connecting living and built environments
about GINKGO
We believe that small positive steps can have a big environmental impact.
Ginkgo Sustainability was founded in 2010 with a mission to connect living and built environments. We see an economically viable way to live in urban cities that create meaningful jobs, build mindful communities and advance responsible ESG investments.
In Canada we were one of the first, today we are the largest installer of green roofs with 3.2 million square feet covered and counting. We help clients achieve and maintain their green buildings with hands-on expertise, quality workmanship at a fair price, and a safety-first and last policy.
Over the years we have developed and introduced more products and services. Our living walls and maintenance divisions have grown to new heights. We now offer air purification and monitoring systems, grounds, planters and moss art installations. An organic approach to doing business means you can always count on solutions tailored to your needs.
Today business is augmented by technology and ours is no different. We developed SoiLiNQ™, a SaaS based soil monitoring system designed for green construction, agriculture and landscape professionals. To stay ahead of the curve, we built a Canadian Research and Development Centre bringing high quality, best in class air filtration systems and smart green walls to the market. We are positioned to respond to the needs of our time.
Experience. Each of us brings our own, and our team are masters of their crafts. Their knowledge extends to environmental studies, biophilic design, plant design, landscape architecture, and human behavioural sciences, making us well placed to lead 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.
what we do
Rely on us.
We want you to understand your options pre and post construction. With strategies to take you through every stage of the building process, our insight makes for a smooth on-site.
Our consulting portfolio is turn-key and includes assistance with structural assessments and green infrastructure feasibility studies. We begin with an introduction to the applications and benefits of biophilic design. Creating intentional spaces makes for a better connection between nature and humans and optimizes the health of our cities. We can facilitate your building achieving LEED and WELL certifications, both points-based credit systems that recognize your company’s commitment to advancing better building and better employee well-being.
If you are considering a green roof, a living wall, or other living architecture we’ll help you make an informed decision.
Custom design plans.
Solutions that speak to your vision, created in Computer-Aided Design (CAD). Our collaborative approach starts with listening. It’s followed up with recommendations based on decades of combined experience on hundreds of green projects. Decisions that consider every facet of the project from form to function and built to be environmentally and economically sound.
We support your individuality and work to have it reflected in the finished project.
We know the right stuff.
In 2009 Toronto was the first city in North America to introduce a Green Roof by-law for new development and additions that are greater than 2,000 m² in gross floor area to integrate natural vegetation. We were there.
As installers of green infrastructure in commercial, institutional, industrial, multi-unit and single residential construction we offer experience, and support you can count on. Our certified crews are trained by the manufacturers of the roof and wall systems, making us well equipped to recommend the one that best meets your building and your sustainability goals.
Our roof install service includes assisting you through the permit process and submitting to municipal green roof incentive programmes. Grant funding applies to vegetative metres covered and can include savings on structural assessments.
We take no shortcuts. Our safety standards are exceptionally high which is why our first step is always a site evaluation to determine that access points are secure before crews begin.
Trust us to do it right.
Use a specialist, not a generalist.
Ongoing maintenance is integral to protecting your green roof and living walls. Maintenance is a control measure that can avert potential costly future repairs. Regular scheduled site inspections keep on top of invasive species and weeds so that your roof is debris free, and your system warranties are intact.
Customized living walls require service checks for irrigation and to ensure that drains aren’t blocked so plants get the nutrients they need. We check on the stress levels of plants to keep disease and pests at bay. Fertilization, light optimization and pruning at the right time keeps the living products flourishing.
Your investment deserves attention and protection.
Our approach to innovation is to develop, design and deliver products that influence the ecosystem today and tomorrow.
We are introducing SoiLiNQ™ a dynamic, extensible soil monitoring system designed for sustainable construction, agriculture and landscaping professionals. Our GreenTech solution delivers a new approach to maintenance that connects and protects your green assets. The goal is to provide your business with transparent, scientifically sound, actionable data that lowers your operational costs and increases your profitability. It can be accessed anytime, anywhere on any wireless device.
GINKGO Air offers a product line of air purification systems. Aether, Stomata and Smart Green Walls are all designed and built to absorb harmful VOCs found in products we use daily that can have adverse effects on our health. 90% of our time is spent indoors where we are exposed to toxins. Our suite of systems are low to no maintenance, self-monitoring and fully customized.
We want to create green building literacy.
Our team is eager to share our industry expertise and supporting evidence-based research so more corporations, individuals and institutions respond to the ESG call to action. Building greener is a purposeful investment that impacts the life of constructed spaces and their occupants.
Customized outreach programs geared to your industry are available on multiple platforms. Webinars, speaking engagements and think-tanks designed for your group and your goals.
We advocate for green inclusion.

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.
