Thank you very much.
I'm in favour of STV precisely because of the Canadian context. If Canada wants to have a more proportional electoral system that changes as little as possible what we are familiar with and that is dear to us as voters and as the political class, which are set out in the five-point mandate, then for the reasons that I mentioned, this is the system that would come the closest, certainly closer than the other two.
The alternative vote is just not proportional. The MMP is too technical. This is the least complex system that introduces proportionality and still keeps those values intact. It's not my favourite system choice, but that's not relevant.
The mechanics of it, as far as the voter is concerned, are really quite simple. You are presented with a ballot, not unlike what we already have in any Canadian riding, except that you can rank order the candidates. Similar to the alternative vote, you are rank ordering the candidates in terms of your preferences.
Because there are multiple seats assigned to the district, political parties will be running multiple candidates. It is possible, as a matter of ballot design, to actually leave it up to political parties to determine how your preferences are going to be handled. That's an important detail that makes is easier for voters who may not be as informed about the choices to figure the system out. However, let's leave that complexity aside.
The system fundamentally works as such. You take a mathematical formula. It can be as simple as V over M plus one. The number of votes cast, divided by district magnitude plus one, which gives you a quota. That quota will essentially determine the threshold, the number of votes that will guarantee any candidate, any party, that gets that many votes from the electorate will be entitled to a seat. However, there will be surpluses and there will be candidates who are well beyond or below that threshold. Their preferences are going to be transferred in the order of the preferences that the voters themselves determine. The choice, fundamentally, in terms of who will be the beneficiary and who will benefit from these vote transfers, is automatically in the hands of the voter. It is proportional because of multi-member districts and because the quota I mentioned guarantees that.
Again, when you have many candidates running, and you have many candidates with a small percentage of the vote, those will still need to be transferred. That's why I said the administration of it can become time-consuming and complex. However, there are algorithms also now to work with that.
I want to stress that the system is not foolproof. If you follow current Australian debates about precisely looking at ways of changing the Australian system in place for the upper house, they are picking up on this issue. Therefore, the system is not foolproof, but given the mandate of the committee, it's still as close as it gets to meeting those principles.
