This building demonstrates the highest standards of sustainable design and will play a pivotal role in achieving TRCA’s vision for a sustainable, resilient, and thriving Greater Toronto Region.

Designed to showcase environmental leadership, this award-winning four-story, 86,000-square-foot facility houses an emergency operations center, meeting spaces for the TRCA Board of Directors and staff and accommodates more than 350 employees. It has already been recognized as one of the most sustainable and innovative structures in North America. The building is crafted from mass-timber, a low-carbon construction method that meets the latest Ontario Building Code standards. Its design emphasizes energy efficiency, cost-effective operations, and a minimal environmental footprint, all while fostering a modern, collaborative workspace.

The facility incorporates geothermal and radiant heating systems alongside energy-efficient systems to reduce operational costs and maximize environmental benefits. The building also highlights green infrastructure systems, managing stormwater runoff via rainwater harvesting gardens, bioswales, and permeable pavement.

Nestled next to the Black Creek ravine on TRCA lands, and adjacent to walking trails and transit options, TRCA’s new administrative office building encourages active transportation, health, and wellness for its employees. Its integration into natural surroundings and re-use of materials from TRCA’s previous head office on the same site for walkways and landscaping exemplifies TRCA’s commitment to ecological harmony and environmental conservation.
