Trump administration threatens further tariffs on Canadian goods

The United States escalates its trade war with Canada on Tuesday, banning some Canadian dairy products and motorcycles as well as most alcoholic beverages after retaliatory Canadian tariffs took effect on about 20 billion US dollars in American goods.

Canadian Prime Minister Mark Carney says US demands could hollow out key Canadian industries and limit the country's independence, while US President Donald Trump's threats to Canadian sovereignty have rallied the public behind Carney.

Trump also moves to shut Canadian products out of large, long-term US government contracts, broadening the confrontation beyond tariffs as relations between the longtime allies deteriorate further.
