St. Clair staircase

A project to restore the long-closed access to the ravine at St. Clair and Avoca is being initiated! A big hooray to that. Phase 1 will be a geotechnical investigation informing the feasibility and positioning of the staircase and Phase 2 will be a design-build contract to expedite implementation.

Tracking the Health of Yellow Creek

Digital Waters is a Toronto-based non-profit developing affordable, made-in-Canada water monitoring technology to better understand and protect our local waterways. We were inspired by Toronto’s ravines. They are amazing veins of nature that stretch across town, always lush and green in the summers and the perfect way to take a break from life. But nothing lives in the waters that carve out Toronto’s ravines.

Spring brings hope: the Rosehill Garden – building community

The Rosehill Garden is part of the David Balfour Park. The park traces its history to 1873 when the area became Toronto’s first reservoir, part of the City’s public water distribution system. The gardens were rebuilt in 2022, after a massive 4-year rehabilitation of the reservoir.
