The US president says Canada "wants the benefits of being a state, without being one", accusing the northern neighbours of taking advantage of American farmers "for many years".
"That's enough!" said Donald Trump on Sunday after Canadian Prime Minister Mark Carney announced retaliatory measures against U.S. tariffs following the failure of trade negotiations between the two countries.
After the failure of final negotiations on Saturday, August 22, Canada announces retaliatory tariffs starting September 8, which will correspond to the US "tariffs", "dollar for dollar".
