Trade tensions between the United States and Canada escalated following the collapse of commercial negotiations. The U.S. government announced 50% tariffs on approximately $20 billion in Canadian goods, representing about 5.5% of Canadian exports to the U.S.

In response, Canadian Prime Minister Mark Carney suspended trade talks, citing “unfair and non-economic last-minute changes” to U.S. terms. Canada has scheduled September 8 as the start date for its own retaliatory penalties.
