On the supplementary estimates (B), the last supply day is today. We have to count backwards on this for the time limit for the committee to report the supplementary estimates (B). It would have been last Monday at Routine Proceedings, of course. That's the time frame we have, according to, I believe, Standing Order 81(5).
Secondly, since we don't know what the last supply day will be ahead of time, it's difficult to establish or to have a date on which we are absolutely sure we can report to the House.
Given that, we can always have a study on the supplementary estimates, on the subject matter. The difference between a subject matter study and the one under Standing Order 81(5) is that we cannot vote anymore on each and every credit, because they have been deemed reported to the House.
