The problem with integrating votes is that votes are lost. Plurality discards votes whereas other voting systems do not. One voting system that I like very much is approval voting, which is really very simple. People are not forced to vote for one candidate only. I am not suggesting forming a Parliament in that way, but it could be appropriate for byelections in the Yukon, the Northwest Territories and Nunavut. In those places, strategic voting tends to disappear into thin air. People vote for the candidate they like the most. The one with the most votes really is the one supported by the greatest number of people. For the mathematicians amongst us, it would not necessarily be the Condorcet winner. Nevertheless, with plurality, the margin of error is frightening, between 20% and 30%.
There are other methods. The N-round system is a little better. The margin of error is from 10% to 15%. If you want a voting system that really determines the local winner, and makes sure that it is the right one, it might still be fine. However, I know that, by so doing—and Raymond Côté is going to propose something along those lines in a moment—you end up with centrist parties. You eliminate some options. It is always a matter of choice. You either want some diversity in Parliament or you want people in the centre. There are two types of voting systems, depending on what you want the result to be.
