Notification of Marijuana Grow Operation Protocol

Agreement Between Police Services and Municipalities

Read the legislative requirements related to the Protocol.

Statement of principle

Marijuana grow operations (MGOs) pose a serious threat to the safety and security of municipalities throughout Ontario. The detection, investigation, dismantling, and return of premises to legitimate use is a complex undertaking requiring the cooperation of police and municipal officials. A coordinated approach to this problem will help ensure that the entire process is conducted in a safe and effective manner. The safety of the personnel involved in the process and that of the public is of paramount importance.


The purpose of this protocol is to assist the police service and municipality to provide an effective and coordinated response when dealing with premises that have operated as a marijuana grow operation. This response will help to ensure that, once police identify a property as a marijuana grow operation, necessary steps are taken to have the building made safe for the public.

For the purposes of this protocol, municipality means a single-tier municipal government or an upper-tier and one or more lower-tier municipal governments.
