Civil War, in a US 1812 victory?

After a US victory in the War of 1812, where the United States annexed the remainder of British North America (Assume Britain was to distracted by Napoleon and underestemated the US). How would the Civil War go, assuming that one still takes place as the US works to abolish slavery? Would the "Canadian" states follow the same trend as the OTL Northern States and be among the first to abolish slavery?

So, following the civil war, how do the Canadians change things? How does the US evolve after the war? How dose industrialization take place? Would there ever be a Canadian President?
 
Could see a Canadian Rebellion and British Invasion (if things continue OTL a French one as well)

Good Luck USA

The whole thing? In that case, probably an earlier Civil War, preceded by maybe an earlier Mexican-American War (with more gained) and probably no Missouri Compromise, despite the far north states not being able to be numerous enough to pose very much more of a threat to the south. Oh, and early Cuba, of course.

What, it’d wind up being… maybe five more free states by roughly the ‘50s? So maybe Texas’ land is split between two or three states, plus Cuba, Kansas might go slave…

Anyway, earlier Civil War.

Probably but it's not certain. Canada is definitely going to come in as several free states and it's possible that they would push the slavery issue in Congress as you said. But the South was a lot less reliant on slavery in the early 1800's than it was by 1860. The cotton gin had only just been invented and even in 1830 the number of slaves was relatively low and there was nowhere near the economic impact that it had in 1860. A gradual emancipation like Pennsylvania did is more likely the earlier the issue is raised although the odds of that decrease every year that it continues.

Within a generation the Tories are going to be swamped by immigrants from Europe and settlers from other parts of America. That won't be a factor after they're assimilated.
 
Two challenges

Two key questions that I posed (p. 165) on this alternate outcome:


  • (a) How would/could elites in Washington regulate the entry of slave and non-slave states into the Union, i.e. the conscious balancing of the Missouri Compromise of 1820 vs. popular sovereignty of the Kansas-Nebraska Act of 1854. Do the comparatively lightly populated Upper, Lower, and Maritime Canadas become three states that are fairly easily absorbed?

  • (b) How would/could the largely Protestant US absorb largely Catholic Lower Canada (Quebec).
 
Wouldn't most of Canada be likelier to remain as territories first, until it was filled up with a sufficiently high population of loyal US citizens, with new states being added piecemeal? That was how the United States dealt with adding more territory IOTL.

I'd imagine that there would be more slave states, since the North has a new, massive area to expand into and the South doesn't. With more land in the United States, there might also be more immigration from Europe, though I'm not sure about that point. How these would affect the timing of the American Civil War, I'm not sure.
