National referendums, yes.
Constructing an argument that it is a requirement somehow of a major change is a bit of a stretch for me. Whether it's a good idea along the line you were suggesting to build legitimacy, that's a normative question. We could probably kick that back and forth. I think building legitimacy is certainly one of the criteria that's been mentioned in the committee documents, and a referendum could be a tool to build legitimacy, but you have to think about how to use it, how to make it do that, because there's nothing in referendums inherently that automatically makes them do that.
Citizens' assemblies, of course, have been the tool chosen in a couple of the provinces. I was very close to the Ontario citizens' assembly. I thought it did a terrific job in terms of deliberating the issue. It was really inspiring for a student of democracy like me to see 102 people in a room, who came in knowing almost nothing about this topic, often with some preconceptions or misconceptions about it, and watch them build consensus.
