The US-Canada trade debate has taken a sharper turn after President Donald Trump warned of raising tariffs on Canadian cars, trucks and automotive parts to 50 per cent from January 1, 2027. The move could have significant implications for the deeply integrated North American automotive supply chain, where cross-border movement of vehicles, components and aluminium-intensive parts is central to production. With Canada preparing retaliatory measures, automakers and suppliers now face greater uncertainty over costs, sourcing and investment decisions.
President Donald Trump announced the proposed tariff increase after US-Canada trade negotiations broke down. He also called on companies to manufacture in the US, stating, “Build in the US and there are ZERO TARIFFS.”
The proposed automotive tariff matters because Canada and the US operate an integrated production system rather than two independent automotive markets. As per Global Affairs Canada, Canada exported approximately CAD 80.3 billion (USD 57.95 billion) of motor vehicles and parts in 2024, with nearly 95 per cent of Canadian motor-vehicle and parts exports destined for the US.
This exposure means that a major tariff could affect not only finished vehicles but also the tier-one and tier-two suppliers that provide components, materials and subassemblies to plants on both sides of the border.
