Officers from the Ontario Provincial Police Organized Crime Enforcement Bureau and the Tyendinaga Police Service, with other police branches and Canada Border Services, executed search warrants on 23 and 24 September 2025 at four illicit cannabis production sites on Tyendinaga Mohawk Territory.[1][2]

Police seized more than 72,000 illicit cannabis plants with an estimated value above $122 million, plus three firearms, ammunition and other items.[1][2] Officers also stopped an unlawful diversion of water from the Bay of Quinte to the sites and seized offence-related property valued at about $530,000.[2]

Ten people, six of them not members of Tyendinaga Mohawk Territory, were arrested and charged under the Criminal Code and the Cannabis Act.[1][2] They were released and ordered to appear before the Ontario Court of Justice in Belleville on 5 November 2025.[2] Police said the sites were controlled by non-Indigenous organized criminal networks aided by a limited number of community members, after an investigation begun in April 2025.[1][2]
