Five police services, supported by the Department of National Defence, teamed up to eradicate outdoor marijuana grows across southwestern Ontario between 14 and 18 September 2009 in an initiative dubbed Project OSABOT.[1] The Marihuana Eradication Team brought together officers from the Brantford Police Service, the Hamilton Police Service, the Niagara Regional Police, the Ontario Provincial Police and the Royal Canadian Mounted Police.[1]

The team targeted outdoor grows throughout the Hamilton and Niagara regions and Brant, Norfolk and Haldimand counties.[1] About 4,700 marijuana plants were seized and destroyed over the five days, with an estimated value of close to 4.7 million dollars.[1] Police said pooling information, people and equipment made the seizures larger and more cost-effective, and that similar teams had run earlier phases out of Kitchener, Kingston and London.[1]
