This brief by CVC talks about the benefits of [[Blue roofs]] and how they are emerging as a recognized as an innovative rooftop stormwater management solution that provides flood protection and drought resistance. Instead of quickly conveying stormwater away from a property, blue roof systems temporarily capture rainwater until it either evaporates from the rooftop, is sent to rainwater harvesting storage tanks. The CVC head office Building A is typical of most flat roof buildings across North America. In July 2020, Intact awarded the CVC a Climate Action Grant to pilot a Smart Blue Roof system on-site to evaluate real world performance and scalability in a Canadian context. Piloting and monitoring a smart blue roof system at the CVC office begins the summer of 2022.

This three-year study, initiated in 2003, evaluated the hydrologic, water quality and biodiversity benefits of a green roof located on a multi-story building at York University in Toronto, Ontario. The performance of the green roof was compared to a conventional (control) roof through water quantity and quality analysis and hydrologic modelling. A biodiversity assessment conducted investigated flora, birds and bees on the green roof. Continuous precipitation and runoff data collected over 18 months (excluding winter) indicated that the green roof discharged 63% less runoff than the adjacent control roof. Flora monitoring showed that despite the fact that the original green roof seed mix was primarily non-native, its low-nutrient, low-competition environment would be conducive to the establishment of conservative or rare native plants of concern.
