Ontario Premier Doug Ford says Prime Minister Mark Carney has agreed to a first ministers meeting following U.S. President Donald Trump’s latest tariff threat.

Prime Minister Mark Carney will be meeting with his cabinet and Canada's premiers to discuss U.S. President Donald Trump's new threat to slap 35 per cent tariffs on Canadian goods next month.

The letter reiterated Trump’s complaints about dairy quotas, fentanyl and the U.S. trade deficit, which is mostly fueled by American refineries’ thirst for Canadian oil. His social media post caused the Canadian dollar to immediately tumble, indicating the market wasn’t expecting this escalation.
