President Trump spoke with Canadian Prime Minister Mark Carney on Friday for the first time since Carney was elected earlier in the month amid tensions between the two nations.

“It was an extremely productive call, we agree on many things, and will be meeting immediately after Canada’s upcoming Election to work on elements of Politics, Business, and all other factors, that will end up being great for both the United States of America and Canada,” Trump posted on Truth Social.

The conversation came a day after Carney, who replaced former Prime Minister Justin Trudeau, delivered a speech declaring the U.S. was “no longer a reliable partner.”

“It is possible that with comprehensive negotiations, we could reestablish an element of confidence, but there will be no going backwards,” Carney said.

Trump has for months taunted Canada by suggesting it should be annexed and join the United States as the 51st state, which Canadian leaders have rebuffed.

The president has also imposed sweeping tariffs on Canada, complaining about the trade imbalance between the two nations. That has prompted talk of retaliatory measures from Canada, raising the prospect of a broader trade war.

Trump earlier in the month imposed a 25 percent tariff on all imports from Canada, a move he later walked back with exemptions for goods covered by the U.S.-Mexico-Canada trade agreement signed in 2020.

Trump on Thursday had warned Canada and the European Union against working to do “economic harm” to the U.S. in response to the president’s widespread tariffs.
