I think something that I would like to see more of in the U.S. and Canada is research by the government into the costs and benefits of various changes. I've found that the level of study that goes into some changes—having done some of it myself—really leaves a lot to be desired. I can't speak so specifically to the Canadian context. However, in the U.S. context, the way that these codes are written, it's often a bunch of unpaid volunteers in a room puzzling things out together.
If you're trying to evaluate the costs and the benefits, it doesn't do a great job of doing that in a very precise way. If you don't understand the costs and you don't understand the benefits, it's hard to balance them very well.
