Cocaine tops the list as the most confiscated substance in the southwestern region of Ontario along the Canada-U.S. border, according to data from both countries. Between January and June of this year, the Canada Border Services Agency (CBSA) seized more than 827,000 grams of cocaine, valued at over $82 million, at various border crossings including the Ambassador Bridge, Detroit-Windsor Tunnel, Blue Water Bridge, Peace Bridge, Queenston Bridge, Rainbow Bridge, and Walpole Island.
In the previous year, the CBSA seized 1,631,981 grams of cocaine, and in 2024, the amount confiscated was 1,515,369 grams, each year exceeding $150 million in value. Justin Morgan, the chief of operations at the CBSA for the Ambassador Bridge, stated that the majority of narcotics intercepted are coming from the United States.
Similarly, U.S. Customs and Border Protection (CBP) officials reported cocaine as the most seized substance at the same border crossings. In 2024, they confiscated 927,142 grams, and the figure increased to 2,092,875 grams in 2025. Notably, marijuana seizures by CBP this year have surpassed cocaine seizures significantly, with 1,797,133 grams of marijuana compared to 242,218 grams of cocaine seized between October 2025 and July 2026.
Benoît Gomis, a lecturer at the Munk School of Global Affairs and Public Policy in Toronto, pointed out that the data on drug seizures may not provide a comprehensive overview of the situation, leaving uncertainties about undetected border crossings. Gomis emphasized the complexity of interpreting drug seizure trends, suggesting they could be influenced by various factors such as chance, enforcement priorities, or actual changes in drug circulation.
The appeal of cocaine to criminal networks lies in its stable source primarily from Colombia and Peru, making it an attractive commodity for smuggling due to its compact nature. Gomis highlighted an increasing trend in cocaine consumption and purity, leading to heightened risks associated with the drug, including adulteration with substances like fentanyl.
The United Nations Office on Drugs and Crime has recognized global drug trafficking as a significant threat, particularly noting the impact of cocaine abuse in Canada. The latest data indicates that cocaine trafficking routes originate in South America, passing through Mexico into the U.S. and Canada.
To combat drug smuggling, the CBSA employs various detection methods at the U.S. border, including intelligence gathering, automated inspections, and the use of advanced technologies like detector dogs, X-ray equipment, and handheld devices. The new Gordie Howe International Bridge features enhanced detection capabilities, including X-ray technology for efficient commercial truck examinations, as well as specialized facilities for inspecting hazardous substances.
Overall, the ongoing battle against drug trafficking underscores the challenges faced by border enforcement agencies in intercepting illicit substances and safeguarding communities from the harmful effects of drug abuse.
