Remember when it was "anti American" to criticise the US? The one good thing that has happened since Trump is that it is now OK to criticise and as a result all kinds of new information is rolling out. Our supply management has been in the crosshairs for ever but until now I've never heard that the US limits dairy imports to 3% of total, that its imports into Canada exceed our exports into the US  by about $500 million, that they suffer from over production (which our supply management prevents) that changing market conditions can lead to many dairy farmers going out of business (which again, our supply management can largely ease)In other words, supply management is looking pretty good against the so called "free market" but heavily subsidised through taxes US model. Lets hope Trudeau sticks to his promise of protecting our dairy farmers.
