Trade Relationship Overview
Canada and the US share the world's most extensive bilateral trading relationship, underpinned by USMCA (and its predecessor NAFTA before 2020). For decades, this meant near-frictionless trade with 0% duty on the vast majority of qualifying goods. However, the relationship has experienced unusual volatility in recent years, with the US imposing tariffs on specific Canadian sectors (notably steel, aluminum, and at times broader categories) citing national security or trade balance concerns — moves that fall outside the normal USMCA framework and have prompted Canadian retaliatory measures.
This makes Canada-US trade unusual: the underlying legal framework (USMCA) still provides for 0% duty on qualifying goods, but real-world applied rates for specific sectors can shift suddenly based on broader political and trade policy dynamics.
Current Tariff Landscape by Sector
| Category | HS Chapter | USMCA Rate (Qualifying) | Special Measures Risk |
|---|---|---|---|
| Steel Products | 72–73 | 0% | Subject to periodic Section 232 measures |
| Aluminum Products | 76 | 0% | Subject to periodic Section 232 measures |
| Lumber/Softwood | 44 | Varies + AD/CVD | Long-running softwood lumber dispute |
| Automotive & Parts | 87 | 0% (if RVC met) | Generally stable under USMCA |
| Agricultural Products | various | 0% (mostly) | Dairy subject to tariff-rate quotas |
| Energy Products | 27 | 0% | Generally stable, occasional policy attention |
Unlike most USMCA trade, certain sectors — particularly steel, aluminum, and lumber — have experienced tariff actions outside the normal USMCA tariff-free framework, citing national security (Section 232) or anti-dumping/countervailing concerns. These measures can be imposed, modified, or lifted with limited advance notice. If you're sourcing in an affected sector, build flexibility into your supply chain and monitor official trade policy announcements closely.

Why Canada-US Trade Remains Attractive Despite Volatility
- Fastest transit times of any major trade route — 2–5 days by truck
- Deeply integrated supply chains — especially in automotive, where parts often cross the border multiple times during production
- Shared regulatory standards in many sectors, reducing compliance complexity
- USMCA's underlying framework remains intact — sector-specific measures are exceptions, not a wholesale change to the trade relationship
