Regional disparities in income have been an important part of the growth of experience of most nation states. Canada is no exception. In a large country, thinly populated and having a wide diversity of resources, cultures, and locational advantages, it is only natural to expect the existence of dissimilar levels of economic performance. In fact, just this diversity of physical and human backgrounds has often provided the primary thrust for variations in natural economic growth. If, therefore, a better understanding of national development is to be obtained, some attention to the growth experience of the subnational units is imperative. This study aims at widening our understanding of the Canadian growth process by focusing on the relationship between regional and national changes since the last decade of the nineteenth century.
