The following publication prepared by Environmental Defence is a good source of information for groups wishing to fight sprawl.
The Greater Golden Horseshoe (GGH), Canada’s largest urban region, will undergo a profound change as it grows to accommodate an anticipated 4.4 million new residents by 2041, making it home to nearly 13.5 million people.
The decisions we make about how to accommodate this growth will determine what types of communities we live in, how much time we spend stuck in traffic, the quality of the air we breathe and whether our farmland and forests continue to provide us with food and habitat for our unique wildlife. There’s no question that new housing will be needed. The question is what form it will take.
