I have relatives that are dairy farmers in Ontario and they seem to be doing ok. There's some kind of collective in place that establishes production quotas and you have to pay for the right to produce. Maybe more commodity products could benefit from this type of planning.
It makes Canadian dairy products rather expensive. Helping businesses collude to drive up prices and increase profits really should not be the role of government. Cartels are good for their members, but not for the rest of society.

Well, that's one way to look at it. Another way is to say it stabilizes a strategically important sector and establishes a minimum wage for dairy farmers. I'd rather pay more for milk than have desperate farmers killing themselves at record rates. There's a societal cost to that as well.
This is also why milk costs 50% more in Canada than in the US. Still, a reliable supply of food reduces the risk of famine which is more important than a purely competitive market.
