Canada’s Liberal Party Prime Minister Mark Carney is no piker when pushing them.

…he suggested he has prepared for a possible military invasion by American forces. “I think you have a responsibility in these roles to look at extreme tail risk,” Carney said recently. “That’s just risk management. That’s not a base case, but it would be irresponsible not to” prepare.

Given that level of irrationality, how would it be possible to reach any sort of trade deal with Canada?
