Abstract
This paper demonstrates that over the 25-year period, 1971-96, the majority of Canadian cities have undergone transition towards an increasingly decentralised urban form. The trends, however, are quite diverse, pointing to fundamental differences in the respective importance of growth in central and outer parts of the metropolitan area. On the whole, the relatively high densities observed in Canadian central cities, in comparison with US ones, appear to reflect residual centralisation rather than continued growth in metropolitan regions' innermost parts. Only Vancouver, and to a lesser extent Toronto and Victoria, exhibit indisputable evidence of post-1971 central-area growth. The predominant trend has been towards suburban-style, low-density expansion, albeit with considerable intercity variation regarding changes in central-area and suburban density. Findings presented here point to previously unidentified trends towards recentralisation in a few CMAs and, in about half of the surveyed metropolitan areas, densification of suburban tracts.
