The Greenbelt Plan region is unequivocally a human region—a landscape shaped by policy and planning rather than purely natural forces.
Established by the Government of Ontario in 1959, the Greenbelt Plan was created to protect agricultural land and natural heritage systems surrounding Toronto and the Greater Golden Horseshoe from urban sprawl. It represents a deliberate human decision to designate over 2 million acres of farmland, forests, wetlands, and watersheds as permanently protected.
While the Greenbelt encompasses diverse physical geography (the Niagara Escarpment, Oak Ridges Moraine, fertile farmland), its boundaries were drawn by policymakers, not geological processes. The region's identity stems from its legislative status and planning function.
As one of the world's largest and most successful greenbelts, it demonstrates how human governance can shape regional geography to balance development with environmental protection and food security.
