True or False: All pesticides must be registered under the Pest Control Products Act before being sold or used in Canada.

The statement is true because all pesticides must indeed be registered under the Pest Control Products Act before they can be sold or used in Canada. This registration process ensures that products are evaluated for their safety, efficacy, and impact on the environment and human health. The act requires detailed information about the pesticide's use, formulation, and potential risks, facilitating informed decision-making by consumers and professionals.

Additionally, the critical nature of pesticide regulation in Canada aims to prevent the sale and use of potentially harmful substances without thorough assessment. This comprehensive approach to pest control is essential for maintaining public health safety and protecting the environment, which is why all pesticides, regardless of whether they are commercial, residential, or imported, fall under this statutory obligation.
