Cocaine stands out as the most confiscated substance in the southwestern region of Ontario along the shared border of Canada and the United States, as revealed by data from both nations. From January to June this year, the Canada Border Services Agency (CBSA) intercepted over 827,000 grams of cocaine, valued at more than $82 million, at various key 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, followed by 1,515,369 grams in 2024, each with a value exceeding $150 million. Justin Morgan, the chief of operations at the Ambassador Bridge for the CBSA, highlighted that a significant portion of the narcotics originates from the United States.
Moreover, U.S. Customs and Border Protection (CBP) reported that cocaine was the most intercepted substance at the same border crossings. The CBP seized 927,142 grams in 2024 and 2,092,875 grams in 2025. According to a CBP watch commander, Lavarah Miller, a substantial amount of the intercepted substances heading towards Canada pass through Detroit from the U.S., rather than originating within Canada.
In the current year, marijuana interceptions by CBP (1,797,133 grams) have notably surpassed cocaine seizures (242,218 grams) at the border, covering the timeframe from October 1, 2025, to July 6, 2026.
Benoît Gomis, a lecturer at the Munk School of Global Affairs and Public Policy in Toronto, pointed out that the data on illegal substance seizures by law enforcement agencies may not provide a comprehensive view. Gomis emphasized the challenges in understanding the full extent of undetected border crossings. He explained that trends in drug seizures lack context and could result from varied factors such as fortunate large-scale interceptions, increased political efforts against specific substances, or a surge in drug circulation.
The allure of cocaine to criminal networks lies in its consistent supply source, primarily from Colombia and Peru, as noted by Gomis. The drug’s ease of smuggling due to its compact nature, established distribution networks, and steady demand further contribute to its appeal among criminal groups. Gomis also highlighted an apparent rise in cocaine consumption, with an estimated two to three percent of adults reported to have used the drug within the past year. He warned about increasing drug purity, potential lethality, and contamination with other substances like fentanyl, posing significant public health risks.
The United Nations Office on Drugs and Crime has flagged global drug trafficking as a substantial menace, particularly emphasizing the impact of cocaine in Canada. Notably, the data from 2020-23 showcased the trafficking routes originating in the Andean countries of South America, transiting through Mexico into the U.S., and extending into Canada.
The CBSA showcased its drug detection methods at the Ambassador Bridge port of entry, where intelligence-driven inspections and advanced technologies such as detector dogs, imaging units, and X-ray devices aid in uncovering illicit substances. The newly opened Gordie Howe International Bridge features cutting-edge detection technology, including X-ray capabilities for efficient commercial truck examinations, enhancing border security measures. Additionally, specialized examination facilities are equipped to handle hazardous substances like fentanyl and methamphetamine, ensuring thorough inspections and safeguarding against dangerous contraband.
