It's a whole new session, so what happened before, procedurally speaking, is not in front of the committee right now. If the committee wants to follow up on these studies, I would suggest that every motion be readopted one by one and that the committee undertake a study on what it wants to do.
Also, we have some wording to import into the session with respect to whatever happened during the last session. For example, it would be, “Pursuant to Standing Order 108(2), the committee undertake a study on [subject] and that the evidence and documentation received by the committee during the first session of the 43rd Parliament on the subject be taken into consideration by the committee in the current session.”
That would be the appropriate way to continue a study that was started in the previous session. It would be one by one. The motion states “all substantive motions”. I don't know how many motions the committee adopted during the last session, but it means that all of them would be imported.
