It's a great question. I have just a couple of comments.
Vote structures are not static constructs; they change with time. They change as programs are introduced or changed, for example, or when reporting and accounting centres change. We talked about the example of reflecting tax expenditures as a voted appropriation in our estimates.
The votes are reviewed and approved by our Treasury Board and they're done on a ministry-by-ministry basis. There isn't a general template for how a ministry's vote and item structure are put together. There is some flexibility and to some extent some varying level of detail in what those votes look like, but by and large, I think we have a fair bit of program-level detail associated with our votes. I don't have the number off the top of my head, but we have many, many votes in each of those ministries, so those general overarching categories of votes are rare or more unusual, and certainly not the norm.
