What the Supreme Court’s Reference re Secession (1998) actually says

Takeaways:

• Provinces have no constitutional right to secede from Confederation.
• Referendums have no legal significance within Canada’s constitutional framework.
• Positions taken by governments during constitutional negotiations are not subject to judicial review. 

Reference re Secession drops anchor in paragraph 84:

84. The secession of a province from Canada must be considered, in legal terms, to require an amendment to the Constitution, which perforce requires negotiation. The amendments necessary to achieve a secession could be radical and extensive. Some commentators have suggested that secession could be a change of such a magnitude that it could not be considered to be merely an amendment to the Constitution. We are not persuaded by this contention.  …The fact that those changes would be profound, or that they would purport to have a significance with respect to international law, does not negate their nature as amendments to the Constitution of Canada.
