I disagree, Vincent... The Supreme Court of Canada, in
Reference re Secession of Quebec, [1998] 2 S.C.R. 217 clearly stated that Quebec has no unilateral right to secede. That being said, of course Quebec has it's own unique culture... but so does Newfoundland. So does Nova Scotia and British Columbia - every province is different from the others, some more than others. It's the same with the First Nations as well. That's the strength of the Canadian federation - we can take all these diverse strands from all over the world and weave them together... but instead of becoming a "melting pot" and having them meld into a new society, each preserves it's own identity within the common framework.
Quebec is the cornerstone of the Canadian federation - they're what the country was built on... a Canada without Quebec is as meaningless a concept as a Quebec without Canada - neither can exist apart from the other. It's akin to the South within the US - without it there, the country is meaningless.
Sovereigntists come and go... whether it's Lévesque or Parizeau or Bouchard, they each come and strut their time on the stage and wave the
Fleurs-de-Lis and whip up Quebec nationalism, but they all end up crushed and defeated by the Canadian reality. Quebec will never separate - sovereignty is just a hopelessly romantic dream held by a misguided few.
