Clad in protective gear and armed, Tim Thayer operates a U.S. Customs and Border Protection boat on the Detroit River with powerful engines. Thayer is part of a team monitoring the Canada-U.S. border in the region. The Detroit sector, covering Michigan, Ohio, Indiana, and Illinois, faces the unique challenge of a water border spanning 1,388 kilometers.

The proximity of Windsor, Ont., south of Detroit, connected by bridges and a tunnel, witnesses millions crossing annually. Thayer surveils the Windsor shoreline for suspicious activities during enforcement patrols, focusing on detecting people, narcotics, and firearms moving between the two countries.

In the past, the Windsor-Detroit corridor was popular for smuggling alcohol during Prohibition. Today, while illegal activities have decreased, the presence of recreational boaters poses a monitoring challenge for law enforcement. Intelligence and partnerships are crucial to securing the area effectively.

Recent data shows that the flow of illegal drugs and weapons is mainly northward from the U.S. into Canada. However, the U.S. has also experienced gun trafficking northward. Despite ongoing tensions, U.S. border officials emphasize the importance of partnerships with Canadian agencies for effective border security operations.

The relationship between the U.S. and Canada remains intact at the operational level, despite political differences. As Thayer observes an RCMP boat passing by, the Gordie Howe bridge symbolizes the complex dynamics between the two nations.
