Of course you're going to want the data that looks at very specific rules, and we have some of that when you think about cost-benefit analysis. There's a lack of sector-specific data.
I would say that the biggest thing that's missing is a fairly simple and straightforward aggregate measure of the total burden of regulation. Here, we have a tendency to want to make the perfect the enemy of the good, but I would look at both Manitoba and British Columbia as good examples.
Twenty years ago, British Columbia set about reducing its burden by one-third in three years. They've actually cut it by about 50%, and they have a fairly simple way of measuring it. Is it perfect? No. Has it driven a lot of good changes and has it reduced the regulatory burden for citizens? Yes. They also do an annual report where they look at other things outside of the measure that have improved the lives of citizens—for example, simplifying forms for welfare applications.
