Scaling Sustainable Housing: A Tour of Westbend by Mattamy Homes
Tour Westbend: One of Toronto’s First Geothermal Condo Buildings
Discover how Westbend by Mattamy Homes is setting a new standard for sustainable development. As one of the first condominium projects in Toronto to integrate a geothermal system, Westbend is designed to reduce operational carbon emissions by 55% compared to a traditional building—all while maintaining constructability and product quality.
As one of North America’s largest homebuilders, Mattamy Homes is committed to industry-leading carbon reduction by embedding sustainability into every stage of development—from land acquisition to construction completion. Since 2021, Mattamy has integrated geothermal across its mid-rise portfolio, delivering efficient, low-carbon heating and cooling to over 1,000 homes.
