Mr. Chair, it's a bit of both.
You have cases like Shared Services Canada.
Of their lapse, a good portion of that was planned. They had a reduction that they had to make.
There are other cases where programs are very much demand-based. Agriculture is an example where we're offering insurance programs, and the department does a forecast of what they think the take-up of their program will be, but sometimes it's not as high as expected.
I mentioned Natural Resources Canada is another example, and Veterans Affairs. Veterans Affairs is very much driven by how many applicants they have for their programs. So those are a bit different. They are very much demand-based.
Then you do have the odd project where there are simply delays. Bridges are complicated and sometimes there are delays in spending, so the forecasted spending has been greater than the actual spending.
As you mentioned, there is a theme here of under-spending, which is good. Overspending is a bigger problem. I'm pleased to say there are no cases of departments exceeding their vote. But you really have to get down department by department to understand why they didn't spend their money because there's not one reason government-side.
