Seat Imbalance in Provincial Elections Since 1900: A Quantitative Explanation

Alan Siaroff


The focus of this research note is on the causes of imbalanced, if not indeed lopsided, election results that yield dominance within provincial legislatures. Two alternative areas of explanation are assessed here. The first relates to electoral system factors. Certainly, the single member plurality electoral system and its resulting disproportionality is a key part of the argument here. Yet this cannot be the whole story, not least because election results are not so lopsided in every province, nor indeed at the federal level. Thus what also will be assessed in this area are two other, related, aspects of elections: the total size of the assembly and the number of individual constituencies, as well as relevant party system factors.
