The Liberals could make some easy, win/win concessions to the US on trade if they really wanted to. They are the only party that could afford to dismantle supply mismanagement, electorally speaking. And Blubber Dougie would fold like a cheap tent on the booze ban if Carney insisted. But Canadians seem to prefer the passive aggressive route instead.
The U.S. has also complained about Canada’s administration of dairy import quotas created under USMCA and raised concerns over milk pricing policies and market access for U.S. dairy products. Prime Minister Mark Carney’s government has said previously supply management will not be on the negotiating table.

I don’t think that’s true. The dairy lobby is not just powerful on its own, it’s connected to a lot of other special interests. If the Liberals dismantle supply management the party will survive, but everyone involved in the decision will be driven out of politics and impoverished forever – assuming they’re even allowed to get to the point of dismantling the cartels.
The wild card here is the CCP. I don’t know if they care one way or another about supply management except as an indirect way of messing with the US. If the Chinese decide it’s in their best interests for supply management to fall, Quebec won’t be able to stop them.
the only thing North American socialists ever got right was that Free Trade is bad.
Our trade protectionism good, yours is bad
Pssst … Canada … Animal Farm was a CAUTIONARY tale … not a blueprint.
