WASHINGTON — The Canada–U.S. file used to be the boring excellence of North American government. On May 30, 2026 it was steel and aluminum duties, and nobody in the room called it boring. The scene at the Eisenhower Executive Office Building was the kind of Washington tableau that looks choreographed until you watch the aides check their phones. The an AI liability bill hiding inside steel and aluminum duties is the polite way to describe a capital that is fighting a war, an election and a trade rupture at the same time.
The nut of it is simple, and Canadians should not dress it up. American power still sets the tempo for North America, but it is being spent with less patience and more theatre. Steel and aluminum duties is where that impatience showed on May 30, 2026. The war with Iran was 80 days old, which in Washington is long enough for the first briefings to go stale and not long enough for anyone to describe an off-ramp with a straight face. Shipping through Hormuz had become a daily wager. A barrel of crude around US$92.4 did more to set the president’s mood than any prepared remark.
There is always a paper trail. Staffers circulated an AI liability bill with the serial number H.R. 2868, which is how Washington pretends a political choice is a technical one. In Armed Services, members asked questions they already knew the answers to, then left to tape hits that would be clipped before dinner. The public argument was about principle. The private argument was about 40 per cent of a slice of the map that still decides who runs the House.
"Steel and aluminum duties is not a messaging problem. It is a governing problem," a Midwestern governor’s chief of staff told Maclean’s. The conversation happened the way they happen now: off to the side, on background, with a glance at the door. "You can survive a bad clip. You cannot survive a month of prices that people feel in the driveway." In Savannah, that sentence would not be a metaphor.
The talks that were supposed to keep USMCA in the realm of technicians collapsed into a contest of tariffs. Fifty per cent is a political number, not an economic one — round, loud and easy to put on a hat. Ottawa’s answer, under Carney, has been to match rather than plead, and to tell Canadian firms to stop waiting for a mood swing in the Oval Office. That is a new tone in a very old relationship.
