The leader of the opposition has requested, and from my understanding it was adopted yesterday in the House, that consideration of the main estimates for the environment committee be extended beyond May 31, at which point they otherwise would have been deemed reported back. The new deadline can be viewed, I guess, as to some extent still up in the air, because the committee on the extension would have up to ten extra sitting days to consider the main estimates. However depending when the last allotted day is, which is basically the last opposition day of the current supply period, this committee would have the opportunity to report the main estimates back up until the day immediately preceding the last allotted day.
I myself don't have confirmation when that last allotted day is; I'm not sure whether the government has set it officially yet. But for example, if it were to be on Thursday the 7th, the main estimates would be deemed reported back automatically to the House. So the last opportunity the committee would have, if in fact the last allotted day is on the 7th, would be to consider the main estimates no later than the day immediately preceding that, which would be the 6th of June.
