## Recent evidence

- [confirms] Washington's Visa Restrictions Slow Brazil Crime Cooperation as Canadian Shoppers Shun American Goods (2026-09-13): Canadian grocers are rebuilding supply chains around domestic producers as consumers boycott American goods, per today's reporting. Retail sourcing decisions made on consumer sentiment rather than tariff schedules embed the decoupling below the policy layer, where a political settlement cannot quickly undo it.
- [confirms] Washington Bans Canadian Dairy, Motorcycles and Most Alcohol as Trade War Widens (2026-09-09): Washington banned imports of Canadian dairy, motorcycles and most alcohol effective September 29, one day after Ottawa's retaliatory duties on roughly $20 billion of American goods took effect. This is the step from tariffs (a price) to outright prohibition (a quantity of zero), which removes the option for importers to absorb the cost and forces physical rerouting of the supply chain.
