Message from the President


Founded in 2010, Ginkgo Sustainability Inc. was born out of a love for the environment and a passion for sustainable business. We are driven by our mission to connect the living and built environments through the installation of living roofs and the installation and manufacture of living walls.

Since our founding, our GingkoRoofs division has installed living roofs throughout Ontario, from the Waypoint Centre for Mental Health Care in Midland, to Exhibition Place in Toronto and the Perimeter Institute for Theoretical Physics in Waterloo. Our recently launched GingkoWalls division seeks to replicate the success of GingkoRoofs and is looking to establish a strong foothold in the living wall market.

In the coming years we aim to continue being the leading living roof installer in Ontario and to position our living walls division at the forefront of the industry. Through our dedication to high-quality workmanship, our clients, sustainable and ethical business practices, and to product research and innovation, we believe we can achieve these goals.

Our team has the depth of experience in the green building industry to realize our clients’ projects with excellence and efficiency, and to accomplish our business’ long term objectives. We also strive to expand our knowledge through continuous industry learning and study, with the Green Roof Professional accreditation program being one example.

With over 100 green roofing projects completed since 2010 and the development of our GingkoWalls division, we invite you to join Ginkgo Sustainability in connecting the living and built environments.
