A simple 50 percent plus one majority would be enough for Alberta to leave.

Summary
The Supreme Court's 1998 Secession Reference said democracy means more than simple majority rule and that a clear majority on a clear question is needed to create even a duty to negotiate. The Clarity Act puts this into law and gives the House of Commons the job of judging whether a majority is clear, weighing the size of the win and turnout, which implies more than a bare 50 percent plus one. Framing a razor-thin majority as automatically sufficient overstates the law.
Evidence
The Clarity Act says a clear majority is required and tasks the House of Commons with assessing it qualitatively, considering the size of the majority and voter turnout.
The Supreme Court declined to set a number but said a clear majority on a clear question, not bare majority rule, is what triggers a duty to negotiate.
