OTTAWA — Canada’s premiers are set for two days of huddling in the nation’s capital with the economy, affordability and trade expected to be high on the agenda. The premiers meet with Prime Minister Mark Carney on Thursday, and will want to show a united “Team Canada” front as trade tensions rise again with Canada’s largest trading partner. The meetings come a year after U.S. President Donald Trump assumed office and hit Canada with blistering tariffs, and just ahead of negotiations to renew the Canada-United States-Mexico agreement, due for its first formal review this summer. Trump threatened Canada in recent days with 100% across-the-board tariffs on exports, which would land on top of the sectors already hit by steep U.S. tariffs, such as steel, softwood lumber and vehicles. Ontario Premier Doug Ford said the premiers will show they stand united as the whole Canadian economy remains under attack.
