So because Quebec ancestors killed all the people who opposed the conquest of that land, it's okay for Quebec to secede? But because another set of Canadians didn't kill off all the natives that still claimed Alberta's land, they can't secede legally? Is that the logic?

Wow, I'm not sure where you're going with that. Read up on the ''Brandy Parlit'' debates and you'll see that genocide of indigenous people was never at play in early Quebec. The relationship between European colonists in New France/Lower Canada/Quebec and First Nations has always been frought, but not genocidal.
