Trump has pledged to impose a 25% tariff on all Canadian imports, due to what he says is inadequate border security and a sizable trade deficit with its northern neighbor. Trudeau and the country's provincial and territorial premiers are in Ottawa to discuss what retaliation should look like in the event Trump follows through on his promise.

Ontario Premier Doug Ford and Prime Minister Justin Trudeau respond to Alberta Premier Danielle Smith declining to sign a joint statement by the premiers about Canada's response to Donald Trump's tariff threat.
