WASHINGTON, United States, Aug 23, 2026 (BSS/AFP) - US President Donald Trump hit back at Canada on Sunday after Prime Minister Mark Carney announced retaliatory tariffs on the United States following a breakdown in trade negotiations.

"Canada wants the benefits of being a State, without being one!!!" Trump said in a post on Truth Social.

"They have also charged our great farmers, for many years, massive amounts of Tariffs. No more!!!" he said.

Carney said Saturday that new Canadian tariffs would take effect on September 8, notably targeting the US steel and dairy industries.

New 50-percent US tariffs impacting about $20 billion worth of goods, or 5.5 percent of Canadian exports to the US, came into force Saturday.
