Mr. Chairman, a good way to think about it is perhaps not only in terms of cost, because as I said earlier, different situations lead to different costings and also different governments have different ways of accounting for specific expenditures.
The reality is our security practices are not substantially different from other countries where summits have been held in the past. We're policing to essentially the same kinds of standards. It costs what it costs.
Frankly, in response to the first part of your question, I have never been able to find a fully accounted picture of the costs for any summit. Indeed, the Parliamentary Budget Officer and the Auditor General have made the same kinds of comments, that it's very hard to find another example that is equally transparent and equally fully accounting for all of the expenditures. I simply haven't found it.
But the reality is it does cost a fair amount when you cost in all the items.
