Canadian corn standards and grades

The Canadian Grain Commission defines Canadian grain standards and assesses the grade of grains against these standards. The Grain Grading Guide contains all the standards for Canadian grain. Chapter 17 presents the standards for corn.

The Western Standards committee and Eastern Standards committee review these grading standards and recommend changes when necessary. The committees also select the standard samples of Canadian grain used each year.
