Supply management costs Canadians $2.6B/y, while subsidies cost Americans $4B/y.  Since the US is 9 times bigger than ours, the Canadian dairy farmers are getting 5 times more help per capita.  While laxer rules on hormones in the US are an arguement, our supply management scheme also puts up barriers to EU milk products and organic milk from the US.  There's is no justification for this.
