Obviously a heavy immigration policy impacts on a nation. In recent times, attention has been drawn to the rise of anti-semitism in Canada, a blight on any nation. Some have pointed out that this phenomenon has occurred alongside an increase in Islamic fundamentalism in Canada. Anti-Americanism also goes hand in hand with Islamic fundamentalism. Again this is endemic in Canada and in many other parts of the world - do I have to mention France? Immigration can no doubt change a nation, and not always for the best. All countries that are encouraging immigration need to look at the potential long-term effects. Unfortunately, political correctness has prevented this. The sooner the political correct accept the reality that not all cultures are compatible the better off everyone will be. How, for example, can you reconcile the position of women in Western culture with that of women in Islamic culture? What will happen to women if Islamic culture becomes the dominant culture? It is not the past we have to fear but the future.
Canada's immigration policy is very extreme non-assimilationist. So much so that new immigrants are felt that they are rebuilding replicas of their former home countries in Toronto, Vancouver, or Montreal.
Having said this, English Canada doesn't have much Muslim problems - yet. Most of the Islamic problems in Canada are confined to Islamic immigrants to Toronto. Presumably becasue there are still a relatively small number of Muslims in English Canada at this stage. In Vancouver and Toronto Chinese, Indians, and Jamacians seem to predominate.
So I don't think anti-Americanism in Canada is due to Muslims (as is the case in some Western Euroepan countries). The rot is already set among the native populations.
