Mr. Chairman, there are a number of formulas that are used in government for costing out impacts and so on and so forth. In this instance, we don't have anything of that nature. I think departments are out there trying to deliver housing and so on and I think they do as well as they can in reporting back to us what the impact is going to be. But, there always has to be some adjustment at the end. I understand what the Member is saying. It would be nice if we lived in a world where we could forecast exactly the kinds of changes that are going to occur. As much as we try, we are not perfect, Mr. Chairman. I will endeavour to be better at it in the future but, at the present time, it's not a fine art. Thank you, Mr. Chairman.
