"four principles: freedom, fairness, responsibility and respect."

Agreed.

Canada is free to establish a system to provide its citizens with a stable, secure supply of quality food at an affordable price.

Fairness: the price that dairy farmers receive is determined by a formula that is based on an averaged cost of production. Farmers in the non-supply managed sectors are subject to the uncontrolled ups & downs of production volumes which of course affect farm-gate prices. Consequently, most Canadian farmers' income has to be supplemented by off-farm jobs.  

Responsibility: food security should matter to Canadians. Eventually something will interfere with our globalized, import-dependent, just-in-time food supply chain: a grain or livestock infestation, an oil supply/transportation crisis, a climate-induced crop failure, etc.  It is prudent for every nation to more or less feed its population.

Respect: our hard-working farmers should be respected and supported by the other 98%.
