Working to Protect Ontario’s Headwaters, Natural Heritage, and Watersheds


An important part of our mission is sharing our perspective and learning from others on the roles that healthy headwaters, natural heritage, and watersheds play in regional ecological integrity, biodiversity, and economic & social vitality.

See the five watersheds where we colour-coded watercourses by stream order and mapped the catchments of combined first and second-order streams. We call this our superficially meaningful program – allowing people to see the conditions in their local watersheds. .
