Cross-Border Relations Strain as Tariffs Impact Sault Ste. Marie

In late June, almost 1,100 individuals took part in the International Bridge Walk at Michigan’s Upper Peninsula. This annual event highlights the connection between two cities bearing the same name: Sault Ste. Marie in Michigan and Sault Ste. Marie in Ontario. Under the bright sun, participants embraced a spirit of unity. Don Gerrie, the mayor of the Michigan Sault, emphasized this by addressing the crowd. “We don’t like to say there’s a border there,” he said. “We’re twin cities, one family, both countries of Canada and the United States.” Wearing a cap from his Ontario counterpart featuring flags and the slogans “Stronger Together” and “Allies and Friends,” the mayor symbolized the friendly bond shared across the border.

Participants in the walk embodied a vivid display of patriotism. Canadians donned maple leaf-themed clothing, while Americans sported star-spangled attire. Despite the lively atmosphere, tension between the U.S. and Canada has increased, casting a shadow on this tradition.

Decline in Bridge Traffic

Bridge traffic has decreased significantly. Recent moves by President Donald Trump have played a role in straining relations. He proposed new tariffs in response to smoke from Canadian wildfires affecting the U.S. An additional 50% tariff, alongside a further 10% tariff, was imposed on Canadian products. The White House mentioned “Canada’s discriminatory treatment of American products” as justification.

A new bridge, the Gordie Howe International Bridge, opened between Detroit and Windsor. However, Trump did not attend the inauguration as Canada held a ceremony exclusive to Canadian officials. The absence of local congressional representatives at the bridge walk amplified the delicate relationship. Rep. Jack Bergman, a Republican endorsed by Trump for an upcoming primary, remained silent on the tariff impacts, although he previously praised ties with Canada.

Economic Impact

The reduction in cross-border activity has economic consequences. The International Bridge Administration reported a $82.9 million loss last year in local expenditure due to less traffic: $62.7 million on the Michigan side and $20.2 million on the Ontario side. There were 270,000 fewer crossings, a nearly 24% decrease compared to 2024. Canadian travelers account for much of this decline.

According to the bridge director, auto traffic remains low and commercial crossings have fallen by nearly 15%. Nationwide, fewer Canadians are visiting the U.S. Michael Broadway, a retired geographer at Northern Michigan University, attributed this to a boycott of the U.S. He commented that while federal policy is beyond individual control, Canadians are choosing to express dissent through travel choices.

Challenges and Responses

The Sault bridge is essential for commerce and stands as the only vehicular border crossing for several hundred miles. Decreased traffic is threatening the economy of Michigan’s Upper Peninsula. The bridge, reliant on toll revenues, faces financial challenges. A five-year plan from the bridge authority highlights how reduced traffic and trade could strain operational sustainability.

Local businesses, especially during off-seasons, are experiencing decreased Canadian patronage. Wilda Hopper from Bird’s Eye Outfitters notes a 27% business reduction. Michigan state Sen. John Damoose acknowledges the pressure on Mackinac Island and the broader region due to deteriorating U.S.-Canada relations. He recalls historic instances of cross-border collaboration, such as Canadians assisting Michigan after a harsh ice storm.

Politically, Michigan’s Democratic Senators, Gary Peters and Elissa Slotkin, challenge Trump’s tariffs, characterizing them as “chaotic” and “sloppy,” and highlighting Congress’s role in tariff implementation. They seek measures for greater tariff transparency.

Trump’s second term displays a shift in trade perspectives that pose difficulties for Michigan’s agricultural sector, the state’s second-largest industry. A yet-to-be-released state report indicates a 12.3% drop in exports to Canada last year, emphasizing strain on the U.S.’s most important trade partner.

The U.S.-Canada relationship continues to worsen. A White House document notes changing Canadian business practices, including a 22% decrease in vehicle imports from the U.S. Mark Carney, Canada’s Prime Minister, condemns the U.S. tariffs as violations of a North American trade agreement initially celebrated by Trump. As this pact’s renewal approaches, the U.S. administration has declined to extend the agreement long-term. Carney remarks that Canada’s strong ties to the U.S. have morphed into vulnerabilities that need correction, pointing to a pursuit of diverse international partnerships.

Future Outlook

The Sault Ste. Marie International Bridge remains a vital link in North America. Situated over the St. Mary’s River and near the Soo Locks, it connects the world’s two largest economies. Recent policies challenge the unity once celebrated in events like the International Bridge Walk. How the twin Sault Ste. Maries navigate the economic and political landscape will influence future cross-border relations.
