Trump's latest Canada tariff threat puts a C$40.8 billion mechanical upper bound on the annual auto-trade bill. That estimate applies the threatened 50% rate to C$81.6 billion of 2024 Canadian vehicle and parts exports. It is a stress test, not a forecast.
The tariff threat is months away. The equity reaction is already here, because Canadian parts feed U.S. assembly and can cross the border more than once.
C$40.8bn is a transparent ceiling: 50% of the full 2024 export value. Content-based treatment, exemptions or a deal would lower the realized duty. Repeated border crossings can still multiply operating disruption.

| Full escalation | Final order covers full customs value | Margins, output and sticker prices |
| Retaliation loop | Broader Canadian list after 8 Sep | US exporters and cross-border demand |
