Nature Inspiration Awards

We’re honoured to announce that we’ve won the Community Action Award at the 2023 Nature Inspiration Awards by the Canadian Museum of Nature.

Stewardship Program

Every Wednesday we meet at our stewardship site in Sun Valley to remove invasives, plant native species, and do everything we can to return this land to a thriving diverse habitat.

We protect and restore Toronto’s beautiful Don Valley.

The Don Valley is a wonderful part of Toronto’s ravine system, providing green space, natural habitat, and outdoor recreation in the core of the city. But the Don is under constant pressure from litter, pollution, invasive species, urban encroachment, and land development.

Our mission is to make sure everyone knows: Don’t Mess with the Don!
