Sir, that's one of the principles Canada has always acted by. I would suggest that ratifying the two instruments affected by Bill S-9 is an important step towards reaffirming our commitment to be 100% compliant with the international system.
As to the physical protection, I want to stress that all those aspects have been in place since 2006, and some aspects were in place before that.
As for the comment about being one of the items considered by the Nuclear Security Summit in securing vulnerable material, in no way would the HEU and other material in Canada be considered vulnerable in comparison to established international norms for the protection of such material.
