Which of the following is NOT a class of pesticide products defined by the Pest Control Act?

The classification of pesticide products under the Pest Control Act is designed to ensure that different types of pesticides are properly regulated and that users have the appropriate level of training and certification to handle them. The classes defined by the Pest Control Act include Domestic, Commercial, and Restricted.

Domestic pesticides are generally those intended for use by the general public in home and garden settings, with lower toxicity levels. Commercial pesticides are meant for use by professionals in agricultural or other specialized fields, often requiring additional training and certification. Restricted pesticides are those that pose a greater risk to health and the environment and are limited to use by individuals who have obtained specific certifications.

However, "Industrial" is not a recognized classification within the Pest Control Act. While industrial use of pesticides might occur, it does not fit into the defined categories established by the legislation. This distinction emphasizes the framework within which pesticide regulation operates in Ontario, focusing on ensuring safety and effectiveness according to the intended use and user proficiency.
