At Tridel, we know that every decision we make today will have a great impact for generations to come. As Canada’s leading condominium developer, we are committed to being an environmental leader in our industry. Years ago, we began the journey of building homes that meet the needs of today’s homeowners while supporting a sustainable future. We believe that understanding the impact we have on the environment is a priority and we build communities that are environmentally responsible, safe and healthy places to live.

At Tridel, we are dedicated to being an environmental leader in our industry, not just because it's a smart thing to do (for our homeowners and ourselves), but because it's the right thing to do.

- Graeme Armster, Director, Innovation & Sustainability


Back in 2000, our President & CEO, Leo DelZotto, and Greg Nevison (Executive Vice President of Construction) in partnership with Jamie James (Sustainability Advisor) pioneered Tridel’s path to sustainability. Together, they recognized the potential to align our development interests and environmental concerns while noting that better-run buildings are more efficient, have positive environmental impact, and produce savings for our homeowners. Three years later, they launched our first green community (Element, 2003) as well as Tridel’s Built Green Built for Life® Program. The first step was taken towards a more sustainable condominium-living future.

To everyone at Tridel, being green is about more than just the environment; it is about doing our part to positively impact all those around us in the unique ways that we can. We see it going beyond our homeowners and the land that we develop, extending to the city and neighbouring communities where we can build capacity for education, employment and community.



As the largest builder of sustainable condominiums, Tridel is committed to building communities that are environmentally responsible, energy efficient, and healthy places to live. Tridel Built Green Built for Life® communities are high performing, meaning they use less energy to run while providing superior comfort to the homeowner. In turn, homeowners pay less money to operate the building and their own condominium suites. We strive to pursue LEED®* (Leadership in Energy and Environmental Design) Gold or Silver certification for our communities.

Built Green Built for Life®

communities feature:

  • Low-flow plumbing fixtures that reduce potable water consumption up to 50%
  • Energy Star appliances and ERVs (energy recovery ventilators) to help you save up to 60% on energy, while improving indoor air quality
  • A portion of our construction materials contains recycled content or have been locally sourced, and all of our paints and adhesives are low VOC
  • Electric vehicle charging stations



Waste Diversion

Doing our part to divert waste from landfill is standard business practice at Tridel. Be it on our construction sites or our Head Office, we do our best to ensure what can be diverted and donated, is.

At Tridel’s Head Office, we actively recycle our electronic waste throughout the year with the help of the Electronic Recycling Agency. Partnering with the Textile Waste Diversion Bin program helps ensure clothing is not unnecessarily thrown in the trash and can repurposed, donated, or recycled responsibly. Thousands of pounds of electronic waste and textiles are successfully diverted from landfill on a yearly basis at our head office alone.

On our construction sites, waste diversion programs are implemented during the construction phase of every project’s lifecycle. Materials such as wood, scrap metal, drywall, concrete, cardboard are diverted from landfills (with a target of zero disposal) and brought to the appropriate recycling facilities. In fact, our practice and preference is to work with suppliers who purchase construction materials and products with recycled content. As a sustainable developer, our commitment for on-site best practices involve the conservation and protection of the natural environment by reducing waste, emissions, and other pollutants, while minimizing the impact of construction. At the same time, we go above and beyond Ontario’s regulations to reduce, reuse and recycle.


Greening Our Corporate Office

Our head office was built in 1969 and has grown with our Company. In 2016 began renovation that were completed in 2018 Before beginning office renovations, we took many key insights and lessons from our energy audit conducted by Provident Energy Management in 2015. As a result, during demolition, we repurposed, donated or recycled our office furniture, carpets and supplies, wherever possible. The Design and Construction Teams worked to improve accessibility and requested the use of sustainable materials. As the health and wellness of those around us is very important, we ensured the use of environmentally friendly products like low VOC paints and committed to improved ergonomic office practices for our employees and guests. In 2018, we audited the as-built construction and increased our focus on reducing our office consumption and waste.

Office Retrofits

In an effort to raise the bar higher for ourselves, we retrofitted our head office with several green features, including:

  • LED bulbs with projected savings of about $8,000 per year, eliminating more than 5,300 KG of carbon dioxide from the atmosphere.
  • Installation of parking on site with electric vehicle / charging stations.
  • Incorporating water filters in our kitchenettes and providing employees new reusable water bottles to discourage the use of one-time use plastic.

Solar Panels

In our continued effort to be an environmentally responsible company, we installed rooftop solar panels at our 4800 Dufferin Street Head Office in 2011.

Tridel Take Action Enhances the Local Forest through Tree Planting

Under the guidance of volunteers from LEAF (Local Enhancement and Appreciation of Forests), members of our Tridel Take Action Team and several volunteers planted over 40 trees in Richmond Hill’s Meander Park.

Over time, our urban forests can be adversely affected by a variety of factors, including development. Forests can become older, lacking in younger trees or face a lack of variety in tree species, among other concerns. The goal of this evening’s event was to help combat those concerns and enrich the neighbourhood’s urban forest.

LEAF (Local Enhancement and Appreciation
of Forests) is a non-profit organization dedicated to the protection and enhancement of our urban forests.

Tree Planting

Delmanor Goes Green

Delmanor incorporated multiple initiatives across their communities, making their practices greener:

  • Proper diversion of all organic waste to be used as compost and avoid landfills
  • Rain water is collected by barrels and then used to irrigate small garden beds within the communities
  • A system that monitors the upcoming weather and automatically calibrates lawn irrigation, depending on the forecast
  • Substitution of harsh chemicals with oxygenated cleaning products


Innovation is a Tridel Core Value and we are dedicated to being a leader in the industry by building environmentally responsible communities, for now and for our future. We are relentlessly committed to quality and sustainable building and we know we can shape condo living in the GTA, while doing our part to save our planet.



The NetZEDTM (Net Zero Energy Dwelling) project, completed in 2018, is a self-contained suite and features an array of sustainable innovations as well as sophisticated monitoring tools to assess the environmental footprint of the unit.

Solar thermal panels intended to heat domestic water and solar photovoltaic (PV) panels producing electricity, enable the NetZEDTM suite to generate as much electricity as it produces. Also contributing to the reduction of overall consumption of energy – improvements to envelope insulation, triple-pane windows, thermal transitions, and the integration of high-efficiency appliances, lighting and HVAC systems work jointly together to create a truly optimal eco-friendly unit.

The results that have been observed through the energy analysis of the NetZEDTM suite at Aqualina over the past two months report several promising figures including a projected 42%* reduction in electricity when compared to a control case (i.e. suite with identical layout and orientation). The suite also produced 304 kwH back to the electrical grid, generating almost $45 worth of electricity in September alone!

A Well Beneath The Well

The Well it is the most ambitious mixed-use community currently under construction in the City of Toronto. It will feature three million sq. ft. of residential, entertainment, retail and workspace, serving over 11,000 people all within one spectacular new community in the heart of downtown Toronto.

Tridel has partnered with district energy provider Enwave to deliver a Deep Lake Water Cooling (DLWC) system at The Well, which is a cooling solution that harnesses the renewable cold temperatures of Lake Ontario. Pipes pull water from deep within Lake Ontario then filter and treat it, before then going through a heat exchange process at a pumping station. The process feeds into the Enwave system before returning the filtered drinking water to the distribution system and delivering it to Toronto residents. The chilled water goes into a cooling loop under the downtown core to be used for air conditioning. The heating loop uses waste heat from an existing heating plant to deliver more efficient and lower carbon heating to The Well and its residents. The cistern will act as a thermal storage facility for both the chilled water in the summer and the hot water in the winter.

Compared to an in-house chiller, Deep Lake Water Cooling uses up to 90% less electricity, eliminates ozonedepleting emissions, and primarily uses renewable lake water, resulting in lower building maintenance costs and an improved environmental footprint.

Carbon Cure

Paving the road for the real estate industry to be a key player in the carbon cap-and-trade economy in North America, Tridel is working with Carbon Cure Technology (CCT) to develop a technology that injects postindustrial carbon back into concrete, making each newly constructed building a permanent depository for carbon that otherwise would have been released to the atmosphere. We have utilized cast-in-place Carbon Cure concrete in our FORM community.
