I am pleased at the suggestion that the President of Treasury Board appear before the committee. In addition, I think it is quite reasonable to ask committee members to submit a preliminary list. I think next Tuesday at 5 p.m. is a reasonable deadline.
Of course, once we begin meeting more often, one of the parties or one of the members may want to hear from other witnesses. It is normal practice to be able to add names to the list. It would be more up to the Subcommittee on Agenda and Procedure to meet soon to start planning the meeting schedule.
