A trade dispute between the United States and Canada has intensified following the imposition of new U.S. tariffs. Canada announced it would strike back with its own duties, escalating a trade war after negotiations collapsed.
The U.S. is set to impose 50% tariffs on Canadian goods. In response, Canada stated it would match these levies "dollar for dollar," with its retaliatory measures scheduled to begin on September 8.
Mark Carney stated Canada is now "at war" with the U.S. over trade following the breakdown of talks. This is a developing story and will be updated as details emerge.
