Canada sets retaliatory US tariffs for September 8

Prime Minister Mark Carney announced the retaliatory measure on Saturday. The available feed reports did not specify the full product list or the total value of affected imports.
Why it matters
Fresh tariffs threaten costs and trade flows across deeply integrated Canadian and US supply chains.
