Companies that sell or use commercial pesticides must hold the appropriate permit. Sales staff and pesticide appliers must hold a certificate. These obligations are set forth in the Regulation respecting permits and certificates for the sale and use of pesticides This hyperlink will open in a new window.. Read the following webpage for more information: Permit and certificate applications.

In Québec, laws and regulations (including the Pesticides Management Code This hyperlink will open in a new window.), regulate the storage, sales and use of pesticides in order to limit their adverse effects on the environment and health and to reduce their use. In addition, some municipalities regulate pesticides within their boundaries, based on specific local conditions.
