Thank you, Mr. Chair.
As you stated, page 1095 of House of Commons Procedure and Practice , under the section on convening a meeting by the chair, states the following: “Committee meetings are convened by the Chair acting either on a decision made by the committee or on the Chair's own authority.”
Therefore, my advice to the chair would be that there are two mechanisms to plan a meeting: Either the committee can agree to a schedule and a specific time and plan for a meeting, or the chair has the discretion to plan meetings on his authority.
