It also needs the endorsement of Canadians. Look at what happened with Brexit. That is a country divided at the moment. Whatever system you put forward, you're going to have to find some way to check with citizens about whether this feels right or not. I don't know whether that's a formal referendum or not. I'm not trying to propose one way or the other. I do think you need test some system.
The challenge will be that if you get down to three or four different systems, and one of them maintains the local representation for ridings like the Yukon—I don't want to just say the Yukon, but “like” the Yukon—and then you put that into the mix and put it out there, it could easily lose against those other ones.
The thing I'm asking you not to rest on your laurels about, or not to be overly partisan on, is to watch that when you get down to those choices, you've done your best to try to maintain that local representation in all of the systems you propose.
