SAULT STE. MARIE, Mich. — The International Bridge looms over this quiet border town, a daily reminder of the intricate ties that bind Michigan to its northern neighbor. But lately, that bridge has become a symbol of uncertainty. President Trump’s tariffs on Canadian steel and aluminum, and Ottawa’s retaliatory measures, have thrust this community into the center of an escalating trade war — and left local voters grappling with conflicting loyalties as the November midterms approach.

Michigan’s trade relationship with Canada is among the deepest of any U.S. state. Canada purchases more than $20 billion in Michigan goods annually, and the two economies are intertwined through automotive manufacturing, agriculture, and tourism. For border towns like Sault Ste. Marie, those cross-border flows are the lifeblood of the local economy.

A Bridge to Prosperity? The Economic Stakes

The tariffs, announced in early 2018, targeted Canadian steel and aluminum, citing national security grounds. Canada swiftly retaliated with its own tariffs on U.S. goods, ranging from ketchup to lawn mowers to steel. For Sault Ste. Marie, the effects are not abstract. The Soo Locks, a major shipping artery, handle iron ore and other bulk cargo, while the Sault Ste. Marie bridge carries truck traffic carrying everything from auto parts to maple syrup.

“We see the impact every day,” says Tom Hartley, president of the local Chamber of Commerce. “Businesses on both sides of the border are deferring investments, and consumers are feeling the pinch at the pump and the grocery store.” Hartley, who asked not to be quoted by name in order to remain politically neutral, added that the uncertainty is “rippling through our community.”

Retailers in downtown Sault Ste. Marie have noticed a dip in Canadian shoppers, who historically cross the border to take advantage of lower prices on gasoline, dairy, and apparel. The weak Canadian dollar, compounded by the tariff conflict, has made those trips less attractive.

Tariffs in Perspective: A Double-Edged Sword

Yet the issue is far from black and white. Some residents express support for the President’s tougher stance on trade, arguing that decades of outsourcing and alleged dumping have harmed American manufacturing.

“We need to bring good-paying jobs back. If that means short-term pain, so be it,” said Mike Kowalski, a steelworker from neighboring Sault Ste. Marie, Ontario, who commutes to a plant on the U.S. side. His voice reflects a broader sentiment that resonates with many union voters in the Midwest.

This ambivalence is precisely why the midterm politics here are so complicated. In 2016, many voters in Michigan’s Upper Peninsula backed Donald Trump, attracted by his promise to renegotiate trade agreements and revitalize manufacturing. But the reality of tariffs has complicated that narrative.

The Local Context: A Region Dependent on Cross-Border Trade

Sault Ste. Marie, Michigan (pop. 13,500), sits across the river from a comparably sized Canadian city. Together, they form a binational community where families, businesses, and municipal governments routinely collaborate. The local hospital treats Canadian patients; Canadian utilities supply electricity to Michigan homes; and many residents hold dual citizenship.

“This is not ‘them’ versus ‘us,’” notes Jane Reynolds, a trade policy expert at Michigan State University. “The economies are so integrated that any tariff is like a stone dropped into a shared pond. The ripples hit both sides.” Reynolds argues that the trade war undermines Michigan’s economic recovery, particularly in the automotive sector, which relies on cross-border supply chains that cross back and forth multiple times before a car is assembled.

The Auto Industry Connection

Automotive parts alone account for nearly a quarter of Michigan’s exports to Canada. With tariffs pushing up costs, automakers have warned of higher car prices and potential job losses. In the U.P., where many small suppliers feed into the industry, the risk is palpable.

• Michigan exports to Canada support roughly 190,000 jobs across the state.
• Approximately three-quarters of Michigan’s inbound cargo comes through border crossings like Sault Ste. Marie.
• The U.S. Chamber of Commerce has estimated that tariffs on steel and aluminum could cost Michigan 15,000 to 25,000 jobs if they spark a sustained trade war.

Midterm Calculus: Voters Feel the Squeeze

As the midterms approach, candidates are wrestling with how to address the tariffs. Democratic challengers in the region have seized on the economic anxiety, citing the trade war as evidence of the administration’s “America First” policy gone awry. Incumbent Republicans, meanwhile, often downplay the immediate pain, emphasizing the administration’s efforts to press Canada for a revised NAFTA agreement.

But for many voters here, the tariffs are not an abstraction. “I bought a new furnace, and it cost me $300 more because of steel tariffs,” says Susan Aldrich, a retired teacher who lives just outside town. “I want to support American jobs, but at some point, you have to ask who’s getting hurt.”

Polls suggest that trade is a top concern among Michigan voters, but it does not break neatly along party lines. A recent survey from the Michigan Ross School of Business found that 58% of likely voters in the state disapprove of the President’s handling of trade negotiations, while 42% approve. Yet those same voters split sharply when asked about Republicans versus Democrats in Congress.

The Political Tightrope

For candidates in the 1st Congressional District, which includes Sault Ste. Marie, the challenge is to navigate the nuances. The district is solidly Republican in state politics but has a history of populist leanings. “Candidates have to talk about trade in a way that respects the President’s goals but also acknowledges the local pain,” says political analyst Karen Delaney.

Looking Ahead: What It Means for November and Beyond

Experts caution that the full impact of the tariffs may not be felt until after the election, as business decisions and supply-chain shifts take time to materialize. But the uncertainty itself is corrosive. “Even if the tariffs are eventually lifted, the damage to trust could linger,” warns Reynolds. “Firms remember the risk, and foreign buyers may seek more reliable suppliers.”

In Sault Ste. Marie, residents are pragmatic. Many hope for a negotiated resolution before the winter, when the shipping season ends and the town becomes more isolated. Until then, the debate over tariffs remains a high-stakes balancing act — one where every bolt, beam, and imported product carries a political price tag.

On a blustery October afternoon at a local diner on Ashmun Street, the discussion among a group of retirees captured the mood. “I voted for him because he said he would shake things up,” said Bob Johnston, a retired trucker. “Maybe he is shaking things up, but I didn’t think it would shake my wallet.”

Across the counter, Jim Pearson, a farmer and staunch supporter of the President, demurred. “Trade wars are easy to lose if you cave. You gotta hold the line.” The two men ordered their coffees, their dispute unresolved — a small reflection of a nation divided, where the border town is more than just a crossing. It is a test case for how tariffs, and the politics behind them, will play out in the midterms and far beyond.
