Canada-US metropolitan density patterns: Zonal convergence and divergence

The paper compares density patterns of the three largest Canadian metropolitan regions with those of a sample of 12 U.S. urban areas with comparable populations. It verifies if such patterns support claims of Canadian urban distinctiveness prevalent within this country's research literature. Findings indicate that regional differences among U.S. cities are as important as cross-national distinctions. Measures of centrality and overall density place observed Canadian metropolitan areas within the same category as older U.S. East Coast metropolitan areas. Inter-city comparisons of historically and geographically defined zones suggest a period of cross-national convergence before World War II, when the inner city was developed, followed by a period of divergence from the 1940s to the 1970s, when the inner suburb was built. The development of the outer suburb, which began in the early 1970s, marks a return to cross-national convergence. These results question the continued relevance of the literature on the distinctiveness of Canadian urbanization.
