 note = {Canada has been classified as a counter-example to the political theory "Duverger's law," which posits that a single-member plurality electoral system (SMP) tends to produce a two-party system. In fact, a multi-party system appeared after the federal election of 1921. A regional protest party challenged the existing Liberal Party and Conservative Party, resulting in winning the second largest seats in the House of Commons. Particularly, the 1993 federal election marked a turning point in the history of Canadian politics. Canada saw an emergence of two regionally based parties, and the status of the largest opposition was consecutively occupied by third parties.
Since that election, scholars of Canadian party politics have focused on and explained the aspect of change in the party system, party organization, party representation, and electoral campaign strategies. Interestingly, however, if we look at the traditional Liberal Party and Progressive Conservative Party (today's Conservative Party, we can acknowledge that they have continuously emphasized on being "nationa" in their representation; that is, the party should secure support from every region of the country, even after the politicization of a regional cleavage in the 1993 federal election. Being "national" has been their political tenet since the Canadian Confederation of 1867, for it is believed as a means of "national unity" in the country with highly distinctive regions.
With a focus on the aspect of continuity in the traditional two parties, the sole governing parties so far, this article aims to delineate the nature of Canadian party politics, which is unfolded under the undeniable multi-party system. As mentioned above, Canada is a deviation from Duverger's law; paradoxically however, we can empirically observe that the traditional two parties have pursued a return to a two party system regardless of its feasibility. That is demonstrated by the fact that there is an absence of coalition government, but there are many minority governments in Canada as the traditional two parties have persisted in being "national" on their own and not accepted third parties as a coalition partner after the election. In sum, Canadian party politics can be regarded as a pursuit of one that Duverger's law generally assumes., 論説, Articles},
