A major objective of this article is the reexamination of canvassing-voting relationships analyzed by Clarke, Jenson, LeDuc and Pammett in Political Choice in Canada. However, this study distinguishes itself in two major ways. First, usage is made of multivariate techniques, a necessity in view of the number of variables that ought to be taken into consideration. Secondly, two conceptually important types of variables are incorporated; namely, the number of parties canvassing potential voters (“competitive contacting”) and the degree of party competition in the constituency (“competitive context”). The results indicate the relevance of these two types of variables, although varyingly so. Thus, “reinforcement,” the principal canvassing effect uncovered, is related to competitive contacting, independently of the competitive context. On the other hand, possible “recruitment” and “conversion” effects are associated with particular attributes of both factors. These results, along with some unexpected ones, underscore a suggestion advanced in the article for renewed research into the subject of canvassing.
