I don't have much to add to that, except to note that there is a provision in both the convention and Bill C-6 that would prevent a Canadian in that position from expressly requesting the use of cluster munitions, should the choice of munitions used be within the exclusive control of the Canadian armed forces. The circumstances that may arise, and would more often arise, in a multinational operation would be that Canada would not have exclusive control over the choice of munitions used by other states because their choice of munitions is made as a sovereign decision of theirs, and they are participating in that operation as an ally.
So there are certainly circumstances where, if a Canadian had exclusive control over these, he or she would be prohibited from it, and Canadians would be prohibited themselves from using cluster munitions in any event because those are policy decisions clearly within the exclusive control of Canada.
