"Faced with the question of whether Québec could make a unilateral declaration of independence, the Supreme Courthas  declared unanimously  that such a declaration would be unconstitutional both by Canadian constitutional law and international law. A constitutional amendment would, however, make such a secession possible. The Court added that Québec could hold a referendum of secession and, given a clear question and a clear majority in favour of secession, the rest of Canada, in such a case, would be constitutionally obliged to negotiate the terms by which Québec would accede to independence, and that such a secession must conform to important basic principles, namely, the rule of law, federalism, the protection of minorities and democracy".

Listen to your highest Court, bro.  And listen ass well to the British sense of fair play : 50 % + 1 vote, in the case of Scotland.
