I think it's impossible at any point in time for one to have accurate numbers, whether you are looking at the Canadian infrastructure processes or the American infrastructure processes. At the point at which the agreement came into place, all of a sudden those numbers would change in any event. Anybody who has been involved in the real world, as I have been, knows there is a contract that you let, but when you let a contract for a project, that's just a top-line number. Most subcontractors have not been engaged, so even though it may appear that the contract has gone out the door, it hasn't; the bulk of the contract is still available through subcontracts.
If anybody could ever pretend to be able to give you an accurate estimate of what would be available, they would just be making it up.
