If I may, Mr. Chair, I'd like to say something.
While I'm eager to hear what the Official Opposition has to say about this, I have to point out that I once chaired a subcommittee and in my estimation, having a parliamentary secretary as a member is an added bonus, precisely for the reasons you gave. Even though the parliamentary secretary is only one person, when a vote is taken—the subcommittee already operates by consensus— he can convey the government's perspective on issues and steer the discussion in certain directions. I believe his presence helps the committee to do a better job and to organize its work. By knowing what the government is planning, MPs can work more effectively. On a more personal note, I have to say that it makes the Chair's job easier, because he must always remain somewhat reserved.
