Toronto sits within the Greater Golden Horseshoe, a densely populated, horseshoe-shaped region wrapping around the western end of Lake Ontario in southern Ontario, Canada.
This geologically diverse area includes the Niagara Escarpment, Oak Ridges Moraine, and fertile plains. It encompasses Toronto and surrounding regions: Hamilton, Niagara, Waterloo, York, Durham, Peel, Halton, Simcoe, and Wellington.
The Horseshoe is Canada's economic heartland, hosting over 9 million people.
