There are some trade wars where the enemy is obvious. Canada isn’t one of them.
That is the message Michigan Democratic Rep. Debbie Dingell has been delivering with increasing urgency as President Donald Trump’s latest confrontation with Canada threatens to turn one of the world’s most integrated economic relationships into a very expensive game of chicken.
And Dingell isn’t exactly your stereotypical politician complaining about tariffs. She spent three decades working for General Motors. She represents Michigan, where the U.S. auto industry and Canada are so intertwined that an automobile can cross the border multiple times before it ever reaches a showroom.
Her basic argument is remarkably simple: Tariffs may be a tool. But using a sledgehammer to fix a watch isn’t exactly strategic policy.
Dingell has repeatedly warned that Trump’s escalating trade fight with Canada could hurt American workers and businesses as well as Canadians. In an August 25 statement, she said the two countries are “intertwined” economically and warned that a prolonged trade war would hurt working people on both sides of the border.
And then came the numbers. On CNN this weekend, Dingell put some real-world numbers behind her concerns.
Michigan exported $23.2 billion in goods to Canada in 2025, making Canada by far the state’s largest trading partner. She said more than 500,000 U.S. jobs are tied to auto parts used in vehicles manufactured in Canada, while more than 1.2 million American auto-industry jobs are connected to Canada.
That’s because the North American auto industry isn’t really three separate industries anymore. It’s one enormous supply chain. A part might be manufactured in Michigan, shipped to Canada, installed in a vehicle, sent back to the United States and then shipped somewhere else. Dingell said an auto part can cross the border eight times during the manufacturing process.
So, when Trump slaps a tariff on that Canadian component, the economic equivalent isn’t simply “Canada pays.” American companies pay. American workers pay. American consumers eventually pay. And then everyone gets to congratulate themselves for winning a trade war.
And Then There Are Cars
Trump’s latest escalation includes a proposed 50% tariff on Canadian-built vehicles and auto parts beginning January 1, 2027. That’s particularly troublesome for companies that depend heavily on Canadian production, including Ford, GM, Toyota and Honda.
Reuters reports that Canadian-built vehicles represented about 6% of U.S. auto sales in 2025, while the tariffs could significantly increase production costs and disrupt the North American supply chain. Toyota and Honda, which produce a large share of their Canadian vehicles there, could be especially exposed. Ford has another problem.
The company has invested billions in Canada, including a $3 billion investment in its Ontario operation, where it plans to build Super Duty pickups. Trump’s tariff policy now puts that investment squarely in the crosshairs.
Nothing says “America First” quite like making an American company’s Canadian factory substantially more expensive to supply the American market.
Dingell Isn’t Anti-Tariff
This is an important distinction—and one Dingell herself makes. She doesn’t argue that tariffs are inherently bad. In fact, she has said tariffs can be a legitimate “tool in the toolbox,” particularly when dealing with China.
Her objection is to using them indiscriminately against Canada. That’s a considerably different argument from simply shouting “Tariffs bad!”
And it comes from someone who knows the auto industry from the inside. Dingell has argued that the United States should pursue stronger trade policy, bring manufacturing home and reduce dependence on China—but do it strategically rather than disrupting the supply chains that American manufacturers already depend upon.
That’s where Trump’s policy begins to look less like an economic strategy and more like throwing a wrench into a machine and then blaming the machine for making noise.
Canada Is Not Exactly a Stranger
Canada supplies the United States with enormous quantities of energy and critical materials, including oil, aluminum and potash used by American agriculture. The two countries conducted roughly $872 billion in trade last year. Canada also supplied nearly 20% of U.S. petroleum consumption through its crude-oil exports.
This isn’t some distant country that happens to sell us maple syrup. Canada is America’s neighbor, major energy supplier, manufacturing partner, customer and ally. And Michigan knows that better than most.
Dingell has pointed out that people in parts of her district can literally look across the water and see Canada. In one interview, she described the relationship as economic security and national security. That makes Trump’s increasingly personal confrontation with Canada all the more difficult to understand.
When the Trade War Becomes Personal
The trade dispute has now gone well beyond tariffs. Trump recently signed an executive order attempting to rename Lake Ontario “Lake America.” Dingell responded that the Great Lakes are a shared treasure and said, in effect, that Trump can sign whatever paperwork he wants—people in Michigan and Canada are still going to call it Lake Ontario. She is also preparing legislation called the “Hands Off Our Great Lakes Act” to challenge the name change.
At some point, you have to wonder whether we’re negotiating a trade agreement or having the world’s most expensive neighborhood feud.
“You owe us money.”
“No, you owe us money.”
“Fine. I’m renaming your lake.”
At this rate, the next round of negotiations may involve crayons.
The Bill Eventually Comes Due
Trump’s argument is that tariffs will encourage companies to manufacture more in America. There is a legitimate policy debate to be had about protecting American manufacturing. But tariffs don’t magically eliminate supply chains, foreign inputs or higher production costs. They simply change who gets the bill.
And when the supplier, manufacturer and customer are all connected across the same border, the bill has a funny habit of finding its way back home. That’s Dingell’s point.
Canada doesn’t exist in some economic vacuum on the other side of a line on a map.
Neither does Michigan. Neither does Ford. Neither does GM.
Neither does the American consumer standing at a dealership wondering why the price of a pickup just went up again. Dingell has called for both countries to return to the negotiating table and reach a comprehensive agreement, warning that a prolonged trade war will hurt workers on both sides. That’s hardly radical.
It’s economics.
And perhaps the most ironic thing about Trump’s Canada strategy is that he keeps talking about making America stronger while picking a fight with one of the countries most deeply woven into the American economy.
You don’t strengthen the house by setting fire to the shared wall.
