Automotive
StormVehicle manufacturing, parts production, and cross-border supply chains. Canada and the U.S. share deeply integrated auto production — parts cross the border up to eight times during assembly.
The most severely affected industry. A 25% Section 232 tariff on non-CUSMA content has been in force since April 2025. In August 2026, Section 338 added a separate 50% tariff on Canadian motor vehicles. The Big Three have idled Canadian production lines. Bilateral auto negotiations are ongoing but unresolved.
In Force
Measures currently active since the 2025 escalation.
Section 232 Tariff on Automobiles (25% on non-CUSMA content)
In ForceSection 232 national security authority. The non-U.S. content rule creates complex compliance calculations for manufacturers with multi-country supply chains.
10% Global Tariff on Non-CUSMA Goods
In ForceReplaced the IEEPA 25%/10% tariffs struck down by the Supreme Court in February 2026. Lower rate but broader legal footing. Businesses that paid IEEPA tariffs between Feb 2025 and Feb 2026 became eligible for refunds.
Section 338 Tariff — Dairy, Alcohol, and Motor Vehicles (50%)
In ForceFirst use of Section 338 of the Tariff Act of 1930. Three separate proclamations targeting dairy (quotas), alcohol (provincial restrictions), and motor vehicles (retaliatory tariffs). Brief 3-day pause Aug 19–22 after announced deal, which collapsed. Total exposure ~$20B, covering ~5.2% of U.S. imports from Canada.
Forecast
Threatened, announced, or scheduled — not yet in force.
Section 232 — 50% Auto and Steel Tariff Increase (Jan 1, 2027 Threat)
ThreatenedTrump announced August 24, 2026 that tariffs on Canadian automobiles, auto parts, and steel will rise to 50% on January 1, 2027. The auto rate increase (from 25%) would make Canadian assembly largely unviable. Stellantis is reportedly considering closure of its Brampton Assembly Plant. Announced after trade talks collapsed on August 21.
CUSMA/USMCA Joint Review — U.S. Declines to Extend
Under NegotiationOn July 1, 2026, the U.S. declined to confirm extension. Agreement remains fully in force but faces annual review. Canada has not yet begun substantive text-based negotiations with the U.S. This creates structural uncertainty for all cross-border trade.
Canadian Response
Actions Canada has taken or is pursuing.
Retaliatory Tariffs on U.S. Steel, Aluminum, and Consumer Goods (C$29.8B)
Canada imposed 25% counter-tariffs on C$29.8 billion of U.S. goods including steel, aluminum, orange juice, bourbon, and household appliances. Product list designed to target politically sensitive U.S. states.

Canada announced 15–50% counter-tariffs on $27.6 billion of U.S. imports effective September 8, 2026, covering approximately 874 tariff items. Dollar-for-dollar match to U.S. Section 338 tariffs.
Auto Sector Bilateral Negotiations
Ongoing bilateral discussions focused on preserving integrated North American auto manufacturing. Canada seeking sector-specific tariff relief. Daily discussions between Carney and Trump officials intensified in August 2026.
