Thank you very much, Madam Chair.
Really, I must thank the witnesses this morning, because you are bringing a degree of subtlety to an area in which too often, especially after events of 9/11, and terrorism on our continent, it's been very easy to invoke fear and to invoke issues of national security to effectively take away individuals' rights, let alone to get into projects of questionable cost and effectiveness.
The reason we've called you here is to learn more about the use of the national security exception in other countries and how we can improve that application here, particularly in regard to IT services, to Shared Services.
For you, Mr. Cox, how does Canada compare to our Five Eyes allies in the use of exemptions with IT infrastructure, which admittedly is a whole new territory? We're not talking about weapons and so on, but it can be just as effective a weapon.
