I don't know anything about the performance targets you mention or the health system in Quebec, but I would be much more worried about how performance targets can be used to encourage doctors to give out sketchy drugs (like the COVID vax) or punish doctors who don't do as the state wants (like decline transgender surgeries).

Also even without malice you can't judge a doctor's worth from statistics and if you tie their salary to some target (like the number of patients they see) then they will do whatever it takes to hit that target even if it makes them a worse doctor and the less scrupulous doctors will game the system using technicalities and lies. And this is all assuming the people setting the targets are competent, which they likely won't be.
