A quasi-governmental self-financed agency, established in 1935, that markets Canadian wheat, oats, and barley on behalf of producers. Commercial grain is put into annual marketing pools by grade, with the pool period lasting 12 months and ending July 31. The CWB markets the grain to domestic and foreign buyers, with unsold grain transferred to the pool established for the next year. The overall procedure ensures a uniform per-bushel return, excluding storage costs, to all producers for each grade, regardless of the time they deliver their grain to elevators. The flow of grain from farm to terminal is closely regulated. The CWB also works to develop new markets for Canadian wheat and has authority to enter into long-term supply contracts with foreign countries.
