Over the past decade, an active debate has evolved in Canada about the desirability of electoral reform. While the issue is not new to Canadian academic interest, it took on greater currency following the 1993 election, which produced a highly distorted and regionalized Parliament.1 This distortion persisted to some extent in the two following elections, with the Liberals in 1997 forming a majority government with only 38.5% of the total vote and in 2000 with 41%. In all three instances, critics of our first-past-the-post (FPTP) electoral system called attention to some of the negative effects on Canadian democracy that seemed traceable to the electoral system – regional distortion, wasted votes, under-representation of the diversity of Canadian society, and declining competitiveness among Canadian political parties, to mention only a few.2 The electoral system may also be implicated in the declining voter turnout for recent elections, since Canadians may not be motivated to go to the polls if they feel that their votes do not really "count" under the current system.3 In early 2004, the Law Commission of Canada tabled its report on electoral reform, in which it recommended that Canada replace the current electoral system with a mixed-member proportional (MMP) system similar to that used in Germany and New Zealand.4 In making its recommendation, the Law Commission stated:
"... a growing number of Canadians are no longer satisfied with our current electoral system. It is becoming increasingly apparent that the current electoral system no longer responds to 21st century Canadian democratic values ... Many Canadians desire an electoral system that better reflects the society in which they live – one that includes a broader diversity of ideas and is more representative of Canadian society."5
The 2004 election results and the case for electoral reform
The recent federal election provides us with the opportunity to re-examine some of the elements of this debate with new evidence. On the surface, the result of the 2004 federal election was quite different from those of the previous three mentioned above. From the beginning, the 2004 contest was more competitive, the outcome remaining in doubt until the very end. The election produced a minority government, rather than a majority one – the Liberals' 37% of the popular vote translated into only 135 of the 308 parliamentary seats. Regional distortion appeared less extreme than previously, as the new Conservative Party won 24 seats in Ontario (in contrast to 2 won by the Canadian Alliance in the 2000 election), and the Liberals improved their representation in British Columbia (8 seats, compared to 5 in the 2000 election). The question thus arises: has the result of this election weakened the case for electoral reform? Is it possible that our electoral system performed better than expected in the recent election, and that some of the pressures to reform it will begin to abate? In this article, I will examine the 2004 election results in light of the arguments that have been advanced in favour of electoral reform, applying some of the tests that have been used on previous election results in Canada and in other countries to measure the degree of representative distortion in the new Parliament in comparison with those of the recent past.6
A common method for measuring the representativeness of an electoral system in terms of the political parties is to compare the proportion of seats won by each party with the proportion of the votes that it received. A party that received, for example, 20% of the votes but only 10% of the seats would be said to be under-represented by 10% according to this measure, while a party that obtained 25% of the seats with the same proportion of votes would be overrepresented by 5%. A summary measure created by totalling these discrepancies in the proportion of seats and votes is called the Index of Disproportionality.7 A value of this Index close to zero indicates a perfect fit between seats and votes. Higher values suggest greater distortion of a party's representation in comparison with the intentions of voters.
Table 1 makes this calculation for five political parties that fielded candidates in the 2004 election, comparing these results with similar calculations for federal elections back to 1980. Overall, the electoral system did perform slightly better in 2004 than in the three previous elections, but many of the distortions that have been evident since 1993 continued to exist. Some have even worsened. On the positive side, Liberal overrepresentation was substantially less in 2004 than previously – the difference in the Liberal share of seats over votes dropping to 7% from 16%. The new Conservative Party performed more or less in line with its share of the vote, obtaining 2% more seats than it deserved, compared with a modest degree of under-representation for one of its predecessor parties (Canadian Alliance) and a more serious problem of underrepresentation for the other (Progressive Conservative) in 2000. The negative aspects of the electoral system come through more clearly in the showing of the other parties. The New Democratic Party (N.D.P.) continues to be severely disadvantaged by the FPTP system: it won only 6% of the seats in this Parliament, although it obtained 16% of the vote. The Bloc Québécois, on the other hand, continues to be overrepresented, simply due to the regional concentration of its vote. The Green Party, in spite of fielding candidates in all 308 constituencies and obtaining 4% of the national vote, failed to win a seat. Notwithstanding a slightly better overall performance in 2004, there is little in these results to suggest that the problems associated with the FPTP electoral system in Canada have receded in any significant way.
The failure of the electoral system to accurately reflect the votes of Canadians becomes more evident when the 2004 results are examined by region (Table 2). Here, I report only the summary Index of Disproportionality, which is easily compared across regions, with a value calculated for previous elections. The national improvement in the performance of the electoral system in terms of seats and votes is entirely attributable to Ontario, where the new Conservatives succeeded in winning 23% of the province's seats with 32% of the vote, still a net under-representation of 9%. The N.D.P., likewise, continues to be seriously
In all other parts of the country, the performance of the electoral system was actually worse in 2004 than in 2000, in large part because of the dominance of single parties in a particular region. In the West, the Conservatives are wildly overrepresented, as was the Canadian Alliance in the previous election and before that, the Reform Party. In 2004, the Conservatives won 74% of western seats with only 45% of the vote. In Quebec, the electoral system favours the Bloc Québécois, which won 72% of Quebec's seats in 2004 with 49% of the vote. In the Atlantic provinces, it was the Liberals that gained the advantage, obtaining 69% of the seats in that region with 44% of the vote in 2004 – a net overrepresentation in Parliament of 25%. Nearly all of these patterns are continuations of the types of distortions found in the previous three elections, the effect being a Parliament that is much more regionalized than it should be, or than is healthy in a country in which representation of diverse interests is so important.
The consequences of electoral distortion
The consequences of these distortions caused by the FPTP electoral system in Canada are important ones. Minority voices are muted or, in some cases, shut out entirely. Parties that concentrate their votes in a single province or geographic area are rewarded, while those that appeal to voters nationally are systematically disadvantaged. Were the allocation of seats truly proportional to votes cast on a regional basis, the new Conservatives would have obtained 7 seats in Quebec and the N.D.P. 4, and both parties would be better able to portray themselves as truly national entities, which in the minds of voters they clearly are. On the same basis, the Liberals would have an additional
How does the Canadian electoral system fare by these measures in comparison with other countries with which we might draw comparisons? In Table 3, I compute indices of disproportionality for the most recent election in four other parliamentary democracies. This comparison suggests that Canada shares some of the characteristics of other FPTP electoral systems, with Britain on balance performing worse than Canada in terms of party representation and Australia only slightly better.9 Countries such as Germany or Sweden that employ proportional representation for all or part of their parliamentary seats do much better, because the system itself guarantees a better fit between seats and votes in those two countries. Voters in such systems are far less likely to feel that their votes are "wasted", as tends to be the case in many constituencies in Canada and in Britain. Proportional systems also tend, in general, to have higher voter turnout, although this varies considerably from one case to another, since there are other factors that can affect voter turnout above and beyond the system of representation.10
An idea whose time has come
What might we conclude from this preliminary examination of the 2004 election results in the context of the ongoing electoral reform debate? It is clear that the issue of electoral reform will continue to be widely discussed in Canada in any event, since there is already considerable momentum behind the reform movement. Although the 2004 election was a closer contest, the outcome more uncertain, and the result a minority government, there is little in the outcome that might slow the movement towards reform of an electoral system that remains desperately in need of change. All of the problems of representation that have been evident in the last four elections continue to plague our political system, and to undermine the quality of our democracy. Electoral reform is an idea whose time has clearly come in Canada, as it did in New Zealand in the early 1990s. In the end, the outcome of the most recent election is more likely to advance the cause of reform than to hinder it.

- Although Australia also has single-member districts, it permits voters to order the candidates on the ballot according to preference and then counts these "second choice" votes to determine a winner in constituencies where no candidate has obtained a majority of the votes cast. Thus, although minorities are not necessarily any better represented in Australia than in Canada, the two systems are not really comparable in terms of the effectiveness of individual votes.
- Australia has compulsory voting, accounting for the higher turnout in that case. On the issue of turnout and electoral systems more generally, see Mark N.
