Information and notes about the Official Grain Grading Guide

• The Guide is used by Canadian Grain Commission grain inspectors as a complete reference on the grading of grains, oilseeds and pulses.
• It is reviewed and revised to incorporate changes to grade specifications and tolerance levels recommended by the Western and Eastern grain standards committees and to update definitions and grading procedures.
• For an explanation of grading factors, procedures and technical terms used in the Guide, please consult the glossary.
• The web version of the Official Grain Grading Guide is a document controlled under our ISO provisions.
• The web version will be updated as and when changes are made. Copies printed from the web site are not controlled.
• Users of printed copies should be aware that changes may occur without notification.
• Users of printed copies are encouraged to check the web version on a regular basis to ensure they are working with a current version.
• Unless a grain variety has been registered by the Canadian Food Inspection Agency, it is eligible only for the lowest Canada Grain Act grade.
