NOTIFICATION  
 
1. Member to Agreement notifying:   CANADA  
If applicable, name of local government involved: 
2. Agency responsible:   Pest Management Regulatory Agency (PMRA), Department of 
Health 
3. Products covered (provide tariff item numbe r(s) as specified in national schedules 
deposited with the WTO; ICS numbers should be provided in addition, where applicable):  Chlorpyrifos (ICS: 65.100.10) 
4. Regions or countries likely to be affected, to the extent relevant or practicable:  not 
stated  
5. Title, language and number of pages of the notified document:   Proposed Amendment to 
the Food and Drug Regulations (1341 - Chlorpyrifos) (available in English and French; pages 161-165). 
6. Description of content:   
The Pest Management Regulatory Agency (P MRA) of Health Canada has initiated a 
process to re-evaluate and to determine the conditions of acceptability for pesticide active 
ingredients that were registered in Cana da before 1995, along with their currently 
registered end-use products.  Re-evaluation is the review of pesticide active ingredients and 
their end-use products on the basis of updated data and information to determine whether, 
and under what conditions, their con tinued registration is acceptable.  
 
Therefore, as a result of this first stage of th e re-evaluation of chlorpyrifos, it was decided 
that products containing chlorpyrifos could not be used in Canada on tomatoes after 
31 December 2003.  Chlorpyrifos is not regist ered for use on apples or grapes in Canada. 
The PMRA also proposes to mitigate the acute  dietary risk concerns by decreasing the 
Maximum Residue Limits (MRLs) for chlorpyrif os in apples, grapes and tomatoes to 0.01 
p.p.m.  After the review of all available data , the PMRA has determined that following this 
amendment, both the acute dietary risk and the chronic or lifetime risk from foods treated with chlorpyrifos will not be a concern fo r the general Canadian population or any 
population subgroup, including infants and childre n.  Since chlorpyrifos is still registered 
for use on other commodities in Canada, this proposed MRL is being established to cover 
residues as a result of the misuse of chlorpyrifos and residues found in imported 
commodities.
