The recent federal court ruling invalidating President Trump's IEEPA tariffs has upended the U.S.-Canada trade relationship, creating both opportunities and risks for investors. With key sectors like steel, autos, and semiconductors now free from certain trade barriers, strategic moves could yield significant returns—if acted on swiftly. However, lingering Section 232 tariffs and the specter of appeals threaten to prolong uncertainty. Here's how to position your portfolio for this evolving landscape.
The court's invalidation of IEEPA tariffs has removed a major drag on cross-border steel flows, particularly from Canada. Canadian steelmakers, which faced punitive duties under the now-stricken “Liberation Day” tariffs, now operate in a more normalized trading environment. U.S. buyers, too, may see reduced costs for Canadian raw materials, easing pressure on manufacturers.
However, the Section 232 tariffs—still at a steep 25%—remain a thorn in the side of the industry. These duties, imposed under the Trade Expansion Act, are a residual risk that could limit the full rebound of global supply chains. Investors should focus on Canadian steel stocks like ArcelorMittal or Stelco, which were unfairly penalized under the IEEPA regime and now trade at discounts to their U.S. peers.

The removal of IEEPA tariffs on auto parts has been a lifeline for U.S. automakers, which relied heavily on Canadian suppliers for components like engines and wiring. Companies such as General Motors (GM) and Ford (F) now face reduced costs, potentially boosting margins. The U.S.-Canada auto trade, which saw $64 billion in bilateral trade in 2024, is poised for growth as cross-border logistics normalize.
Yet, the Section 232 tariffs on automotive parts—still in effect—pose a ceiling. These duties, combined with the administration's ongoing negotiations over fentanyl and migration, mean volatility could resurface. Investors should pair exposure to U.S. automakers with Canadian auto suppliers like Linamar or Martinrea International, which benefit from reduced trade friction while maintaining geographic diversification.
The court's ruling has eliminated IEEPA tariffs on semiconductors, a critical sector for both nations. U.S. tech giants like Intel (INTC) and AMD (AMD), which source components from Canadian manufacturers, now face fewer barriers. The removal of these tariffs could accelerate innovation and investment in semiconductor fabrication, particularly in regions like Ontario, where companies like Xperi Corporation operate.
However, the U.S. government's focus on decoupling from Chinese tech and its push for domestic production (via the CHIPS Act) adds complexity. Investors should balance exposure to U.S. semiconductor leaders with plays on Canadian firms positioned to supply this growing market.
While the court ruling has cleared some trade hurdles, the administration's appeal and ongoing U.S.-Canada negotiations mean uncertainty persists. To mitigate risk:
The window to capitalize on reduced trade barriers is narrowing. The administration's appeal of the court ruling could re-impose IEEPA tariffs, while negotiations over fentanyl and migration add further layers of risk. Investors who delay risk missing the rebound in steel, autos, and semiconductors.
Final Recommendation:
- Buy: Canadian steel stocks (Stelco), U.S. automakers (GM), and semiconductor leaders (AMD).
- Hedge: Use put options on tariff-exposed equities and allocate 10% to gold.
The court's decision has redrawn the trade map—but only the swift will profit.
