If you apply pesticides commercially and you are not a technician or trainee, you need a Pesticide Exterminator licence from the Ministry of the Environment, Conservation and Parks (MECP) which authorizes you to apply pesticides according to your licence. All new exterminators are required to successfully complete a certification exam prior to obtaining the exterminator licence from the MECP.
Online exams will be facilitated by Open Learning at the University of Guelph. Please complete your registration if online exam delivery is preferred.
You must register and pay with OPT & C before you can sign up for your online exam.
- You must provide a valid email address
- You must be 16 years old or older to become certified
