliant products (e.g., Canadian steel used in US manufacturing) face higher effective tariffs than goods made entirely in China or Korea, undermining the tariffs' stated purpose of boosting American production.
- Protectionist lobbies (especially Canada's dairy lobby) and Canada's trade ties with China are obstacructing a mutually beneficial deal.
- A trade deal that reduces trade barriers and opens markets would lower manufacturing costs and consumer prices through efficiency and competition, whereas a full trade war benefits no one.
Assumptions
- The dollar value of trade affected is an adequate proxy for the severity/impact of a 'trade war' versus a 'skirmish.'
- USMCA-compliance carveouts represent a fair and appropriate baseline for tariff policy that should not be violated.
- Reducing trade barriers on both sides would necessarily lead to lower costs/prices rather than other economic disruptions.
- The January tariff escalation and Canadian retaliation are likely to occur as threatened absent a deal.
- Political will exists to reach a deal if not obstructed by lobbies, implying the obstacles are primarily political rather than structural economic conflicts of interest.
