Does pest control need a licence in Ontario, and how do you check?
Yes. Unless exempt, anyone who applies pesticides commercially on property they or their employer do not own needs a pesticide exterminator licence, valid for 5 years; indoor pest control falls under the Structural class, and termite work needs the separate Termite class. The business itself needs a pesticide operator licence, which expires each December 31, and operator licences issued since September 2018 can be searched on Ontario's Access Environment.[1],[2],[3]
How to check
Search Ontario's Access Environment for the company's pesticide operator licence: operator and vendor licences issued since September 2018 are listed there. To hold one, the business must be a licensed exterminator or employ licensed exterminators, and carry insurance.[3]
