Evergreen Brick Works has long been one of Toronto’s most beguiling attractions, a former brick factory transformed into a one-of-a-kind ecological playground, complete with farmer’s market, public art, demonstration gardens, hiking trails and educational programming. Last year, it also became a much-needed testing site for dozens of ventures developing new cleantech solutions. Below, Dominique Ritter takes a look at this living laboratory.

If you build it, they will come … and test their tech.
Toronto’s Don Valley Brick Works, an historic industrial site that includes a former quarry and brick factory, has long been a place where things get built. Over the past 16 years, its role as a large-scale environment community centre with a mandate to support sustainability, biodiversity and innovation has been slowly evolving under the auspices of the national non-profit Evergreen. With $150 million in investment to date, factory buildings have been restored, the watershed rehabilitated and new projects to strengthen climate resilience have launched.
The latest phase of its metamorphosis is now underway: in partnership with the Ontario Centre of Innovation (OCI), the Brick Works is now a Technology Development Site. In short: it’s where small and medium-sized businesses (SMEs) in climate tech, construction and urban innovation can put their concepts into action. As the Brick Works continues to build, innovators have the opportunity to test and validate in a real-world setting.
“Evergreen’s mission has long been focused on public infrastructure and building better public spaces in Canada for people and the planet,” says Martin Canning, executive director of community innovation at Evergreen. “[We wanted] to construct a campus and show Toronto, Ontario, Canada and the world what’s possible when we’re thinking of the future of cities.”
As one of 10 of the OCI’s Technology Development Sites, the Brick Works serves as a testbed that provides startups with commercial opportunities, investment bridges and operational validation. It also has some unique attributes that make it a particularly effective experimental space for startups: a 16.5-hectare site, a wide range of projects SMEs can participate in (from nature trails to new construction) and a willingness to make things happen quickly.
So far, the Brick Works has collaborated with about 35 startups on projects that range from drone technology to next-generation energy transition. Toronto-based startup Trax recently concluded a trial of its AI-powered platform that assesses regulatory compliance. TerreSky, a drone consulting firm, is currently training its AI model to track plant growth and the spread of invasive species in the Don Valley. Another venture exploring the opportunities at the Brick Works is Enersion, a Toronto cleantech startup developing heating and cooling systems that operate on a fraction of the energy required to power a traditional heat pump.
“There’s hardship that goes along with being the first-of-a-kind,” says Hanif Montazeri, the CEO of Enersion. “The Evergreen team loves innovation and they want to be the first-mover. They want to be a participant rather than an observer of innovation.”
Novel tech needs a place to develop and that’s what the Brick Works and its “perennial construction” can provide. For the team at Toronto startup Lowfoot, that opportunity allowed them to deploy their energy-analytics platform for the first time, work out some kinks and provide validation of their solution. The multi-purpose nature of the site means that the company now has case studies for a variety of commercial applications.
“That testing context isn’t just an accelerator. It’s a bridge to investment, and it’s a bridge to immediate commercial transactions,” says Canning.
If you build it, they will test. And then, the hope is, they’ll build a lot more. — Dominique Ritter

This week, Sofia Dawson, an intern in the Marketing and Communications department at MaRS and a fourth-year student at Concordia, shares what she’s consuming.
A thoughtful conversation to tap into: “I’ve spent many an hour listening to Dax Shepard’s Armchair Expert, most recently an episode with technologist, neuroscientist and Stanford professor, David Sussilo. Armchair Expert regularly gets into the nitty-gritty details that shape a person’s life and career and the Sussilo ep is no exception. It dives deep into the professor’s tumultuous childhood and how those early years drove his desire to better the world.”For more, visit our jobs page
