The purpose of this paper is to assess the success of the Ontario Wheat Producers' Marketing Board in fulfilling the need which prompted its formation. Its prime objective was to increase, by various means, the proceeds received by producers from the sale of winter wheat. This paper will focus on the Board's efforts to raise these returns by means of its minimum price policy. Empirical problems greatly hindered the evaluation. The conclusions reached have largely been derived from logical deductions rather than from refined statistical techniques.
