In Canadian elections over last 50 years, different percentages of voter support yielded the same number of MPs in the House of Commons. And the same percent of voter support yielded varying numbers of MPs in the House of Commons. Small parties never got their fair share of seats, often getting zero seats. The leading party usually received 10 to 25 percent higher percent of seats than its vote share. Here's digest of the varying results in each bracket. 2 to 4 percent of votes == percent of seats range is zero to less than 1 percent (.6) 5 to 9 percent of votes == percent of seats range is 0 to 4 percent (leaving aside the BQ results) 10 to 14 percent votes just one example == seat percent 4 percent (leaving aside BQ results) 15 to 19 percent of votes == percent of seats range is 6 to 12 percent 20 to 29 percent of votes == percent of seats range is 13 to 25 percent 30 to 34 percent of votes == percent of seats range is 29 to 47 35 to 39 percent of votes == percent of seats range is 40 to 54 40 to 49.7 percent of votes == percent of seats range is 52 to 75 in last 23 years, in Canadian federal elections, parties have received widely varying vote-percent to seat-percent ratios. In the list below, the almost random results can be seen by the parties being arranged according to vote share growing progressively larger while the respective seat share bounces around. =============================== Here is list of party election results, from least popular to most popular, showing that at each level parties receive widely varying number of MPs. (where a bracket has multiple examples, that is.) all major parties of last 23 years are shown here. also shown are leading parties' totals for last 50 years. parties with less than 2 percent vote share not listed here. 2 to 4 percent of votes == percent of seats range is zero to less than 1 (.6) percent 2021 opposition Greens 2 percent of votes less than one percent of seats (.6 percent) 2/338 2019 People's Party 2 percent of votes 0 seats 0/338 2015 Greens 3 percent of votes less than one percent of seats (.3 percent) 1/338 2011 Greens 4 percent of votes less than one percent of seats (.3 percent) 1/308 5 to 9 percent of votes == percent of seats range is 0 to 4 (leaving aside the BQ results) 2021 opposition People's Party 5 percent of votes 0 seats 0/338 2015 opposition BQ 5 percent of votes 3 percent of seats 10/338 2011 BQ (regional party) 6 percent of votes 1 percent of seats 4/308

A certain amount of vote share goes in and and there is almost no telling how many seats a party will win. Food for thought... Happy New Year - may it be at least better than the last one!

SOURCES OF INFORMATION ON CANADIAN FEDERAL ELECTIONS
Here is an update following our conversation last year.
Appendix 1: Evolution of the Federal Electoral System in The Electoral System of Canada will be reviewed and revised to correct the error you brought to our attention.
The other article we discussed – the article about Agnes Macphail – was published in a magazine called Electoral Insight. The magazine ceased publication in 2006 and will be removed from our website as part of a larger project we are working on to update our web content.
Thanks, again, for taking the time to contact us about the errors and for your patience as we address them.
And, in case you’re interested, here are some of Elections Canada’s resources on the history of voting rights in Canada that I find useful:
A History of the Vote in Canada (2021, third edition)
