In 1968 NCC conserved the first project in Ontario — Cavan Swamp and Bog. This exceptional complex of bogs and other wetlands covers 3,400 acres (1,340 hectares). The site is now the Cavan Swamp Wildlife Area and shelters an abundance of wildlife, including 22 species of orchids.
Today, NCC has helped to protect more than 200,000 acres (82,000 hectares) in Ontario. From the north shore of Lake Superior to Pelee Island in Lake Erie, NCC works to protect the province’s most significant natural landscapes.
We focus our conservation work in priority areas, identified through science-based planning initiatives. These are areas where species and ecosystems face the greatest threats.
In Ontario, we work in 17 priority natural areas. Together, these landscapes span the wide range of habitats and ecosystems that make Ontario unique.
