When pesticides are used on crops or when animals are fed crops treated with pesticides, residues may remain in or on the food when it is sold. Before registering a pest control product for use in Canada, the PMRA must determine that consumption of the residues that are likely to remain in or on the food when the pesticide is used according to label directions will not pose an unacceptable health risk. This amount is then legally established as a maximum residue limit (MRL) under the Food and Drugs Act  (FDA).
These MRLs apply to both domestic and imported food.
In order to prevent residues in or on the imported
food from posing an unacceptable health risk, MRLs
are also established for pesticides not registered
for use in Canada and for Canadian registered pesticides
with respect to uses that are not authorized in Canada.
If residues exceeding an MRL are found, the food is
considered adulterated and is prohibited under the
FDA from sale in Canada.
The Food Directorate, Health Products and Food Branch,
Health Canada maintains webpages that contain
a Health Canada consolidation of the Food
and Drugs Act and Regulations where MRLs tables for pesticides are listed. This unofficial consolidation is
updated periodically and contains all amendments
published in the Canada Gazette, Part II
up to the date indicated.
This webpage contains the texts of publications pertaining to proposed MRLs pre-published for comments in Canada Gazette, Part I, Interim Marketing Authorizations* (IMAs) published in Part I and currently in effect, and new MRLs published in Part II since the latest Health Canada consolidation.
*An IMA is a mechanism that bridges the time between completion of the scientific evaluation of certain enabling amendments such as the establishment of MRLs for new uses of a pest control product, and publication of the approved amendments in Canada Gazette, Part II
