Certified Farmers

Farmers must be certifed to buy and use Class 2 or 3 pesticides on their farms or woodlots, or on the farm that they work on.  To become certified, a farmer must complete the Grower Pesticide Safety Course.  We offer online and in-person courses

New - staring January 1, 2021  There are some agricultural pesticides that farmers are currently allowed to buy and use without certification, called Class 4.  Staring Jan. 1, 2021, farmers need to be certificd to buy and use these pesticides.  

On-Farm Instructors

In Ontario, farmers who mix, load or apply Class 2 or 3 pesticides under supervision of a Certified Farmer must be trained. Class 4 agricultural pesticides will also be included starting on January 1, 2021.  Supervised farmers are called Farmer Assistants.  There are two ways for Farmer Assistants to participate in training. They can:

  1. participate in a Grower Pesticide Safety Course or
  2. participate in a Pesticide Safety for Farmer Assistants training session presented by an On-Farm Instructor.

Pesticide Vendors

Pesticide vendors need to be certified under the Pesticide Vendor Certification Course before applying for a General Vendor pesticide licence. In Ontario, pesticide vendors need a licence to sell or transfer pesticides. There are three types of pesticide vendor licences: General Vendor, Limited Vendor, and Treated Seed Vendor. Each separate business location needs its own vendor licence.
