I will let my colleague, Mr. Mayers, give you some specific examples of regulatory co-operation between Canada and the U.S.
Even though we have different legal systems, we certainly share regulatory objectives and outcomes that are very similar on a number of elements. Given the closeness between our two countries, it's natural for us to co-operate very closely with the U.S. Clearly, with the volume of trade that flows between the two countries, issues can always arise. However, in most cases, if not the vast majority, things run fairly smoothly. Mr. Mayers can give you some examples of that.
