What If I am a Researcher and I Need to Buy and Use Pesticides?

A person is exempt from a structural or land exterminator licence, and a permit, and from Section 9 of Regulation 63/09 under the Pesticides Act in order to buy or use a Class B, C or D pesticide for research purposes or a test (Reg. 63/09, Ss.10 (1)). 

The researcher must:
 use the pesticide on properties designated for research, and

 be affiliated with a research centre, university or college, or

 be a professional researcher from industry or government, or

 be supervised by a professional researcher.


If you are a researcher but do not meet these requirements, you may be considered for a research exemption as prescribed in ss. 10 (2) and (3).

If you are a researcher and you need to buy and use pesticides, you must write a letter requesting approval from the Director under the Pesticides Act.

Address your letter to:
 Director under the Act
Ontario Ministry of the Environment, Conservation and Parks
40 St. Clair Ave. West 7th Floor
TORONTO, ON  M4V 1M2
Phone: 416– 327-5199

In your letter, explain:
  • · your research position with the research facility, if applicable
  • · the pesticides you need to buy and use
  •   state the PCP Act number or the active ingredient and concentration
  • · the purpose and location of your research, and
  • · whether you have a federal research permit (if so append a copy).
You must follow any conditions specified in the approval document, and carry a copy of the approval with you when using or handling pesticides.  When you buy pesticides, show a photocopy of your letter or written approval from the Ministry of the Environment, Conservation and Parks to the vendor.  The vendor may photocopy the letter if the product requires a record of sale.

Restricted Entry Intervals

Restricted Entry Interval (REI) is the period of time after a pesticide has been applied that agricultural workers or anyone else must not do hand labour tasks in treated areas.  The REI allows the pesticide residues and vapours to dissipate to safe levels for work to be done. Hand labour tasks involve substantial worker contact with treated surfaces such as plants, plant parts or soil.  Examples of these activities include: ·   harvesting, detasseling, thinning, weeding, scouting, planting, mowing, roguing, and packing produce into containers in the field or greenhouse. You can only do these tasks after the Restricted Entry Interval has ended.

Water Soluble Packages

Water Soluble Packages (WSP) are designed to reduce exposure during mixing and loading.  However, the Agricultural Handlers Exposure Task Force (AHETF) found that ►   users were more exposed when using Water Soluble Packages than Wettable Powders. Exposure occurred when users sprayed high pressure water on the packets and/or intentionally broke the packets to help them dissolve.   Use Water Soluble Packages properly to reduce exposure.   Follow these handling and mixing instructions developed by the United States Environmental Protection Agency and the AHETF. Handling Instructions •   Mix in the spray tank only.   •   Keep the WSP intact. Do not cut or puncture the WSP.  Do not break or release the contents. •   Keep the WSP in the outer packaging until just before use. •   Keep the WSP dry until adding it to the spray tank. •   Reseal the WSP in its outer packaging to protect any unused WSP(S). •   Handle with dry gloves. If the WSP tears or ruptures before or
