I think that with the adoption of any new system there's going to have to be a process of education. Elections Canada will have to play a leading role in that to accustom them to the new system. Also, elected members and people running for office will have to inform their party members and their substantial supporters of how things work.
I think that, over time, people will see the truth of the system. If you end up recommending a system that emphasizes party control, then they'll see that. If you don't, then they will see that there's not necessarily any greater level of party control under a PR system than under first past the post. It really depends on the particular system that you choose.
