A lot of the change in the suburbs is driven by change in the city. Toronto is among the five largest cities in North America and has a tower building boom going on that appears to outdo the others on the list combined. The idea of finding a family home in the central city or the inner, older suburbs of Toronto seems to be rapidly becoming obsolete for all but the wealthiest people. This brings Toronto into line with many other global cities where international financial muscle, physical geography, and high population growth rates shape life. This type of change pushes working people outward. The distance pushed goes up even more for those in social difficulty.
