Sure. Let me take a stab at this one.
When you look through the main estimates, to give you one example, you'll note there are some examples of significant reduction in spending in certain departments compared to the previous year. That's probably a pretty good signal that there's been a sunset or a wind-down of some particular program.
We've had a lot of that in the last couple of years, with the wind-down on Canada's economic action plan as a good example. As you recall, in Budget 2009 there were extensive new programs, stimulus measures, but there was a specific date saying those will be wound down two years hence. That's where you start to see that in these estimates documents. If these programs were completed by March 31, 2011, it's after that period, so you're starting to see now where these programs drop off.
A lot of these were infrastructure projects. They were large infrastructure projects. You can clearly see—such as for FedDev, the Federal Economic Development Agency for Southern Ontario, the clean energy fund, CFI, which is the Canada Foundation for Innovation—where the evidence of that drops off. Because the specific stimulus measures are no longer active, they are dropping off our estimates sheet.
