Marijuana Grow Operations


The Law Enforcement and Forfeited Property Management Statute Law Amendment Act, 2005, formerly Bill 128, was designed to help combat the threat to community safety posed by illegal marijuana grow operations ( MGO's).


  • The Municipal Act, 2001also requires that a local municipality ensure a building is inspected if notified by police or other authorities that a building housed a marijuana grow operation.
  • Marijuana grow – op bylaws differ throughout municipalities in Ontario.

Activities associated with Marijuana Grow Operations (MGO's) produce favorable conditions for mould growth and fungal amplification. The use of pesticides and fertilizers may also result in unsafe conditions. In order to protect unsuspecting homebuyers, investors as well as the public at large from these properties, CMTL has trained field and technical staff to help identify these hazards. Several municipalities have introduced "Grow-Op Bylaws" requiring that an Environmental Assessment be conducted to ensure a property is safe for occupancy when this activity has been discovered. If a property has been impacted by illegal activities, CMTL provides the following services:


  • Detailed initial inspection before/after any corrective action is completed, to ensure ESA compliance.
