One of the important changes that could be included in the main estimates, which is partially included in the RPPs, is much better accounting down to the program level and actual projects and determining how those projects change over time.
For instance, taking a look at HRSDC, how is EI funding changing over time? How is employment in the EI office changing over time? You can certainly get some of that detail in the RPPs, but it's not necessarily included in the main estimates, or you'd have to put it together, in any event. Certainly I think that reports by standard object—that is to say, by salaries and contracting, rent, utilities, and so on—is a useful way of breaking that down.
I think that breaking it down by the actual budget lines within each of the departments is also a useful way of determining what's happening in that department. I think parliamentarians would also find it quite interesting to see how that's changing over time.
It's only once that information starts to be published and you can compare past to future to find out why it's changing that parliamentarians can ask more pertinent questions about government spending and investigate it more correctly, frankly.
