I think there should be more on the Canadian aspect of critism of a proposed united currency As the article stands it is decidedly American in terms of the arguments against it In some quarters it seems that it is seen as a given that Canada and Mexico would leap at the chance to piggy back on the US dollar when for reasons such as you state that is not the case at all In fact there is a lot of resistance to the notion in Canada that we should join the US dollar or create an Amero type currency It IS more welcomed the concept in Quebec but I doubt most Canadians would favour the idea peso included or not
