Broadly we do, but there's obviously room for improvement. I think it's happening at the two levels. It's what we do nationally in terms of export controls and ensuring that they continue to be comprehensive.
A few years back some changes were made that allowed catch-all provisions to enable us to be more effective in enforcing controls. But we're in a very interdependent world and we have to cooperate in the multilateral area. Canada has been a member of the Nuclear Suppliers Group there, and that group is mostly about ensuring that there are guidelines to prevent transfer of nuclear technology to states that haven't submitted themselves to the IAEA safeguards regime. That cooperation continues to be perfected--the exchange of information, etc.
I think we have a pretty satisfactory approach, while recognizing that you have to be constantly vigilant and searching for improvements.
