The subject has come up quite a bit in the hearings, both on the road and here in Ottawa. Some have said we should follow the New Zealand example of two referenda prior to a change and then one after the change to give approval or not to that change. Some have said, for example, that the 60% threshold in the B.C. referendum was arbitrary and too high, so some extent, yes, people have touched on the details, but it has revolved mostly around the principle of a referendum.
