Yes, sir. Thank you for your question.
In any major government project, there are always all kinds of unforeseen events.
We are also dealing with foreign suppliers. We have exchange rate risks. There are interest rate risks. There can be inflationary risks in terms of employment and contracts. If key suppliers go out on strike in the middle of a project and they come back and we have to pay them more money, there are risks related to that. Then there are specific project risks, depending on the type of project. If we are rehabilitating buildings in the parliamentary precinct, for instance, there can be risks related to lead pipes and old fashioned plumbing, and there can be asbestos.
In the case here of infrastructure.... The point here, Mr. Ayoub, is that for all of these projects there are considerable unknowns, so we would build in contingency at the very beginning of the project when it's approved by cabinet, by the Minister of Finance, and by Treasury Board. There are known costs, and then there are certain amounts set aside for contingency to factor in the unknown costs. That's simply prudent project management.
