Trump is waging economic war on Canada and calling it trade policy.

Now, I’m just a simple man, but when a nation’s largest trading partner holds a ribbon-cutting ceremony for a bridge that took years to build and tells the Americans to stay home, you’re not in a trade dispute anymore. You’re in a crisis. The Gordie Howe International Bridge opens to traffic on Monday, a multibillion‑dollar span that took decades of political heavy lifting and engineering muscle to connect Detroit and Windsor. The United States was supposed to be there. The invitation got pulled after the White House dropped a 50‑percent tariff on everything Canada sells us, and Canada decided it didn’t need a photo op with the people who just slapped a punishment on its entire economy.

That decision, as my late father used to say about a customer who brought his truck back three times for the same problem, has a name and a consequence. The name is the Trump administration. The consequence is that we are now treating the country that buys more from us than anyone else like it’s a foreign adversary, not a neighbor. More than 70 percent of Canada’s exports come to the United States, and Detroit is the busiest port for truck traffic on the border. That trade keeps assembly lines running in Michigan, puts diesel in the tanks of truckers who haul auto parts from Windsor to Ohio, and pays the wages of the working people who, for all the political talk, are the ones who are going to feel this first.

I’ve spent enough years running an auto shop to know what happens when you try to squeeze your best supplier. Zebedee Auto has been in business for two generations because my dad and I understood that a reliable parts distributor you can call at five o’clock on a Friday is worth more than a few percentage points you might save by shopping the competition. You don’t cancel the guy who keeps your bays full because you’re mad about something else. You certainly don’t uninvite him to the party and expect him to keep cutting you a deal.

The bridge itself is named for Gordie Howe — Mr. Hockey, No. 9 — a Canadian kid who crossed the Detroit River to become one of the greatest hockey players ever to wear a Red Wings sweater. The name is a reminder that the border up here isn’t a wall; it’s a seam. Families have lived on both sides for generations. The auto industry built its just‑in‑time supply chains right across it. The trucks that will roll over that bridge starting Monday morning carry brake calipers, injection molds, maple syrup, and a hundred other things that only make sense when you see the two economies as one organism that can’t be divided with a tariff rate.

And here’s the thing: every one of those trucks is now a moving piece of a relationship that the United States is actively destroying. I am not talking about some abstract “trade partnership” that economists argue about in journals. I am talking about the men and women who keep those trucks running. The dispatchers in Toledo and the customs brokers in Windsor. The waitresses at the truck-stop diners who know a regular’s order before he sits down. The 50‑percent tariff will make every load more expensive. Some loads will stop moving. Some jobs will disappear. That is not a negotiating tactic; it is an act of self‑sabotage dressed up in the language of strength.

I used to hear the argument, years ago, that America’s economic leverage came from being the biggest customer in the room, and that we should use it. That was before I read much, and before I started paying attention to what happens in a small town when the factory that depended on cross‑border parts closes its doors. The leverage argument is a cheat. It treats a trading relationship like a mugging — do what I say or I’ll stop buying from you — and it ignores the fact that the mugger is also the one who depends on the money that comes from the exchange. Canada buys hundreds of billions of dollars of American goods every year. If you were to walk into my shop and tell me you were going to fire your biggest customer to prove a point, I would tell you that you are about to lose your business and your reputation.

The White House, of course, will frame this as standing up for American workers. I have no doubt the press releases are being written right now with the usual words — tough, fair, reciprocal. What they will not say is that the American workers who live along the Detroit‑Windsor corridor, and the ones in every state that moves goods across the northern border, are the ones who will pay the price. The same administration that preaches loyalty to the working class just made an entire class of working people the collateral damage in a fight with a country that has been our ally for over a century. That is not strength. It is what happens when the political class treats the economy like a game show where only the final score matters, and the contestants are not in the studio audience.

At a certain point, you have to step back and look at the map. The United States shares a continent with Canada and Mexico. We have the good fortune of being anchored between two enormous trading partners who don’t require us to station a single aircraft carrier to keep trade routes open. The last century taught us that secure borders and friendly neighbors are strategic assets that money can’t buy. To treat that inheritance as a chip to be thrown on the table in a tariff fight is a mistake so big that even the quietest American will eventually have to reckon with it. The Eisenhower in me would call it a betrayal of the long‑view thinking that has always been the real source of American power.

The bridge will open on Monday, and traffic will cross. That is because Canadians, whatever they think of this administration’s choices, still believe that keeping goods moving is better than letting them sit at the dock. The American side will be open too, because we still have customs agents who know how to process a manifest. But the ceremony that should have marked this as a moment of common purpose was held without us. The invitations were withdrawn, not because the bridge isn’t a shared accomplishment, but because one side decided it would rather stage a tantrum than accept a handshake.

I do not think most Americans want this. I think most Americans, the ones who are not watching the cable shows or reading the partisan press releases, know that good neighbors don’t act like this. They know that when a family across the street builds a new driveway that connects to yours, you don’t call the cops on them the day they invite you over. You bring a pie. You ask about their kids. You remember that the road you share is the one you are going to drive on tomorrow, and the day after, and the day after that.

The cold ledger, the part that does not care about ceremony or pride, is this: we have a president who has chosen to make Canada an economic enemy while the trucks are still idling at the border. The bridge will open, but the invitation is gone. And a lot of working people on both sides of that river are going to find out that losing a partner costs more than any tariff can bring in.
