I think that you are misrepresenting most of what has been written here.
We are talking about transfer of administration in the early 1920s. At that time any european British citizen was automatically given same rights within Canada including ability to vote. Over the next 60+ years there would of naturally be a democratic and nationalistic movement of granting rights to all those who live within Canada. We did this with native Canadians in the territories.
By end of WW2 Canada would of done away with concept of colonies and organized these areas into territories. Some of these would eventually by 1960s become provinces. This of course would be subject to Canada 1) being interested in integrating said territories into the country 2) able to provide structure, investment snd integrate majority of the people living in those territories into Canada.
If you live in Canada you know the country has the capabilities and willingness to do so. If you don’t you just found out. Canada would be able and willing to invest snd develop such territories unlike Britain.
Now as for economics and increase in GDP. Bringing in Bermuda, South Georgia islands or Belize alone would not provide a noticeable increase in GDP to Canada but the inclusion of all British colonies in Western Hemisphere would increase Canadian GDP. What percentage I have to review these territories economy and determine also what increased economic activity they would have.
Hope this answer some of your disdain comments. Thanks.
No, it actually does not answer any of my points (and it outright ignores quite a few)
Canada is a country with a defined identity, they aren't just "british living in America" but their own distinct people (even if their identity is
related to the British one) and thus would not simply accept foreigners as part of their country, especially in the form of settler colonies from far away places when most of the country was (and still kinda is) unsettled. Nevermind that you are also applying a much more modern mindset when in truth the canadians of the time were as racist and xenophobic as everyone else. Maybe they would accept the mostly white settler colonies but places like Jamaica? Or quite a few other caribbean colonies? No way in hell they are given the same rights as continental canadian territory (or that they don't try to gain their independence before the proposed timeframe for the thread).
And what increased economic activity? Policing and protecting these territories would be a money sink and not something the population would like. Unless somehow the canadian population started buying into imperial ambitions (Big X for doubt here) the idea of "Let's have some former british colonies as our own!" would be answered with "Hmm, paying more taxes so the admiralty can have a few extra destroyers and maybe a carrier so we can keep some worthless souther territory that the UK gave us because they didn't want to deal with it? How about no." Because holy shit, why would anyone want such commitment when you are a small middling power happy to make your country good but with no real ambitions on the glabal stage? Most countries would
kill to be where Canada is today.
Of course the crux of the matter is that you haven't really answered any of my criticisms.
1) The AU nature of this divergence means that it wouldn't be just Canada which would be different, but everything else.
2) Canada would never, ever, waste the required money to maintain overseas possesions when not even the British were willing to.
3) The nature of nationalism means that most of the territories worth keeping would much rather become independent instead of being treated like shit or as second class citizens.
4) You have yet to explain how do they defend their ownership of it this time when "self determination" isn't an excuse (seriously, if the British pass the colonies like one does trading card then the whole "their identity and wishes matter" kinda takes a big hit).
Hope this answer some of your wankish assumptions of alternate history. Thanks.
Oh boy, a war between Galtieri's Argentina and Apartheid South Africa might be even more interesting.
It makes it really difficult to know who you want to root for, doesn't it? Both failling horribly seems like the best outcome.
