Chatham-Kent police raided a large commercial greenhouse on Maynard Line east of Chatham on 16 September 2020, seizing cannabis police valued at more than $7.3 million.[1] Officers took three days to dismantle the greenhouse, taking hundreds of plants.[1] A later police statement put the seizure at 7,300 plants and said a 48-year-old London man was charged with cultivating marijuana for the purpose of selling.[2]

At the time of the first report the investigation was still open and charges were pending.[1] Police said criminal organisations from outside the area rent vacant buildings in Chatham-Kent to hide large grow operations, with profits funding other organised crime.[2]
