Investors confirm what CWB supporters have known all along. Small farmers are unlikely to survive in a "voluntary" market. 
An article from Potash News from Oct. 20, 2011 exposes what farmers will dread and marketting companies will enjoy:
"The outcome of Canadian wheat farmers in Alberta, Saskatchewan and Manitoba selling on open markets will likely be falling grain prices as producers compete for market share. The impacts of change will also make it easier for cereal traders to buy directly from Canadian producers, which would also increase the need for hedging instruments by companies like ICE or MGX mentioned above. It is also likely that considerable consolidation could take place amongst Canadian producers as smaller farmers are squeezed at the margins when forced to market their own grains."
