Do you mind if I take that, Mr. Chair, in that it's a program issue?
It is not often, to be quite honest, but it does happen. It happens on occasion. It has happened on a few occasions in Ottawa--for example, with HRSDC, Elections Canada, and CRA--but we try to mitigate as much risk as we can in those situations. At the same time, we put the departments on notice now that if they're changing their minds, this is the cost involved with changing their minds.
At the same time, because of a recommendation in one of the new requirements that came out from SCOPA, we will now report in our plans and priorities statement, in our departmental performance report, those groups that don't accept the lowest-cost solution, so that's very transparent now in the process.
