Pesticide application on green spaces, golf courses and for pest management

Pesticides are sometimes used for the maintenance of green spaces and golf courses, as well as for pest management. Pesticides should be used as little as possible and products that are least harmful to human health and the environment should be preferred. This is why companies must be licensed and users certified to apply pesticides in these sectors. Compliance with specific rules is also mandatory.

Permit and certificate requirements

If your company applies pesticides for green space or golf course maintenance, it will need to hold a Sub-class C4 or D4 Application for maintaining green spaces permit.

If you personally apply pesticides, you will need to hold a Sub-class CD4 Application for maintaining green spaces certificate or be supervised by an on-site holder of this type of certificate. See the list of conditions This hyperlink will open in a new window. (French) for details on lawn application of pesticides without holding a certificate.

As of July 6, a Sub-class C11 or D11 permit, “Application on golf courses,” will be required for this activity. If you personally apply the pesticides, make sure you hold a golf course application certificate (Sub-class CD11) or work under the supervision of the holder of such a certificate.

If your company applies pesticides for pest management, it will need to hold a Sub-class C5 or D5 permit Application  for pest management permit.

  • Methyl bromide
  • Carbon dioxide
  • Sulfuryl fluoride
  • Ethylene oxide
  • Phosphine

If you fumigate with the above pesticides, you must hold an Application by fumigation (sub-class CD6) certificate or work under the supervision of a holder of this type of certificate who is on-site when the activity is carried out.

If your company applies pesticides for the maintenance of indoor plants, make sure it holds an Application in Buildings for Horticultural Purposes permit (Sub-class C10 or D10).

If you are a permit holder, you must keep and retain a register of your pesticide purchases, sales and utilization. Depending on your type of permit, you may use the registre d’achat et d’utilisation de pesticides – permis de catégorie C (XLSX 80 Kb) (French) template or the registre d’achat et d’utilisation de pesticides – permis de catégorie D (XLSX 51 Kb) (French) one.
