Abstract
This article traces the contribution of the Consumers' Association of Canada (CAC) to the advancement of Canadian consumer protection legislation in the decades after World War II. The theory of the consumerism life cycle shows that the CAC as the spearhead of grassroots consumer activism in Canada was able to address effectively consumer concerns at both the administrative and policymaking levels of government. Analysis of the rise and fall of consumerism in post-WWII Canada from the perspective of the consumerism life cycle also might well have implications for the further development of that theory.
