## Prediction

Over the next week, political and bureaucratic signaling around prospective new US tariffs on USMCA partners, particularly Canada, will intensify, with Ottawa beginning internal preparations of potential retaliatory tariff lists. Formal measures will likely remain under study rather than implemented, but bilateral rhetoric will harden, featuring statements about defending national interests and leveling the playing field. Mexico will cautiously align with Canada in opposing broad-based measures while trying to protect key export sectors. The dispute will not yet derail USMCA but will inject uncertainty into North American trade policy.

## Drivers

- Warning on planned US tariffs targeting USMCA partners and Canada
- Emerging US trend toward burden-sharing and harder bargaining with allies
- Previous episodes of US–Canada steel/aluminum tariff disputes
