That depends on how far you want to go.
What is unworkable is ending up with a reform that has been talked about since 1909, as is the case in Quebec. The best way of not achieving reform is to find all kinds of pretexts to slowdown the process. Once you have finished your work, I think you will have one thing left to do: to demonstrate that you are capable of reaching a compromise.
If each of you digs in your heels, you will merely have shown that compromises are very difficult to reach because the system is confrontational. If a majority of you is able, publicly or even in camera when you are deliberating, to choose a system based on the principles we discussed earlier and certain fundamental democratic values, I think that, surprisingly, you will be able to come to an agreement quickly. I think citizens would be happy and proud of that.
I support an independent Quebec and I would raise my hat to Mr. Trudeau if he were able, he and his troops, to make an alliance with the other parties to bring about real change. We need more than election promises: we need action on those promises and results. That will make people less cynical about politics and their elected officials.
