The Clarity Act empowers the House of Commons, with the Prime Minister's office largely in charge, to decide whether the secession referendum question is "clear", whether the result reflects a "clear majority", whether negotiations may begin, who gets to weigh in at each stage, and whether separation terms are resolved.
All while providing no path to provincial independence.
In short, even a decisive "Yes" vote may not be enough to leave. Ottawa calls the shots, while the province trying to separate gets no say.
