When there was an election in Norway last year, I was struck by the Norwegian electoral system, which features significant rural malapportionment built in and an interesting county-based apportionment system. In general I am interested in ways that proportional representation systems try to provide geographic representation, and it struck me that the Norwegian system would not be workable in most places but might be interesting in Canada. I also wanted to see if I could actually figure out the math based on the online English-language descriptions of the Norwegian electoral system, so I decided to apply that system to the most recent Canadian election. For simplicity's sake, this exercise presumes that there were six available lists (Liberal, Conservative, New Democratic, Bloc, Green, People's) and ignores all votes for other parties and independents. This should not make a difference in the results. Canada's ten provinces are treated as equivalent to Norway's nineteen counties. There are 150 regular seats (like in Norway) and one leveling seat for each province, resulting in a final count of 160 seats compared to Norway's 169. Because of the Norwegian principle of apportioning seats based on land as well as population, treating the territories equivalently to provinces would make this exercise farcical, so their votes are not counted as part of every province but are counted in the nationwide total. The results are identical to the results if territorial votes were excluded entirely. We begin with apportionment. In Norway, seats (aside from the leveling seat for each county) are apportioned by county based on a formula of population plus 1.8 times square kilometers. Prince Edward Island would qualify for no seats under this formula, so the island is assigned one seat and the rest are apportioned. Province | Population | Land area in km² | Formula | Seats | Population per seat | Ontario | 13,448,495 | 1,076,395 | 15,386,006 | 50 | 268,970 | Quebec | 8,575,779 | 1,542,056 | 11,351,479 | 37 | 231,778 | British Columbia | 4,648,055 | 944,735 | 6,348,578 | 20 | 232,403 | Alberta | 4,067,175 | 661,848 | 5,258,501 | 17 | 239,246 | Manitoba | 1,278,365 | 647,797 | 2,444,399 | 8 | 159,796 | Saskatchewan | 1,098,355 | 651,900 | 2,271,775 | 7 | 156,908 | Newfoundland and Labrador | 519,720 | 405,212 | 1,249,101 | 4 | 129,930 | Nova Scotia | 923,595 | 55,283 | 1,023,104 | 3 | 307,865 | New Brunswick | 747,105 | 72,908 | 878,339 | 3 | 249,035 | Prince Edward Island | 142,910 | 5,660 | 153,098 | 1 | 142,910 |
Next, the 150 ordinary seats are apportioned in each province by the modified Sainte-Laguë method. I will leave out the details here, since they are not interesting. Province | Lib | Con | NDP | BQ | Grn | PPC | Total | Alberta | 3 | 10 | 3 | 0 | 0 | 1 | 17 | British Columbia | 5 | 7 | 6 | 0 | 1 | 1 | 20 | Manitoba | 2 | 4 | 2 | 0 | 0 | 0 | 8 | New Brunswick | 2 | 1 | 0 | 0 | 0 | 0 | 3 | Newfoundland and Labrador | 2 | 1 | 1 | 0 | 0 | 0 | 4 | Nova Scotia | 1 | 1 | 1 | 0 | 0 | 0 | 3 | Ontario | 20 | 17 | 9 | 0 | 1 | 3 | 50 | Prince Edward Island | 1 | 0 | 0 | 0 | 0 | 0 | 1 | Quebec | 13 | 7 | 4 | 12 | 0 | 1 | 37 | Saskatchewan | 1 | 4 | 2 | 0 | 0 | 0 | 7 | Total | 50 | 52 | 28 | 12 | 2 | 6 | 150 |
Now we get to the fun part, the leveling seats to ensure nationwide proportionality (and thereby counteract malapportionment, at least in terms of national results). To qualify for leveling seats, a party needs to receive at least 4% nationally. Party | Votes | Percentage | Conservative | 5,739,099 | 34.08% | Liberal | 5,542,193 | 32.91% | New Democratic | 3,024,009 | 17.96% | Bloc Québécois | 1,301,615 | 7.73% | People's | 837,578 | 4.97% | Green | 395,814 | 2.35% |
The Green Party falls below the threshold. The two Green seats won at the constituency level are thus excluded, and instead of apportioning the full 160-seat legislature by party we instead apportion 158 seats. Party | Total seats | Constituency | Leveling | Conservative | 55 | 52 | 3 | Liberal | 50 | 53 | 3 | New Democratic | 28 | 29 | 1 | Bloc Québécois | 12 | 13 | 1 | People's | 6 | 8 | 2 |
Unfortunately, the Bloc being entitled to just one leveling seat means we miss out on the amusing scenario whereby a the leveling seat from a province other than Quebec is assigned to the Bloc. Again I will omit the calculations here, but I will note that the large number of seats relative to population in Newfoundland and Labrador and Prince Edward Island result in those provinces having few wasted votes, which means in turn that their leveling seats are not assigned to the end. In this case that means that the People's Party wins a leveling seat in both provinces on about 3%. If there had been an extra Bloc seat, it would have been here. Province | Lib | Con | NDP | BQ | Grn | PPC | Total | Leveling | Alberta | 3 | 10 | 3 | 0 | 0 | 1 | 17 | NDP | British Columbia | 5 | 7 | 6 | 0 | 1 | 1 | 20 | Lib | Manitoba | 2 | 4 | 2 | 0 | 0 | 0 | 8 | Lib | New Brunswick | 2 | 1 | 0 | 0 | 0 | 0 | 3 | Con | Newfoundland and Labrador | 2 | 1 | 1 | 0 | 0 | 0 | 4 | PPC | Nova Scotia | 1 | 1 | 1 | 0 | 0 | 0 | 3 | Lib | Ontario | 20 | 17 | 9 | 0 | 1 | 3 | 50 | Con | Prince Edward Island | 1 | 0 | 0 | 0 | 0 | 0 | 1 | PPC | Quebec | 13 | 7 | 4 | 12 | 0 | 1 | 37 | BQ | Saskatchewan | 1 | 4 | 2 | 0 | 0 | 0 | 7 | Con | Constituency | 50 | 52 | 28 | 12 | 2 | 6 | 150 | Leveling | 3 | 3 | 1 | 1 | 0 | 2 | 10 | Total | 53 | 55 | 29 | 13 | 2 | 8 | 160 |
Presented differently: Party | Votes | Percentage | Seats | Percentage | Conservative | 5,739,099 | 34.1% | 55 | 34.4% | Liberal | 5,542,193 | 32.9% | 53 | 33.1% | New Democratic | 3,024,009 | 18.0% | 29 | 18.1% | Bloc Québécois | 1,301,615 | 7.7% | 13 | 8.1% | People's | 837,578 | 5.0% | 8 | 5.0% | Green | 395,814 | 2.4% | 2 | 1.3% |
The results here are basically proportional after accounting for the Green vote is underrepresented due to failure to break the threshold. The Bloc overrepresentation is significant compared to the size of the Bloc vote. Any two of the three largest parties can achieve a majority together, while the other three parties are irrelevant to that process. What is the takeaway from this? Nothing, really, but I did the work so I thought I'd share it. As a bonus to those of you who made it this far, here's 1993: Province | Lib | Ref | PC | BQ | NDP | Nat | Total | Leveling | Alberta | 4 | 9 | 2 | 0 | 0 | 0 | 15 | PC | British Columbia | 6 | 7 | 3 | 0 | 3 | 1 | 20 | NDP | Manitoba | 4 | 2 | 1 | 0 | 2 | 0 | 9 | Lib | New Brunswick | 2 | 0 | 1 | 0 | 0 | 0 | 3 | Lib | Newfoundland | 4 | 0 | 1 | 0 | 0 | 0 | 5 | PC | Nova Scotia | 3 | 0 | 1 | 0 | 0 | 0 | 4 | Ref | Ontario | 26 | 10 | 8 | 0 | 3 | 0 | 47 | PC | Prince Edward Island | 1 | 0 | 0 | 0 | 0 | 0 | 1 | BQ | Quebec | 13 | 0 | 5 | 20 | 0 | 0 | 38 | PC | Saskatchewan | 3 | 2 | 1 | 0 | 2 | 0 | 8 | BQ | Constituency | 66 | 30 | 23 | 20 | 10 | 1 | 150 | Leveling | 2 | 1 | 4 | 2 | 1 | 0 | 10 | Total | 68 | 31 | 27 | 22 | 11 | 1 | 160 |
Notably, neither of the Bloc leveling seats are in Quebec. Party | Votes | Percentage | Seats | Percentage | Liberal | 5,647,952 | 41.3% | 68 | 42.5% | Reform | 2,559,245 | 18.7% | 31 | 19.4% | Progressive Conservative | 2,186,422 | 16.0% | 27 | 16.9% | Bloc Québécois | 1,846,024 | 13.5% | 22 | 13.8% | New Democratic | 939,575 | 6.9% | 11 | 6.9% | National | 187,251 | 1.4% | 1 | 0.6% |
