What is required in addition to an exterminator license to legally apply a class B or C pesticide containing picloram in Ontario?

To legally apply a class B or C pesticide containing picloram in Ontario, obtaining a permit is essential. This requirement is in place because certain pesticides, like those classified as class B or C, are potentially more hazardous and require strict regulatory oversight. The permit ensures that the applicator adheres to safety standards and follows the guidelines established by regulatory bodies, which often include considerations related to environmental impact and public safety.

The necessity of a permit stems from the need to monitor and control the use of more potent chemicals to mitigate risks associated with their application. By obtaining a permit, the licensed applicator demonstrates compliance with provincial regulations and confirms their intention to utilize the pesticide responsibly, thus protecting both the environment and public health.

While operator training certificates, environmental assessments, and safety data sheets are important components of pesticide application, they do not replace the requirement for a permit when dealing with substances like picloram that fall under more stringent regulatory categories.
