Canadian wheat varieties fall into classes and each class is unique. The varieties within each class are grouped by their functional characteristics. For example, varieties in the Canada Prairie Spring Red class have medium hard kernels and medium dough strength. Canadian wheat classes are categorized by Canada Western and Canada Eastern, the regions in which the varieties are grown.
There are 7 classes of eastern Canadian wheat:
There are 8 milling classes of western Canadian wheat:
Each milling class has its own quality and processing characteristics.

Varieties registered as Canada Western General Purpose are not required to meet the strict quality requirements of milling classes. Generally, varieties in this class are not appropriate for milling because of their high starch and low protein content, which affects end-use characteristics of the grain.
Varieties in the Canada Western General Purpose wheat class are typically high-yielding. Due to the combination of high starch and low protein, they are most suitable for uses such as ethanol product or animal feed.
Varieties within this class may look similar to varieties within other classes of wheat.
