There are probably an endless number of possible ways of designing it. The mixed member proportional has good features. It might be possible to design a made-in-Canada one that's not exactly the same as any of those, and not exactly the same as what anybody does in any other country, but has similar ideas.
To me, the key thing is, when you look down at the legislature from the gallery, does that roughly reflect how the people in the province, or in this case in the country, voted in the election? I think an outcome that comes closer to capturing that is progress.
I do agree that there would be very significant communication responsibilities associated with the change, to make sure people understand, as best they can, how the new system would work so that when they cast their vote, it can be as informed a vote as possible.
