Declining voter participation, strategic-voting campaigns, public opinion polls, and myriad other signals highlight the need to improve Canada's current first-past-the-post electoral system. How the system ought to be changed, however, remains unclear. This paper briefly reviews candidate models for electoral reform from other nations, before putting forward the parsimonious mixed-member (PMM) model. This model was inspired by the mixed-member (MM) proportional representation system, as currently used in, for example, Germany. It is 'parsimonious', however, in the sense that the number of additional MPs brought into parliament to reach proportionality is minimized. Like traditional MM, PMM preserves the individual relationship between every voter and an MP, and it eliminates under-representation of parties. Unlike traditional MM, however, it also preserves the incentive for parties to win local races, it avoids unnecessary dilution of constituency representatives, and it avoids misattributing spoiled ballots to major parties. As such, it can be thought of as an optimization of MM. A key feature of this model is conservatism -it modifies our existing system with the minimal set of changes necessary to resolve the most obvious problems in the current system, without creating new ones. It fixes only what is broken.
