Background and impact
US–Canada trade tensions have escalated since talks collapsed in mid-August: Washington imposed 50% tariffs on hundreds of Canadian items (wine, cement, etc.) on August 22, and Ottawa announced and implemented matching retaliation on September 8. Canada said the package also includes support for businesses and workers and encourages consumers to buy Canadian-made products. CTV News reports that no formal trade talks between the two countries are currently taking place.
