Toronto Courthouse
Phased overhaul of Ontario’s busiest courthouse
Cumulus is leading the revitalization of the iconic Toronto Courthouse on University Avenue for Infrastructure Ontario and the Ministry of the Attorney General. As the busiest courthouse in Ontario and a Provincial Heritage Property a strategic phased implementation plan was required to ensure continued operations. This project draws on Cumulus’ experience, expertise and intimate understanding of existing facilities, courthouse function supporting comprehensive evaluation of design options and impact on building system integration.

Cumulus assessed the feasibility of maintaining courts operation under two scenarios for phased sprinkler and fire alarm upgrades. Our approach involved laser scanning, ventilation mapping, a validated BIM model, and over 140 site investigations.
Cumulus evaluated a 22-phase, 11-year plan preserving administrative unit integrity and an 11-phase, 7.5-year plan aligned with building ventilation zones. The study now informs IO’s long-term capital planning.
Cumulus and the engineering team finalized documents for the first phase of the implementation plan, executing the vertical riser infrastructure throughout the building facilitating future incremental extension of the systems.
