The Pesticides Management Code
Protecting the environment and health in our green spaces
Updated: February 2021
The Pesticides Management Code introduces regulations controlling
the storage, sale and use of pesticides. It promotes an environmental
approach aimed at limiting the health risks that these products entail,
particularly to children and the environment. Its targets are lawns as
well as childcare centres and elementary and secondary schools.
The use of pesticides may represent a health risk and cause
water, air and soil contamination. For example, residues from pesticides
used for parks, golf courses and lawn treatments may infiltrate our rivers
and streams. A study
carried out in Québec reveals the presence of pesticides used in urban areas
in the waste water from water purification plants. These include herbicides
such as 2,4-D, mecoprop and dicamba, as well as insecticides such as
diazinon and carbaryl.

These regulations affect the storage, preparation and
application of pesticides in the green space maintenance sector. Permit and
certificate holders targeted by the Regulation respecting permits and
certificates for the sale and use of pesticides must comply with the
regulations of the Code. These include:
holders of a Class C permit “Remunerated Work Permit,” Subclass C4 “Application in Ornamental
holders of a Class D permit “Non-Remunerated Work Permit,” Subclass D4 “Application in Ornamental
holders of a Class CD certificate “Certificate for the Application of Pesticides,” Subclass CD4 “Certificate
in Ornamental Horticulture”.
Individuals tasked with applying pesticides to lawns may do
so without being certified as long as the pesticides meet specific health
and environmental criteria. The conditions governing this exemption are
