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 rise to 50% on January 1, 2027, doubling the current 25% rate. However, GM's stock showed muted reaction as the company has demonstrated resilience in the previous tariff cycle, absorbing $3.1 billion in costs against a $5 billion forecast and offsetting over 40% through pricing and manufacturing adjustments. GM has also reduced its Canadian footprint and raised profit guidance twice in 2026.
