Pesticide classification guideline
This Pesticide Classification Guideline for Ontario provides details on the classification system set out in sections 3 to 8 of the Regulation. These sections outline the decision-making framework for classifying pesticides and describe the eleven classes of pesticides.
Class lists
Under Section 4(1) of Regulation 63/09 under the Pesticides Act the Director has the authority to add or remove pesticides to maintain an updated list. As such, the number and names of pesticides on these lists will change generally on a monthly basis as newly registered pesticides are classified for sale and use in Ontario, or as products are reclassified or declassified. Please note the date on which the individual class lists have been updated.
