The Greater Toronto and Hamilton Area (GTHA) in Canada includes the city of Toronto, the city of Hamilton, and the regional municipalities of Halton, Peel, York, and Durham.

This 8,244 square kilometre urban region, home to 7.3 million people, is Canada's commercial, distribution, and financial core. Almost half of Ontario's emissions come from this region. TAF acknowledges these boundaries were created by settlers and do not reflect the Indigenous people who have occupied these lands for thousands of years or their respective traditional territories or treaties.
