How would proportional representation have shaped this election’s results?

The Conservatives could have gained more seats and could even have won the election if Justin Trudeau had enacted his 2015 promise of electoral reform. How would it have affected Monday’s results? We did the calculations. By Mélanie Meloche-Holubowskiand Naël ShiabOct. 23, 2019MethodologyWe used the results of the 2019 general election (last update: Oct. 22 at 6:10 a.m. ET) and kept only the parties with more than 0.3 per cent of the popular vote, which corresponds to one seat in a proportional voting system. For the purposes of this simulation, we excluded independent MP Jody Wilson-Raybould.
We drew on the 2016 report of the House of Commons Special Committee on Electoral Reform, which recommends that two-thirds of MPs be directly elected to constituencies and one-third be elected from party lists. These proportions would therefore correspond to 226 riding seats and 112 list (or compensatory) seats. However, our calculations are an approximation. We must consider the fact that with a different voting system, party strategies and voter behavior would likely differ.Mélanie Meloche-Holubowski — reporter; Nael Shiab — data journalist; Melanie Julien — desk editor; Francis Lamontagne — designer.
