There are so many cases. In some cases the right decision.... It's hard. You do the best you can at the time.
But one of the main things, in my mind, would be continuity. You come up with issues, you want to help, and consult as broadly as possible with the provinces—and internationally, if you have to—and develop policies and directives. Once you've decided what they are, stick with them as much as possible.
Regarding efficiency, the industry, the idea of continuity, and not changing your mind would be very useful.
