In a piece discussing four upcoming by-elections, iPolitics’s Susan Delacourt mentioned in passing that “unless electoral reform happens really quickly, those seats will be filled the old-fashioned way — no preferential ballots, winner take all.”
Which made me wonder: how exactly would electoral reform deal with vacancies in Parliament? By-elections, after all, only work if MPs are elected from individual constituencies; you can’t run a campaign across an entire province or country just to fill one or two seats out of more than three hundred.
I could speculate, but instead I had a look at the website of Fair Vote Canada, a group advocating for proportional representation in Canada, to see what their solution would be. In their submission to the Special Parliamentary Committee on Electoral Reform, FVC proposed three options, one of which was mixed-member proportional representation, in which regional seats, elected from party lists, are added to MPs directly elected by their constitutencies. In that option, regional seat vacancies would be filled from party lists.
In case of a resignation or death of a regional MP during a term, the party’s runner-up moves up into the seat. No working MMP model has by-elections for regional MPs. As the Jenkins Commission pointed out, if a region-wide contest were to take place “it would almost by definition result in the victory of the predominant party in the area, thus negating the essential purpose of the Top-up seats.”
I have to say, this isn’t something that makes me more likely to support proportional representation.
