History Says What the 2025 Auto Tariffs Cost General Motors, and Canada's Rate Is About to Double

President Trump announced tariffs on Canadian vehicles will jump to 50% on January 1, 2027, up from the current 25% rate. GM stock showed minimal reaction, buoyed by the company's track record from the previous tariff cycle when it absorbed $3.1 billion in costs—well below the initial $5 billion forecast—and offset more than 40% through pricing power and manufacturing shifts.

The automaker has since reduced its Canadian manufacturing exposure and raised profit guidance twice in 2026, positioning itself to weather the rate increase. The tariff escalation applies to vehicles manufactured in Canada and imported into the U.S., but GM's operational adjustments since the first round suggest the company is better insulated than in prior cycles.

The market's muted response reflects confidence that GM can replicate its previous playbook: absorbing incremental costs through supply chain reconfiguration and passing select increases to consumers without materially denting margins.
