Cosmetic Pesticide Changes - Enhanced protections in public spaces - Safer application in residential uses

What This Means to You

Home Owners

Homeowners now have the flexibility to use any pesticide registered with Health Canada on their lawn. All users must follow the directions provided on a product's label.

Lawn Care Professionals

Lawn care professionals must hold a licence, only apply federally-registered pesticides, and follow all Health Canada approved labelling.


These changes do not conflict with the responsibilities of weed supervisors under The Noxious Weeds Act. Out of an abundance of caution, pesticide use is now restricted at municipal playgrounds, picnic areas, and dog parks. These areas will be defined in pesticide use permits. The application of specific cosmetic pesticides in low-risk areas such as municipal boulevards, sidewalks, rights-of-ways, and fairgrounds is now allowed.


The sale of prescribed pesticides is no longer restricted. When selling federally-registered pesticides, retailers no longer have to:

  • lock up products and prevent public access
  • ask the buyer’s plans and decide if they are compliant
  • give facts to the buyer on compliant use.
