It is more likely there would have been the 1 French nation of Louisiana and the separate American nations, A Bilingual nation of Quebec as well as the Indian nations to the West.
The large English population in modern Canada was due to the mass exodus of Loyalists fleeing the War of Independence. Canada up to that point was a few Colonies in the East and Quebec. If there was no war of Independence the Quebec act would have been in place halting Westward expansion and forcing a North South growth, in the hopes of assimilating the French population of Canada.
The Indian Nations to the west were protected by this.
California would likely have remained a Spanish colony or part of Mexico.
Louisiana would have remained a French Colony until the Napoleonic Wars would force the British to take it much as they did with Quebec in the 7 years War (French/Indian War)
The separate colonies would have no real impetus to join each other and so would each seek their own independence. Before 1865 the common phrase used describing the USA is The United states are (rather than is) showing the closer identification of the individual states rather than the country as a whole.
By the way Go Alien’s assertion that:
“The colonies would have developed more like Canada and Australia and been dependent on rather than independent of Britain"
Doesn’t quite ring true, (I can only speak for Canada but I have a feeling an Ausie will also take exception to that comment.)
When Canada became a Dominion in 1867 its economy was already closer to the United States than Britain. We also ceased to be dependant on Britain as far as Military aid and many industries already existed so we didn’t really need too many of your goods in exchange for our resources, thank you very much.
The only real dependence was Political. Only because it was written in the BNA act, our Superior court was the Privy Council, based in London. This until we finally dumped it did a fine job of mucking up our Federal system with their decisions in the late 1890s and into the 20th Century.
We have kept many of our ties with Britain (the Commonwealth, keeping the Queen as our Sovereign) but to Claim Canada was Dependant at the time of Confederation is bogus.
