I would think that Canada, Australia, and the UK will all diverge culturally and socially in 100 years. They'll still have that commonwealth history and heritage of course, but that will get further and further in the past.

Canada is going to always be close to the USA, nobody is going to manipulate a lightly populated nation that speaks the same language and shares the same culture as a land-border neighbor of a by then 400-million strong nuclear armed world power that will still be swinging its dick around. Australia is highly vulnerable to Chinese geopolitical influence and will probably become very Asian in a demographic sense, maybe even drifting towards being like a big Singapore with white people sometime in the distant future. The UK will always its own proud self of course, and maybe drift closer to the US as well after Brexit.
