By the way, this is a pretty s hitty deal for Quebec if you're a separatist. They should have the right to continue to vote on these matters as long as there is a need. And it shouldn't be based on muddy terminology like "clear". If 51% decide to separate, then they move on to to the next step (whatever that is).
That's democracy - like it or not.
The problem with that is the ability of the separatists to take the question to the electorate over and over.....and over. The issue never goes away. The Neverendum, as some wag framed it.
It doesn't matter how often the federalists win, they never settle the issue, until the separatists win....once. As they almost did, and they cheated.
That is NOT democracy, and is why in every democratic country on earth that I am aware of, it requires a clear majority (often 2/3) to alter the constitutional makeup of the nation.
