Cocaine stands out as the most commonly confiscated substance in the southwestern Ontario region along the Canada-U.S. border, as per data from both nations. From January to June this year, the Canada Border Services Agency (CBSA) seized over 827,000 grams of cocaine, valued at more than $82 million, at various border points 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, with a similar amount seized in 2024, each valued at over $150 million.
Justin Morgan, the chief of operations at the Ambassador Bridge for the CBSA, mentioned that the majority of illicit narcotics come from the United States. U.S. Customs and Border Protection (CBP) data also revealed that cocaine was the predominant substance seized at these border crossings, with 927,142 grams seized in 2024 and 2,092,875 grams in 2025. Lavarah Miller, a Customs and Border Protection watch commander, noted that a substantial part of the seized substances en route to Canada from the U.S. rather than originating within Canada.
Contrary to expectations, marijuana seizures by the CBP have surpassed cocaine seizures this year, with 1,797,133 grams of marijuana seized compared to 242,218 grams of cocaine 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 seizure data may not provide a comprehensive overview of illegal substance trafficking. Gomis emphasized the uncertainty surrounding the quantity of undetected substances crossing the border.
Cocaine remains an attractive commodity for criminal networks due to its stable source primarily found in Colombia and Peru. Gomis highlighted the ease of smuggling cocaine due to its compact size and established distribution networks. Additionally, recent trends suggest an increase in cocaine consumption globally, with rising purity levels contributing to heightened health risks. The United Nations Office on Drugs and Crime has identified cocaine trafficking as a significant threat globally, emphasizing its detrimental impact on public health.
The CBSA utilizes various methods, including intelligence data and advanced detection technology like detector dogs and X-ray units, to intercept illicit substances at border crossings. The new Gordie Howe International Bridge features cutting-edge detection technology, such as X-ray capabilities, to streamline commercial truck inspections and enhance border security measures. Sydney Kale, CBSA’s district director for the Gordie Howe International Bridge, highlighted the specialized facilities available for inspecting packages containing hazardous substances like fentanyl and methamphetamine.
As Canada enhances its border security measures with advanced detection technologies, the fight against drug trafficking and smuggling continues to be a top priority for law enforcement agencies.
