"The geography of Toronto's housing market was relatively simple, at least on a generalized scale. Within the city boundaries, the rate of home ownership, and the size and quality of housing...all tended to increase with distance from the city centre. Three inner-city areas were most noted for poor housing conditions: The Ward (Ward 3, Division 6); Cabbagetown (primarily in Ward 2, Division 2); and the large area south of Queen Street between Dovercourt Road and the Don River. In contrast, the best housing conditions were found in neighbourhoods on the western and northern fringes of the city, especially in the area north of "Casa Loma" (an ostentatious mansion in the northern part of Ward 4) and Rosedale (Ward 2, Division 4). However, the degree of conformity to these patterns should not be overstated: there were a few substandard houses in even the most well-appointed areas just as 'slums' typically contained a small number of relatively expensive houses."
