Consultation on Glyphosate, Proposed Maximum Residue Limit PMRL2021-10

Notice to the reader:

The online consultation is now closed.


As of 20 July 2021, the period for which comments can be submitted on this consultation has been extended by an additional 45 days from the date of publication. This is based on the level of interest and number of comments received to date, in addition to delays related to the COVID-19 pandemic. The new deadline to submit comments is now 3 September 2021 (120 days from the original date of publication).

Health Canada is consulting on a proposal to establish these maximum residue limits (MRLs) in response to an application from a registrant to align MRLs with those proposed by the Food and Agriculture Organization and World Health Organization’s Codex Alimentarius.Footnote 1 Health Canada has a legal obligation under the Pest Control Products Act to scientifically and impartially assess the risks of all pesticides to human health and the environment, which includes the specification of MRLs in accordance with internationally accepted approaches. Health Canada sets science-based MRLs to ensure the food Canadians eat is safe. The MRLs set for each pesticide-crop combination are set at levels well below the amount that could pose a health concern. If it is determined that an unacceptable risk exists, the product will not be permitted for sale or use in Canada.

MRLs are routinely amended as agricultural practices change both in Canada and abroad. In this case, the proposed MRLs reflect an international use pattern and do not change how the product is used in Canada. Health Canada reviews the supporting scientific data and if it is demonstrated that the residue levels do not represent a health risk of concern, then the revised MRL is proposed. Up-to-date MRLs are necessary to ensure domestic and imported food meets Canadian food safety standards.

Footnote 1

As per the Summary Report issued on May 2019, the Joint FAO/WHO Meeting on Pesticides Residues is recommending to withdraw the current MRL of 2.0 ppm for glyphosate in/on dry beans and to establish an MRL of 15 ppm in/on the dry bean subgroup, except soybeans.

Footnote 2

As per the Summary Report issued on May 2019, the Joint FAO/WHO Meeting on Pesticides Residues is recommending to withdraw the current MRL of 5.0 ppm for glyphosate in/on dry peas and dry lentils, and to establish an MRL of 10 ppm in/on the dry pea subgroup.

How to get involved

This consultation is available for comment from 6 May 2021 to 3 September 2021 (120 calendar days). Open the "Consultation Document" link to access the document.

Interested parties are encouraged to provide comments and suggestions by 3 September 2021.

Next Steps

Before making a decision on the proposed MRLs, the PMRA will consider all comments and scientific information received from the public in response to PMRL2021-10. A science-based approach will be applied in making a final decision. The PMRA will then post the decision, which will include a summary of the comments received on the proposed PMRLs, and the PMRA’s response to these comments.

Reporting to Canadians

Health Canada will make the results of this consultation available on this website. Once the decision on glyphosate is finalized, the established MRLs will be legally in effect as of the date that they are entered into the MRL database, an online query application that allows users to search for established MRLs, regulated under the Pest Control Products Act, both for pesticides or food commodities.

If you have any questions, contact the Pest Management Information Service.

Footnote 1

The Codex Alimentarius Commission, established by the Food and Agriculture Organization (FAO) of the United Nations and the World Health Organization (WHO), develops harmonised international food standards, guidelines and codes of practice to protect the health of the consumers and ensure fair practices in the food trade. The Commission also promotes coordination of all food standards work undertaken by international governmental and non-governmental organizations.

Footnote 2

Note of clarification: The first three rows in Table 2 of Proposed Maximum Residue Limit PMRL2021-10, Glyphosate (Groats/rolled oats, oat bran; Barley bran, pearled barley, wheat germ; Wheat bran), represent the existing MRLs in various jurisdictions. There is no change being proposed to these Canadian MRLs; this is to reflect updated terminology, as indicated in paragraph 1 of the consultation. MRLs are included for ease of reference.
