Canada passes IMHO. It does open questions that Googer and Aaron would need to find a way to retcon. Specifically why China wasn't involved, and why Spain let this happen. Because of that, I would suggest both Aaron and Googer should also approve before we move forward.

If you want to polish it up, I would suggest making the revolution less convenient. It just sort of seems to work out all the time. I do admit you'll see that in the previous histories, in part because this RP started with looser standards and because we've had to go back and retcon the histories in such a way that they could be accessible while still making sense. 

Slaughters are always a good impetus for revolution. The economy tanks, different groups rise out of the divide, the socialists take to the street in Quebec, the army/police/paramilitarists kill a bunch of people. Those in the middle condemn the aggressive right-wing attackers and the government is implicated one way or another. The only other thing you'd need to work out is why Spain isn't involved, but you could work that out with either.

Like I said at the beginning, I don't think this change is absolutely necessary and if it feels to uncomfortable to you than I would understand. What you have now works well enough. And of course, if you do want to update it you wouldn't have to follow the script.

Just remember that, for the most part, revolutions have a tendency to be somewhat ugly. It isn't a rule, but it's a common enough occurrence that we kind of expect it.
