The Porous Divide: Deconstructing the Rhetoric of the Detroit-Windsor Border

While political leaders frame border security through the lens of national emergencies and tariffs, operational data from the Detroit sector reveals a complex, bidirectional flow of illicit goods and people.
As first reported by CBC News, the political theater of North American diplomacy often depicts the border as a unidirectional sieve. U.S. President Donald Trump has frequently characterized the Canadian border as a primary conduit for human traffickers and illegal drugs—specifically fentanyl—using these claims to justify aggressive economic measures. However, operational realities in the Detroit-Windsor corridor suggest that the systemic failures of border security are far more nuanced.
The geography of the Detroit sector presents a unique security challenge. The border in this region, which encompasses Michigan, Ohio, Indiana, and Illinois, consists of 1,388 kilometers of water. The proximity of Windsor, Ont., to Detroit—connected by a tunnel and two bridges—facilitates the annual movement of approximately seven million people. Kris Grogan, the chief of external communications at U.S. Customs and Border Protection (CBP) air and marine operations, noted that the sheer number of recreational boaters necessitates a reliance on partnerships and intelligence to secure the area.

**Opinion: The Cost of Political Framing**
*The insistence on framing border security as a failure of the neighboring sovereign state ignores the systemic reality: illicit flows are bidirectional. When political leaders use the border as a lever for tariffs, they risk obscuring the actual movement of threats. The data suggests that the 'danger' is not a failure of Canadian policy alone, but a symptom of a regional ecosystem where weapons and narcotics move fluidly across borders to meet demand on both sides.*

President Trump's assertions regarding the northern border led to the declaration of a national emergency in 2025. Under the International Emergency Economic Powers Act (IEEPA) of 1977, the U.S. administration levied 25 per cent tariffs on various Canadian goods. While the U.S. Supreme Court struck down these tariffs in February 2026, Ottawa has since committed approximately $1.3 billion in multi-year investments to enhance border security.
CBP statistics from the Detroit sector further complicate the political narrative. In 2025, border officials seized nearly 15 kilograms of fentanyl as part of a larger haul of more than 4,200 kilograms of illegal drugs. Lavarah Miller, a CBP watch commander at the new American port of entry facility at the Gordie Howe International Bridge, told CBC News that inbound drug smuggling is "not that big of a problem," noting instead that a significant amount of seized material is actually "going out" of the U.S.
This bidirectional flow extends to weaponry. Data compiled by the Ontario Provincial Police indicates that in 2024, 87 per cent of guns recovered in crimes within Ontario were traced back to the United States. Similarly, police in Toronto report that 88 per cent of recovered firearms were illegally smuggled into Canada.
Kelly Sundberg, a professor of criminology at Mount Royal University in Calgary, suggests that the U.S. serves as a critical "middle ground" for narcotics originating in South America and Mexico before they move north into Canada. While Sundberg acknowledges that Canada still poses a threat to the U.S., she clarifies that it is not the specific threat described by President Trump.
On the water, the challenges are equally persistent. Tim Thayer, a marine interdiction agent with CBP in the Detroit sector, observes that enforcement patrols consistently encounter a mix of people, narcotics, and guns moving in both directions. The Detroit-Windsor corridor, once the epicenter of Prohibition-era alcohol smuggling in the 1920s and '30s, remains a focal point for modern contraband.
