US-Canada trade war escalates

Trade negotiations between the United States and Canada have collapsed, prompting President Trump to impose a 50% tariff on $20 billion worth of Canadian goods.

Canada is poised to unveil retaliatory tariffs and has threatened to cut electricity exports to the US. The dispute has escalated into sharp personal exchanges between Trump and Ontario Premier Doug Ford.

The escalating trade war is expected to have significant economic consequences for both countries.
