Thank you.
I'd like to take the opportunity to echo what Mr. Oliphant is saying. Five minutes is a short time for someone as loquacious as I am, and our experts are dealing with far more complicated topics than we sometimes deal with in our short conversations.
I think perhaps the wording ought to be “subject to the discretion of the chair” instead of “in the discretion of the chair”, because for the five minutes it's not either five or nothing, it's five or more. Saying that “subject to the discretion of the chair” five or more minutes would be given to speak would allow that recognition, if we look at the timing of the first and second rounds, for example, depending on whether we have one witness or two or three. If you have three, five minutes is as much as you can fit into a certain length of a meeting, but if there's only one witness.... Often, obviously, we have ministers speaking for 10 minutes or more, and introductions.
I think there is a fair bit of discretion used in these meetings. I think it would be better to state it as not quite open-ended, but that it can be as low as five minutes and it can be longer at the discretion of the chair, and that perhaps, subject to the discretion of the chair, five minutes or more may be allocated to the speaker. That would give us some flexibility without mentioning more than one number.
