Section 21(1)( a) of the Nuclear Safety and Control Act (NSCA) empowers the CNSC to enter into arrangements with any regulatory agency or department of a government or any international agency. At the domestic level, these arrangements include administrative arrangements (AA), letters of agreement (LOA), letters of understanding (LOU), memoranda of agreement (MOA), and memoranda of understanding (MOU). These arrangements (which are often MOUs) provide a framework for bilateral cooperation, and provide the participants with assurances regarding the security of information exchanged, as well as enhanced clarity about responsibilities regarding visits and costs related to cooperation initiatives, among other benefits. While these arrangements are not legally binding, they nonetheless represent serious political commitments.
