How are pesticides classified under the Ontario regulation?

The classification of pesticides under Ontario regulation primarily follows the framework established by the Pesticides Control Products Act (PCPA). This act serves as the foundational legislation governing the use, sale, and registration of pesticides in Canada, including Ontario. It stipulates the criteria and processes for determining which substances qualify as pesticides, how they are regulated, and the standards they must meet for safety and efficacy before being made available for use.

The act plays a crucial role in ensuring that pesticides are scientifically assessed and categorized appropriately, taking into account factors such as their potential risks to human health and the environment. While other classifications, such as those based on environmental impact, toxicity level, or user type, may be considered in specific contexts or for particular regulatory purposes, the primary legal structure for pesticide classification in Ontario derives from the PCPA. This ensures consistent application of the law and provides guidance for pesticide users and manufacturers on compliance with regulations.
