As many of us know in the Southeast Michigan business community, the Windsor-Detroit corridor is more than just a border crossing – it’s one of North America’s most critical commercial lifelines. Every day, millions of dollars in goods and services, along with thousands of workers, cross the Detroit River, linking Canada’s manufacturing strength in Windsor with the industrial core of Michigan. This is not simply a regional connection; it’s a binational ecosystem that anchors the prosperity of two nations.
With the opening of the Gordie Howe International Bridge in 2026, another significant chapter in our long-standing international relationship will begin. Yet, for all its importance, few truly understand the intricate challenges of doing business across the border. Beneath the daily rhythm of commerce lies a complex web of legal, logistical, and economic factors that shape every decision made by companies dependent on cross-border trade.
With offices in both Southeast Michigan and Windsor, Dickinson Wright has worked alongside companies for decades to understand, navigate, and adapt to this ever-changing corridor that is the lifeblood of our economy and culture.
A Region Built on Interdependence
The Windsor–Detroit connection is as much about people as it is about products. Decades of collaboration between automakers, suppliers, and professional service providers have made this region an economic powerhouse.
“This interdependence creates both great opportunity and, at times, risk that needs skillfully managed. We excel at both.” says Michael C. Hammer, CEO of Dickinson Wright. “This cross-border mindset that we have developed over decades of experience when it comes to thinking about business is not just a concept; it’s in our DNA.”
A delay at the Ambassador Bridge, a new regulation in Washington or Ottawa, or a sudden shift in tariff policy can disrupt the finely tuned rhythm of production. Dickinson Wright’s multidisciplinary cross-border teams collaborate across offices and practices – including immigration, trade and customs, and regulatory compliance – to ensure businesses anticipate these complexities and reduce the risk for operational and financial disruption.
Beyond the Booth: A Maze of Regulations
Operating across the Windsor–Detroit corridor requires more than a passport — it requires a deep understanding of two distinct regulatory and legal systems, says John D. Leslie, Director of Cross Border Practices at Dickinson Wright. Differences in taxation, labor law, environmental compliance, and even professional licensing can complicate cross-border operations.
“These are not mere administrative burdens; they are strategic challenges that define success or failure in cross-border trade,” says John. “It’s why we closely monitor legislation on both sides of the border to advocate for our clients’ interests and assist them in understanding how new regulations impact their North American operations.”

Nowhere is this more important than in the current tariff policy environment. Tariffs on steel, aluminum, and automotive components — even when temporary — have an outsized impact on the Windsor–Detroit economy.
For cross-border companies, tariff literacy is not optional, says John. It requires monitoring shifting political landscapes, understanding preferential duty treatment, and structuring supply chains to mitigate exposure. In a region as integrated as Windsor–Detroit, where the same part might cross the border multiple times, even a modest tariff can compound into a significant financial burden.
A Shared Future
Understanding the Windsor–Detroit business corridor isn’t just about navigating checkpoints; it’s about mastering the art of international cooperation. In an era of trade realignment and policy uncertainty, this region stands as a model for what an adaptive, resilient cross-border economy can look like.
The Windsor–Detroit story is, ultimately, a North American story — one of connection, adaptation, and shared ambition. Those who understand its challenges will not only thrive within this corridor but will help define the next generation of cross-border commerce.
