CAGBC Award winners honoured for achievements in green building 

June 18, 2026 – Montréal – The Canada Green Building Council (CAGBC) unveiled the winners of the CAGBC Awards at the Building Lasting Change™ (BLC) conference in Montreal. The CAGBC Awards recognize Canada’s most efficient, effective, and impactful buildings as well as the individuals or teams contributing to the success of Canada’s green building sector.

From deep carbon retrofits to leadership in market transformation, this year’s winners highlight how resilient, energy-efficient and low-carbon strategies are being implemented across Canada today.  

“The projects and leaders receiving CAGBC Awards demonstrate how their commitment to sustainability drives innovation in the industry and strong performance outcomes which translate into clear business benefits,” said CAGBC President and CEO Thomas Mueller. “What stands out is the level of practical implementation and how these approaches are replicated and adapted across markets, asset classes and climates.”

Winner: Rayside Labossière offices expansion
Location: Montreal, Quebec 

By eliminating fossil fuels and utilizing a carbon-sequestering mass timber structure, the Rayside Labossière expansion achieved Zero Carbon Building and LEED Platinum certifications. Passive design strategies including triple-glazed windows, green roofing, and shading vines reduced thermal loads, allowing the building to rely on a compact closed-loop geothermal system for heating and cooling. In addition, aa 14.6 kW rooftop solar array supplies 17 percent of the building’s power, alongside heat recovery ventilators and smart thermostats that contributed to a 60 percent reduction in annual energy consumption. 

Winner: Hôtel de ville de Montréal
Location: Montreal, Quebec

Built between 1872 and 1878, the historic Montreal City Hall underwent a major architectural restoration that demonstrates how heritage preservation can result in significant carbon reductions. Key interventions included tightening the building envelope, restoring 169 historical windows to achieve a 75 percent increase in airtightness, and replacing the legacy fossil-fuel steam heating with high-efficiency air-to-water and water-to-water electric heat pumps. By tying these upgrades directly into Quebec’s clean hydroelectric grid, the project ultimately achieved a 99.6 percent reduction in greenhouse gas emissions.

Winner: təməsew̓txʷ Aquatic and Community Centre
Location:  New Westminster, British Columbia

Represented by: Jenaya Schroh, Marketing Specialist, HCMA 

The t’m’sew’txw Aquatic and Community Centre is designed to enhance community wellness while advancing ambitious climate action goals. The building’s design honors Indigenous reconciliation by aligning with the natural topography and utilizing sustainably harvested local mass timber. Achieving Zero Carbon Building – Design Standard and LEED v4 Gold certifications, this all-electric facility aims for a 92 percent reduction in greenhouse gas emissions (GHG) compared to the building it replaced. The new facility utilizes passive design strategies, a rooftop solar array, and an innovative gravity-fed filtration system to improve energy and water efficiency.

Completed in August 2025, GEO Park is a six-story, 176-unit residential building designed to provide sustainable and affordable housing for families and students. Certified under the Zero Carbon Building – Design Standard, this project achieves its net-zero goals through an all-electric geo-exchange heat pump system, optimized ventilation, and high-performance double-glazed windows. Embodied carbon was significantly reduced by utilizing ultra-low-carbon concrete, which saved 40 percent in carbon emissions compared to traditional baselines. Along with a green roof and many amenities, GEO Park proves that eco-friendly, zero-carbon design is achievable within an affordable housing context. 

Green Building Champion

Winner: Ryan Zizzo, Founder & CEO
Organization: Mantle Climate

Ryan Zizzo is a recognized national leader for his trailblazing work on embodied carbon policy. Serving on CAGBC’s Zero Carbon Steering Committee from 2018-2023, Ryan advocated for embodied carbon requirements across the Zero Carbon Building Standards. His research and expertise have guided federal, provincial and municipal approaches to circularity and low-carbon procurement. As a volunteer, Ryan contributes as part of the organizing committee for CAGBC’s Embodied Carbon Summit, the technical committed for embodied carbon for the 2030 National Building Code, CSA Group’s A512 Circular Construction Technical Committee and the Carbon Leadership Forum – Toronto.

Winner: Royal Bank of Canada (Transformative Climate Action in Practice)

The Royal Bank of Canada (RBC) is advancing decarbonization in the commercial real estate sector strategies that focus on fossil fuel reduction, renewable energy expansion, and high-impact carbon investments. RBC has committed to fully electrifying its Canadian retail network’s HVAC systems by 2035, earning a 2025 CREST Award and achieving Zero Carbon Building – Performance certifications for multiple branches. RBC also supports grid decarbonization by sourcing 100 percent of its electricity from regional renewable projects. To address tenant-related emissions, the bank actively collaborates with landlords, securing agreements to transition over 2.5 million square feet of leased office space to net-zero by 2040.
