LATEST NEWS: How DMP Could Work in British Columbia
Dual Member Proportional (more formally known as Dual-member Mixed Proportional) is a proportional electoral system that was created by Sean Graham in 2013 with funding from the University of Alberta. It was designed to meet Canada’s unique needs and to build support for proportional representation.
With DMP, Canada’s current single-member districts would be replaced with about half as many dual-member districts. All candidates would run in their local dual-member district, and voters would choose their preferred candidate or pair of candidates using a straightforward single-vote ballot. The first seat in every district would go to the local candidate with the most votes, while the second seat would be filled to create a proportional election outcome. Elected candidates would be responsible for representing their dual-member district and would rely on their local constituents’ votes for re-election.
DMP has many advantages over other proportional electoral systems. Some of the most noteworthy improvements are:
- Keeping the simple ballot design of Canada’s Single Member Plurality electoral system
- Eliminating the need for long party lists
- Retaining a higher degree of local representation and accountability
- Not increasing in complexity from the voter’s perspective as region size increases
- Reducing parties’ recruitment burden
- Satisfying the Senate clause when multiple provinces are included in one region

DMP and Federal Electoral Reform
On September 29, 2016, Sean Graham appeared as a witness before the Special Committee on Electoral Reform to present DMP. His submission to the Committee can be viewed on the Government page or by clicking here. To hear his testimony, listen to the audio clip below.
The PEI Plebiscite on Democratic Renewal
On November 7, 2016, the plebiscite on democratic renewal in PEI concluded. As a result of the recommendations made by the Special Committee on Democratic Renewal on April 15, 2016, DMP was one of the five options Islanders were able to choose from. The other four options were First-Past-The-Post (FPTP), First-Past-The-Post plus Leaders (FPTP+), Mixed Member Proportional (MMP), and Preferential Vote (PV).
According to the Interim Report of the Chief Electoral Officer, DMP received a significant level of support in this plebiscite. In the initial round of counting, DMP received nearly three times as many votes as FPTP+ and more than twice as many votes as PV. By the third round, DMP had taken 41% of the vote for change. The majority of the votes cast for DMP were then redistributed to MMP, pushing it over the edge to win the plebiscite. However, it is important to note that 26% of DMP’s supporters chose not to endorse MMP. This demonstrates that DMP was able to bring a significant number of people on board with reform that MMP could not.
Further evidence of DMP’s broad appeal can be found by looking at the distribution of the second choice preferences. DMP was the second choice of more voters than any other option. Moreover, DMP received more first and second choice votes than FPTP, suggesting that it has broader support than the current system.
