​

More than a month after the raid on a property on 20 Sideroad New Tecumseth (Schomberg by mailing address) the Ontario RCMP announced this morning it dismantled a large-scale synthetic drug lab whose investigation was started by a "suspicious purchase of chemicals."

​

At a press conference in Newmarket, RCMP said the investigation, spanned several months, led to the seizure of nearly $10 million 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.

​

Three people were arrested, two at the 20 Sideroad site and one in Port Colborne.

​

"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, 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 (New Tecumseth) 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, (New Tecumseth Fire Rescue also assisted) ten days to safely dismantle."
