Ontario RCMP dismantles large-scale synthetic drug lab and seize nearly $10 million in product

The Ontario RCMP, with the help of several partners, have successfully dismantled a large-scale synthetic drug lab in Schomberg, Ontario. The investigation, which spanned several months, led to the seizure of nearly 10 million dollars worth of dangerous drugs and controlled substances, $8,000 in cash, prohibited weapons, and various types of chemical precursors capable of producing many more millions of dollars’ worth of illicit drugs.

The investigation was initiated in the spring of 2025 after the RCMP discovered a suspicious order of chemicals, placed by Christopher O’Quinn through his business, O’Quinn Industries. The chemicals ordered are known to police to be used in the production of fentanyl, MDMA, methamphetamine, and for cannabis extraction. In July 2025, specialized RCMP teams launched a further investigation into O’Quinn and two additional individuals suspected of manufacturing these illicit substances. The results of that investigation led the RCMP to discover that the three individuals were operating a large-scale drug lab at an address in Schomberg, Ontario.

On September 7, 2025, search warrants were executed, leading to the seizure nearly $10 million worth of suspected controlled substances, including MDMA, GHB, and methamphetamine. (Other synthetic opioids are still pending Health Canada testing). Approximately $8,000 in Canadian currency, along with an assortment of chemicals was recovered. In addition to cash, drugs and chemicals, officers discovered illegal equipment and materials including a pill press, firearms, various drug recipes, flasks and chemical glassware, and a variety of other lab components. Approximately 20,000 litres of hazardous waste were also removed from the site.

The complexity and danger of the drug production operation required RCMP, with the help of the Ontario Fire Marshal, Health Canada and King Fire and Emergency Services, ten days to safely dismantle.

As a result of the investigation, three individuals were arrested in connection with the drug operation, and are facing a total of 33 criminal charges:

Christopher O’Quinn is facing 20 charges related to drug production, trafficking, and weapons offences including:

• Production and trafficking of Schedule I substances including Methamphetamine, MDMA, and GHB
• Possession of chemicals and equipment intended for drug manufacturing
• Unlawful possession of prohibited firearms and devices, including a bullpup-style shotgun, .22 calibre rifle, and prohibited magazines
