It's a made-in-Canada model. To represent unrepresented voters the Law Commission, unlike the German model, did not recommend 50% "top-up" MPs. It had only 33% "top-up" MPs added to the local MPs, so local ridings don't have to double in size. Unlike the models which failed to win support in referendums in Ontario and P.E.I, it had open lists, not closed lists, so every MP faced the voters. In Ontario it did not have the province-wide lists which Ontario voters did not support in the referendum, but instead, the "top-up" MPs were to be elected regionally. Since the number of MPs from each province would not change, no constitutional amendment is required.
The full Report, all 209 pages, is on-line here. It has an eight-page executive summary. Here are the highlights:
. . . the Commission’s goal was to balance the benefits of introducing some element of proportionality into the existing system with the capacity to maintain accountable government, most notably as a direct link between elected politicians and their constituents. The Report, therefore, examines alternative systems from the premise that constituencies should stay small enough to maintain the Member of Parliament–constituent relationship. The Report also accepted the premise that there is little appetite for substantially increasing the size of the House of Commons to accommodate a new electoral system. Finally, the report is based on the premise that changes to the electoral system should be made without a process of constitutional amendment.
The conclusion of this survey is that adding an element of proportionality to Canada’s electoral system, as inspired by the system currently used in Scotland, would be the most appropriate model for adoption. Its potential benefits include:
• reducing the discrepancy between a party’s share of the seats in the House of Commons and its share of the votes;
• including in the House of Commons new and previously under-represented voices, such as smaller political parties;
• electing a greater number of minority group and women candidates;
• encouraging inter-party cooperation through coalition governments;
• reducing the huge disparities in the value of votes that currently exist, in which a vote for the winning party is often three to four times more “valuable” than a vote for any of the other parties;
• reducing the number of disregarded votes, thus increasing the number of “sincere,” as opposed to strategic, votes; and
• producing more regionally balanced party caucuses.
The Commission, therefore, recommends adding an element of proportionality to Canada’s electoral system, and that Canada adopt a mixed member proportional electoral system.
. . . democracy is more than just voting in a municipal, provincial, or federal election. Democracy is also about what happens between elections, how politicians and the electorate relate to each other, and the role that citizens play in their system of democratic governance.Highlights of their recommended model are:
How might the process of reform unfold? Drawing on the results of its consultation process, and the experiences of other Canadian jurisdictions, as well as the experiences of other countries, the Report concludes that it is crucial that citizens be included in an ongoing dialogue about electoral reform, and that the process of reform include a citizens’ engagement strategy. Many Canadians are eager to participate in democratic governance, and they need and want information. This strategy should have diverse and broad representation, including representation from women, youth, minority groups, and all regions. It should seek the views of political parties (minority parties as well as mainstream parties), Parliamentarians, and citizens’ groups. Any reform process should also include provision for formal review after implementing changes.
Adding an element of proportionality to Canada’s electoral system, as inspired by the systems currently used in Scotland and Wales, would be the most appropriate model for adoption."Recent Canadian research contends that turnout is 5 to 6 points higher in countries where the electoral system is proportional or mixed compensatory" says the Report. To quote the Jenkins Commission in the UK on “safe seats,” ”many voters pass their entire adult lives without any realistic hope of influencing a result. In these circumstances it is perhaps remarkable that general election turnouts remain at a respectable level.” In Canada, they have dropped well below a respectable level.
A mixed member proportional system should be based on giving voters TWO votes: one for a constituency representative and one for a party list. The party vote should determine who is to be elected from provincial and territorial lists as drawn up by the parties before the election.
Two-thirds of the members of the House of Commons should be elected in constituency races using the first-past-the-post method, and the remaining one-third should be elected from provincial or territorial party lists.
Within the context of a mixed member proportional system, Parliament should adopt a flexible list system that provides voters with the option of either endorsing the party “slate” or “ticket,” or of indicating a preference for a candidate within the list.
The federal government should prepare draft legislation on a mixed member proportional electoral system as proposed in this Report. After drafting the legislation, a Parliamentary committee should initiate a public consultation process on the proposed new electoral system.
An ad hoc Parliamentary committee should review the new electoral system after three general elections have been conducted under the new electoral rules.
The Report says it is inspired by the systems currently used in Scotland and Wales, which have 16-MP regions (9 local MPs, 7 regional MPs) or 12-MP regions (8 local MPs, 4 regional MPs). In Canada, with 2/3 local MPs, a 14-MP region would have 9 local MPs and 5 regional MPs. With the present 308 MPs, this would mean seven regions in Ontario, five or six in Quebec, two in BC, and two in Alberta. (With more MPs in 2015, BC and Alberta might well have three regions each.) The report also includes a sample "demonstration model" with larger regions, because they make it easier to show the smallest parties winning seats. But the point is, this "demonstration model" is NOT part of their recomendation.
The flexible open list method was also recommended by the Jenkins Commission in the UK. Their colourful explanation accurately predicted why closed lists would be rejected in Canada: additional members locally anchored are “more easily assimilable into the political culture and indeed the Parliamentary system than would be a flock of unattached birds clouding the sky and wheeling under central party directions.”
The process used by the Law Commission to prepare this Report included issuing a Discussion Paper and holding 15 public hearings, mounting an internet questionnaire, and holding more than 30 other meetings.
Should independent candidates be able to run for regional MP? The Commission is silent. Scotland, their inspiration, does allow this. On a related point, some democrats strongly believe that, if an MP is elected as a party candidate (even as a local MP), he or she should resign if they wish to cross the floor, and seek re-election as an independent or for their new party in a by-election. The Commission is silent about that too. So these are separate issues, not part of the design of an MMP system.
