I would move an amendment. There are two parts to this amendment.
First I would move that the wording be changed to, “That witnesses be given five minutes for their opening statements; that, whenever possible, witnesses provide the committee with their opening statement 72 hours in advance; that, at the discretion of the Chair..”, etc., as written. That's the first part of the amendment.
The second part of the amendment is concerning the order. I would amend that the wording be changed to, “For the second and subsequent rounds, the order and time for questioning be as follows: Conservative Party, five (5) minutes; Liberal Party, five (5) minutes; Bloc Québécois, two and a half (2.5) minutes; New Democratic Party, two and a half (2.5) minutes; Conservative Party, five (5) minutes; Liberal Party, five (5) minutes.”
