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.
