About the GTB
The Greater Tkaronto Bioregion (GTB) is 3 million hectares with 10 million people on the north shore of Lake Ontario, also touching Lake Erie and Lake Huron. Defining features include the Niagara Escarpment, Oak Ridges Moraine, the world's largest Greenbelt, and some of the best agricultural land in the province of Ontario. It was originally defined by The Honourable David Crombie, former Mayor of Toronto and federal cabinet minister, with the current GTB Core Team of the Legacy Project following in his legacy.
This region is rich in agricultural potential, home to a wealth of food growers and producers whose work can support a thriving local food economy. The Regenerator is dedicated to strengthening these communities and celebrating the seasons, local foods, and growing methods that nurture soil, biodiversity, and the land.
