Mr. Speaker, recently there has been a bit of media attention to one aspect of this and that is the security service itself, the number of people involved in providing the screening service. I do not profess to be an expert at all on whether that's being handled adequately or not, but as the requirement for security is established and rolls out, I would like to ask the Minister is there any ongoing assessment of the costs of providing this service and is there any provision for potentially making adjustments that could be cost saving in providing this very valuable service, Mr. Speaker?
