I would echo everything that has been said by my colleagues about political parties. I know we're running out of time for my answer, but one thing that would probably be very effective for all of those electoral district associations that required a search committee and then didn't form one would be some kind of mandatory reporting and disclosure that would require people who are doing this kind of work to actually say what they did. That could then be made publicly available, because the public can judge it as it sees fit, in any direction it wants.
That's a really effective thing for things like corporate boards as well. In Parliament, if you just tell us what you did and why you did it, people will then be able to form their own judgments on that. Social desirability will nudge people in a direction that will make it more open and more diverse.
