Vendor Certification

There are three types of pesticide vendor licences in Ontario -- General, Limited and Treated Seed.

General Vendor Licence

General Vendors may sell Class 1, 2, 3, 4, 5, 6 or 7 pesticides.  A business with a General Vendor Licence must have at least one full-time person on staff at the business outlet who is certified, that is, an employee who has successfully completed the Pesticide Vendor Certification Course.  

A Certified Vendor (named as Outlet Representative in the legislation) must:

  • be employed at the business outlet on a full-time basis or the owner, partner or officer/director of the business outlet;
  • be at least 16 years of age; and
  • have successfully completed the Pesticide Vendor Certification Course.

Note:  Once someone at your business is a Certified Vendor, you must apply to the Ministry of the Environment and Climate Change for a General Vendor's Licence for your business outlet.  When you apply, you will need to name the employees who are Certified Vendors at your place of business.  Application Form for a Vendor License for Pesticide Sales.

Limited Vendor Licence

The University of Guelph is committed to making its learning, living and work environments accessible and welcoming. In 2005, the province introduced the Accessibility for Ontarians with Disabilities Act (AODA), which seeks to ensure a fully accessible Ontario by 2025. This law moves from the concept of accommodation, where we make alterations on a per-person basis depending on that person’s disability, to one of accessibility where process, procedures, and policies are designed to improve access to the University’s people, goods and services.
