After a quick trawl through Wikipedia (I know, I know) and
Statistics Canada here's some pertinent information:
Population:
Estimates from Statistics Canada:
- New Brunswick (1806) - ~35,000
- Nova Scotia - est. 65,000 (1807), est. 81,351 (1817)
- Upper Canada - est. 70,718 (1806), est. 95,000 (1814)
- Lower Canada - est. 250,000 (1806), est. 335,000 (1814)
- Newfoundland - est. 26,505 (1806), est. 52,672 (1816)
- Prince Edward Island (1822) - est. 24,600
If we compare that to the
1810 US Census, then Nova Scotia, New Brunswick and both Upper and Lower Canada would easily qualify as states in their own right. (Don't forget, Upper and Lower Canada were formed in 1791, and Cape Breton Island was a separate colony between 1784 and 1820.)
Even looking at the
1820 US Census, Lower Canada wouldn't even make it into the top 10 most populated state (it would be 12th, coming between Georgia and Maine). Meanwhile, PEI would have a population smaller than that of Charleston.
Therefore, I propose the following:
- the US admits Nova Scotia as a state, capital Halifax. The colony of Cape Breton is merged back into Nova Scotia, due to its low population
- the US admits New Brunswick as a state, capital Fredericton. Prince Edward Island is merged into New Brunswick, due to its low population
- the US admits Upper Canada as the State of Ontario, capital York (OTL Toronto). However, it is possible that the US decides to shave off Northern Ontario as a territory, to be admitted later
- the US admits Lower Canada as the State of Canada, capital Quebec City
- assuming the US also annexes Newfoundland (capital St John's), it probably gets organised as a territory first, and admitted as a state later on, since that near doubling in population over ten years would easily push it over the threshold
