Project: Toronto Island Flood Mitigation
Description: The Toronto Island Flood Mitigation Project aims to protect the islands from future high-water events through long-term flood and erosion control measures. Key engineering components include shoreline stabilization, installation of naturalized berms, and enhanced drainage systems. The project also involves constructing flood barriers and upgrading existing infrastructure to withstand extreme weather conditions. These efforts will safeguard residents, businesses, and public spaces, ensuring the islands remain a safe and enjoyable destination.
Role: 4Sight’s role is to provide Subsurface Utility Engineering services to manage identify the presence of existing utility infrastructure that could be impacted by the proposed flood mitigation measures being designed for the island.

Some of the 4Sight team attended the Connect: Women Building Tomorrow event last week. Being surrounded by so many women sharing their stories, challenges, and passions was incredibly inspiring.

Next week we will be at the AOLS 2026 conference at the Hilton, Markham from 3rd-5th March. If you’re attending then please stop by at Table 6 and say hello, we would love to see you there.
