One MAJOR problems with suburban roads in general are the cul-de-sac setup of the residential streets outside of the downtown or old city of Toronto, York, and East York streets.
While the "cul-de-sac" was supposed to make things safer for pedestrians, it actually made things worse. Walking distances to schools, shopping, or bus (transit) stops became longer. You may think the stops are fine being 500m apart or even 1 km apart, but we tend to forget we still have the side streets to traverse along to get to and from. (Must not forget about the sidewalks.)
