This paper has two major components, the first of which is an exploration of the dynamics of Canada's shopping centre network during the 1990s. The second is the development of a software application entitled Canadian Shopping Centre Analyzer. In exploring the shopping centres, analyses are undertaken with respect to various categories of shopping centres, recent and historic development, power centres, and retail sales statistics. Comparisons are generally made at the provincial and Census Metropolitan Area (CMA) or Census Agglomeration (CA) levels of geography. The prototype Canadian Shopping Centre Analyzer software is designed to provide users with the freedom and some tools to conduct their own analyses of the national shopping centre network, as well as to demonstrate the capability that current technology has to revolutionize the manner in which organizations such as the Centre for the Study of Commercial Activity (at Ryerson Polytechnic University) disseminate data to their membership and to the public.
