## Prediction

Over the next seven days, the ongoing US–Canada trade confrontation will start to spill into defense-industrial and critical mineral supply chains, as both sides deploy targeted tariffs, export controls, or procurement preferences affecting dual-use goods. Cross-border defense projects and EV battery supply chains drawing on Canadian critical minerals will face heightened uncertainty, prompting firms to model relocation and diversification scenarios. This will complicate North American efforts to onshore defense production and reduce dependence on China. Confirmation would be new trade measures explicitly touching aerospace, defense, or battery materials; denial would be a rapid, negotiated de-escalation or carve-outs insulating these sectors.

## Drivers

- Emerging trend: Canada–US trade rupture fracturing North American economic security architecture
- Existing disputes already affecting broader economic and defense cooperation
- Integration of Canadian critical minerals into US strategic supply chains
