In the 1962 federal election in Canada, to the great surprise of almost all political observers, the Social Credit party obtained 26 per cent of the votes in Quebec—as against 39 and 30 per cent for the Liberals and the Progressive Conservatives respectively—and gained 26 of the 75 seats of the province. If one considers that in the preceding election the Social Credit Party had obtained no seats and less than one per cent of the vote, there were good reasons to be astonished.
The purpose of this paper is, first, to show in what ways the political situation at the federal level in Quebec was particularly conducive to the rise of the Social Credit party and, second, to present a general hypothesis concerning the political factors which account for the rise of third parties during other periods, and elsewhere in Canada.
To be sure, the rise of Social Credit, as well as of other third parties in Canada, was not the result of a single overriding factor. Many facets of reality—social, economic and political—were involved. In the case of Social Credit, in particular, economic “strains” were as important an independent factor as the political conditions to be discussed below. As can be seen from Table I, our survey data clearly show the strong effect of unemployment in the respondents' family, which accounts for some 30 per cent of the variation in the support of Social Credit.
