Deliberation takes time, especially since, as we've mentioned earlier, people don't know about other systems. The best answer is to have more flexibility to abandon the deadline, which was an early promise made, I'd argue, without a lot of thought about what the consequences might be. The committee in some ways is a little behind the curve in terms of setting things up and getting things going. Here we are in 2016, and we're still at the stage of working out the alternatives.
My ideal would be to delay the 2019 deadline and say that there has to be a proper process. This isn't the sort of thing that you can do fast and get it right, and you want to get the outcome right. These are also windows of opportunity. They open up now and then for you to change the system, and they don't change necessarily in 10 or 20 years, so you want to make sure that the decision reflects the Canadian public and what people would like and what Parliament would like.
Delay is better than to try to rush to an artificial deadline.
