This chapter talks about Canada's built environment and population growth that predominantly occurs on the urban fringe. It describes Canada as a suburban nation and its largest metropolitan areas, which include Vancouver, Montréal, and Toronto with the suburban residents that exceed 80 percent. It also distinguishes traditional forms of suburban locations that can be characterized by a variety of factors, such as the proportion of single-family housing, car-commuting patterns, population density, and home-ownership rates. The chapter recognizes that the modern suburban landscape is complex and diverse and that there is no single perfect operational definition of suburban. It examines suburban Canada's population that is relatively heterogeneous, compared to rural locations, but is still significantly less diverse than urban Canada.
