Tensions and Cooperation on the Detroit-Windsor Waterway

The Detroit River Patrol and Its Challenges
Marine interdiction agent Tim Thayer operates a 18,000-pound U.S. Customs and Border Protection (CBP) boat on the Detroit River, a segment of the 1,388-kilometre water border that separates Michigan, Ohio, Indiana and Illinois from Ontario. The corridor links the cities of Detroit and Windsor, where roughly seven million people cross each year via two bridges and a tunnel. The high volume of recreational traffic forces agents to treat every vessel as a potential smuggling platform.
Drug and Firearm Flows Across the Border
CBP statistics for 2025 show the Detroit sector seized more than 4,200 kilograms of illegal drugs, including nearly 15 kilograms of fentanyl. Guns travel northward in larger numbers: Ontario police traced 87 percent of firearms recovered in 2024 to the United States, and Toronto police reported 88 percent of seized guns originated south of the border.
Political Claims vs. Border Realities
In early 2025, President Donald Trump declared a national emergency at the northern border, citing fentanyl and human-trafficking concerns, and imposed 25 percent tariffs on Canadian goods under the International Emergency Economic Powers Act. The U.S. Supreme Court later struck down those tariffs. CBP data contradicts the narrative of a fentanyl influx from Canada: in May, less than 0.5 kilogram was seized at the Canada-U.S. border, compared with 358 kilograms at the Mexico-U.S. border. Year-to-date totals show roughly 3 kilograms of fentanyl seized from Canada versus 3,221 kilograms from Mexico. Kevin Brosseau, Canada’s “fentanyl czar,” highlighted these disparities.
Official Cooperation Between Agencies
Tim Balkus, the patrol agent in charge of the Detroit sector, affirmed that “locally, we still have great partnerships with those agencies right across the water.” CBP’s air and marine operations rely on intelligence sharing and joint patrols with the Royal Canadian Mounted Police, a coordination underscored by the newly opened Gordie Howe International Bridge.
