connecting living and built environments
about GINKGO
We believe that small positive steps can have a big environmental impact.
Founded in 2010, Ginkgo Sustainability connects living and built environments through innovative, economically viable green infrastructure solutions. We believe in creating meaningful jobs, fostering mindful communities, and driving responsible ESG investments.
As pioneers in Canada’s green building movement, we’re proud to be the nation’s largest installer of green roofs, with over 3.7 million square feet and counting. We support our clients with hands-on expertise, quality craftsmanship, and a safety-first and last policy.
Our products and services have grown organically over the years. We offer maintenance services, custom living walls, grounds and moss art installations. With GINKGO you can always count on solutions tailored to your needs.
Today business is augmented by technology and embracing the next chapters of sustainability. We developed SoiLiNQ™, a soil monitoring SaaS platform for green construction, agriculture, and landscape professionals. We built a Canadian Research & Development Centre, bringing best-in-class hybrid air filtration systems and Smart Green Walls to the market.
Experience. Each of us brings our own, and our team’s expertise blends environmental science, biophilic design, landscape architecture, and human behavior, making us uniquely equipped to guide you to green.
Connecting living and built environments is our small step to ensure that like the Ginkgo tree we named ourselves after, we prosper for generations to come.

Christian Mahlstedt
Founder & President
B.A. (Hons), M.B.A., LEEDAP
BIO »
Christian is the brick the business was built on.
An early adopter of green infrastructure, the company he started, was and remains inspired by a vision to connect nature to buildings. His thoughtful leadership is rooted in finding ways to work with developers, construction companies and homeowners to make sustainability affordable.
He brings full-circle experience as he previously estimated, installed and managed green roofs. His grassroots beginnings have led to seats on several boards that advocate for the economic, social, and environmental benefits of living architecture.
Prior to his foray into business, for reasons unknown, he completed a degree in philosophy. After hours you may find him running an obstacle course or packing a bag ready to trek around the globe.

As our starting quarterback she carries the team.
Carrie is an ambassador for the environment and a solution driven leader that makes room for everybody and brings a nothing is impossible mentality. She also brings 15 plus years of experience in management and business development in diverse industries. At GINKGO she heads up our day-to-day operations and is fully immersed in all the moving parts.
When she’s not running the office marathon, she’s considering running a city marathon. An adventurer who chases new experiences across the globe, she is drawn to water and all the sea creatures that call it home.

Jenny delivers.
She has spent the last decade with GINKGO in a pivotal operational role. Her extensive construction and project management skills make her a force of nature. A flare for transparent communication that delivers flawless green roof installations because she manages potential problems before we know there is one. The consideration of the smallest of details keeps our teams a step ahead. Responsible, decisive, and budget conscious she steers people and projects in the right direction.
Our rarely idle, natural planner is an adventurer with heart. She enjoys camping, music festivals, travelling, and playing sports in recreational centres across the city.

Lead Estimating Manager

BIO »
Donald has a pulse on environmental solutions from a global perspective.
At GINKGO he mentors and trains the next generation of sustainable leaders. With over 20 years of experience, 300 green roofs installed globally, he brings invaluable knowledge to the team. Though he likes the nicheness of the industry he envisions a time that it is simply, the way it is. His motto is something green is something good.
Originally from Belgium, chocolate cravings are melted into his DNA. So is gathering his family in a mini trailer in search of mountains, water, and space. At home he lives off their land and cheers on his son at multiple sporting competitions.

Joel Ferguson
General Manager
GINKGO Air & Director of Innovation
BIO »
With Joel something exciting is always taking shape.
A veteran of innovation, he has spent years studying air pollution and the harmful effects it has on people. At our Research and Development Centre he designs with purpose and oversees manufacturing for the GINKGO Air line of products. He affectionately refers to the lab as his sandbox and his capacity to work with, and retain data is inspiring. His global vision is green houses on every continent to make the world a better place to breathe, belong and be in.
When he allows himself downtime he likes to cook, listen to jazz, but mostly he contemplates his next revolutionary solution.
