The premiers will be gathering in Ontario cottage country this week for a meeting focused on Canada’s continuing response to President Donald Trump’s tariff threats, and an update from Mark Carney on the state of trade and security negotiations with the U.S.

It will be the first sit down between the Prime Minister and provincial and territorial leaders since Mr. Trump threatened to impose 35-per-cent tariffs on Canadian goods outside the United States-Mexico-Canada Agreement, which are currently subjected to 25-per-cent tariffs.

A landmark meeting between Mark Carney and First Nations leaders ended the way it began Thursday, with a divergence of views on display that signalled a long road ahead for the Prime Minister’s plan to fast-track major projects.

Some leaders emerged with a sense that Mr. Carney had listened thoughtfully to their points of view.

Prime Minister Mark Carney says securing a truce in the long-running Canada-U.S. softwood-lumber dispute is a top priority as Canadian producers brace for even heftier U.S. levies as early as September.

Mr. Carney said he hopes this could be part of an overall agreement to end the trade war with the United States – a deal he conceded earlier this week would likely not remove all of President Donald Trump’s tariffs from Canadian goods.
