What is overwhelming Canada’s culture is massive 3rd world immigration. Just to cover the real elephant in the room.
Just search "Indians dumping trash in Canada" and you'll get an endless stream of videos of Indian immigrants doing their damnedest to make Canada look as trash strewn as India.
It's genuinely astonishing.
The transformation of Canada was dictated by the irreplacable genetic losses it suffered from 1914-1945. Canada’ loss of its best men during over ten years of savage war reflected a high percentage of its most productive citizens. A higher percentage and more devastating considering its smaller population. Immigration from the third world further altered the cultural fabric. Much of the same has happened in Britain. America is dealing with “allies” and neighbors that are not recognizable. So is their politics.
