I'm glad someone asked me about a referendum.
The best way to ensure legitimacy is for you to home in on recommendations that will demonstrate how the narrow focus of your question improves the broader governance question. Put that to the Canadians you're consulting with and discussing these matters with, make that open and transparent—which, of course, by virtue of these committee meetings it is—and that will draw everybody in the country to conclusions about where this should be heading. If it takes more than one round of these committee meetings over the course of a life of any Parliament, so be it. That is the hard work of governing.
On the issue of referenda, if I have a moment...or will I pick it up in another question?
