Pesticides Act is chiefly concerned with protecting the environment
through proper handling, transportation, storage, use, and disposal
of agricultural chemicals. These matters are also crucial to
protecting the health and safety of individuals who work with
Successful completion of Ontario's Pesticides Safety Course
is a legal requirement for use of many common pest control products.

The Pesticides Act is administered by the Ontario Ministry of
the Environment (MOE). Following is a brief synopsis of the
Act's requirements for safe transportation and storage of pesticides.
- Never leave pesticides unattended in a parked vehicle,
unless the vehicle is locked or parked in an area to which
public access is denied.
- A sign indicating " Chemical Storage Warning-- Authorized
Persons Only" must be displayed on unattended parked
vehicles containing pesticides.
- Vehicles transporting more than 500 liters of pesticides
must be placarded with a chemical warning sign at all times.
- Pesticides must be stored in an area that is used exclusively
for this purpose. Separation from storage facilities for
other commodities must be sufficient to prevent cross-contamination.
- Pesticides and pesticide adjuvants (e.g. emulsifiers,diluents,
spreaders, and dyes) are the only items to be stored in
this building, room, or part thereof.
- If the pesticide storage is later to be used for other
purposes, it must first be decontaminated.
- Insecticides, herbicides and fungicides should be stored
separately from each other.
- The storage area must be screened and ventilated to the
- Chemical storage warning placards (available from OMAF
and MOE) must be posted on the door(s) of the storage area.
- The storage area must be lockable to control access.
One staff member should be responsible for security. No
one should be able to enter the storage area without authorization.
- There must be no floor drains, unless they flow into
a separate holding area which can be pumped out. Such spills
must be disposed of in accordance with Regulation 309 of
the Environmental Protection Act.
- Protective clothing (i.e. neoprene or rubber gloves,
hat, coveralls, boots, eye and respiratory equipment, etc.)
must be readily available to protect handlers from adverse
effects of the stored pesticides. Protective gear must be
stored in a manner that prevents its contamination (e.g.
in an adjacent room or in polyethylene bags.)
- Post emergency telephone numbers in a prominent place.
This list must include the doctor, poison control centers,
fire, police, Spills Action Center, and the MOE's Pesticides
- Absorbent material (i.e. sawdust, soil, or rags) should
be available in sufficient quantity to clean up any spills
or leaks from containers. The MOE's Pesticides Safety Handbook
describes procedures for equipment decontamination.
- Pesticides storage areas must be cool and dry to prevent
product breakdown or inactivation. Check product labels
for winter storage guidelines.
- Pesticides should be stored in their original, labeled
- Any new pesticides storage structures should be placed
so as to avoid contamination of watercourses in the event
of a spill, explosion, or fire. Existing buildings and surrounding
terrain should be modified to ensure containment of runoff.
- Wash-up facilities with adequate supplies of soap and
water should be available.
- The MOE must be notified of any fire or spill where there
is an environmental impact. Any fire, spill, or theft of
pesticides must be reported to the Spills Action Center.
- Only trained personnel wearing adequate protective equipment
should be involved in any spill cleanup.
