Protection and prevention

Pesticides should be used only as a last resort, with precautions and in a responsible manner.

Pesticides are sometimes necessary, such as for a cockroach, bed bug or rodent infestation. In this type of situation, you should hire a certified pest control specialist who has a permit and a certificate issued by the Ministère du Développement durable, de l’Environnement et de la Lutte contre les changements climatiques (MDDELCC). Carefully follow the pest control specialist’s instructions on how to prepare the area prior to treatment. Follow the instructions that he gives you during the treatment and for the period after treatment too. Each step is essential to ensure the treatment is effective and to protect your health.

Stratégie phytosanitaire québécoise en agriculture

The Ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Québec (MAPAQ), the MDDELCC, the Ministère de la Santé et des Services sociaux and the Union des producteurs agricoles developed the Stratégie phytosanitaire québécoise en agriculture This hyperlink will open in a new window. (SPQA) (in French only). The strategy has several objectives:

  • To reduce the health and environmental risks of pesticides
  • To intensify integrated pest management for agricultural crops
  • To increase monitoring of pesticide residues in food products

Regulation of the marketing and use of pesticides

The Government of Canada, the Government of Québec and some municipalities regulate pesticides.

Pesticide registration

To be imported, sold or used in Canada, a pesticide must first be registered, that is, approved in accordance with the Pest Control Products Act. Health Canada’s Pest Management Regulatory Agency (PMRA)administers this Act. 

PMRA evaluates every pesticide to ensure compliance with the most stringent health, safety and environmental protection requirements. It must also ensure that:

  • The pesticide is effective
  • The pesticide label provides directions for safe use
  • The pesticide residues that may be found on or in food products are not harmful to consumer health

Framework for the sale and use of pesticides 

The sale and use of pesticides are governed by laws and regulations that are intended to protect health and the environment. The application of these provisions ensures that:

  • Only the least toxic and safest pesticides are readily available to the general public
  • The most toxic pesticides are restricted to professional and specialized use
In Québec

In Québec, pesticide use is regulated by the MDDELCC pursuant to the Pesticides Act. The MDDELCC developed the Pesticides Management Code to regulate the sale and use of pesticides. The Code’s provisions are intended to better protect the environment and health, especially children’s health.

Municipal regulation of pesticide use

Since the early ’90s, many municipalities in Québec have regulated pesticide use on their territory. These municipalities must ensure that their regulatory provisions comply with the MDDELCC’s Pesticides Management Code.
