Prime Minister Mark Carney and President Donald Trump have maintained regular contact through phone calls on trade, NATO, Iran, and other issues, even as formal bilateral meetings have been limited amid stalled CUSMA renewal talks and reciprocal tariffs. Carney, who has met Trump in person at the White House and engaged informally at the G7, arrived in New York for the UN General Assembly in late September 2026 without a scheduled bilateral, though schedules can shift. Ongoing diplomatic frictions over tariffs and investment flows, alongside Carney’s outreach to European and other partners, shape expectations around the timing of any next in-person encounter. Traders weigh these dynamics against historical patterns of U.S.-Canada leader interactions during periods of trade tension.
