I'm not sure how much control we can have over the minister's time, but I think that in the request that is sent to the minister, we could indicate that we want him here for such and such a length of time. I know there have been some ministers who have had to leave early, but it has been my experience on this committee that when they've come, they've stayed until the time was exhausted. I don't know if that'll change. I can't comment on that.
Are you suggesting that when we do invite a minister, we say that we want him for a minimum length of time?
