Hinshaw has said in the past that she doesn't make policy decisions. She provides her professional opinion about what should be done, but it's up to the policy makers and elected officials to actually put in restrictions and mandates.
Exact quote: "I was not elected by Albertans," she said. "The final decisions are up to elected officials who were chosen by Alberta. This is how democracy works."
I doubt her career/credibility will suffer much. The leaked tapes from last year showed how the politicians ignored medical expert advice from Hinshaw and others.
