A group of Canadian premiers and northeastern governors plan to convene in Boston June 16 to discuss the impacts of President Donald Trump’s tariffs on the United States and its neighbor to the north, according to Gov. Maura Healey’s office.

Healey’s office pitched the meeting earlier this month as a way for governors who oversee states that rely on trade with Canada to maintain “open lines of communication and cooperation” to overcome potentially negative impacts of the tariffs.

In a letter last month from Healey and five other state executives, the governors said businesses on both sides of the border “are already facing severe consequences from the trade war as the tariffs make life increasingly more expensive for our people and our businesses.”

“As we continue to navigate this period of great uncertainty, we are committed to preserving cross-border travel, encouraging tourism in our respective jurisdictions, amenities,” the governors said in the letter.

The letter was signed by Healey, Connecticut Gov. Ned Lamont, Maine Gov. Janet Mills, New York Gov. Kathy Hochul, Rhode Island Gov. Dan McKee, and Vermont Gov. Phil Scott. All of the governors are Democrats except Scott, who is a Republican.

The invitation was extended to the premiers of six Canadian provinces — New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, and Québec.

Healey’s office said details of the June meeting would be released prior to the event.

Trump has said he wants to make Canada the 51st state of the United States and has placed tariffs on exports from the long-standing ally.
