Open market refers to all grain marketing transactions outside of the Canadian Wheat Board. For example, canola may be sold to a processing plant where they make canola oil or it may be sold to an elevator company for resale on the Canadian or export market. Private agreements between producers are also open market transactions. Producers of alternative crops such as mustard, canary seed, triticale, lentils and sunflowers may choose to market their grain or oilseeds by using a contract. The producer agrees to grow and produce a crop that will be sold to the buyer at a pre­established price. The contract purchaser of the crop then markets it on the open market. Because there are a limited number of buyers of these specialty crops, contract marketing is a small portion of the marketing techniques used in the grain and oilseed industry.
