Grain grading changes announced for the 2022-2023 crop year


The Canadian Grain Commission (CGC) has announced a series of grading changes that will come into effect this upcoming crop year. The CGC says the changes come after consultations with stakeholders through the Western Standards Committee and Eastern Standards Committee.

The grading changes include the following revisions and considerations:

Mildew standards for eastern and western red wheats. 

  • Current mildew standard samples for Canada Eastern Red Spring (CERS), Canada Western Red Spring (CWRS), and Canada Western Red Winter (CWRW) wheats are being replaced.
  • Updated standard samples for No. 1 and No. 2 CERS wheat will be effective July 1, 2022 in eastern Canada and No. 1 and No. 2 CWRS wheat will be effective August 1, 2022 in Western Canada.
  • The mildew standard for Wheat, No. 3 CERS, Wheat, No. 3 CWRS, and Wheat, No. 3 CWRW will no longer be used as a grading factor for those grades.

These changes are being put in effect after the Canadian Grain Commission determined mildew had minimal impact on flour yield and refinement, dough properties, and baking quality.

Splits tolerance for No. 2 Canada Green Peas

  • The splits tolerance in No. 2 Canada Green Peas will be changed from 1% to 3% effective August 1, 2022 across Canada.

The CGC says this change is in response to feedback that the 3% splits tolerance better reflects how the sector is handling and exporting No. 2 Canada Green Peas.

Tolerance for inconspicuous admixture in canola

  • Effective August 1, 2022 across Canada, the tolerance for inconspicuous admixture in the No. 1, No. 2 and No. 3 grades of canola will be changed from 5% to 1.0%.

This is in response to quality concerns that were discovered with canola samples that contained 5% admixture and will help to ensure Canada’s reputation for high-quality canola.

Coloured beans will need to be registered to be eligible for the highest grades

  • Effective August 1, 2022, only Canadian Food Inspection Agency (CFIA) registered varieties of coloured beans will be eligible for the highest statutory grades for beans in Canada.

Coloured beans include but are not limited to black beans, cranberry beans, pinto beans, red kidney beans, red Mexican beans, and yellow eye beans.

Excreta tolerance for domestic mustard seed

  • The tolerance for excreta in the No. 1, No. 2 and No. 3 grades of domestic mustard seed is being updated from 1 kernel-size piece per 500 grams to 0.01% effective August 1, 2022.
