About Us

The Ontario Greenbelt Alliance is a watchdog and defender of Ontario’s innovative Greenbelt. Our vision is to make the Greenbelt a valuable and permanent part of Ontario’s landscape. The Alliance is coordinated by Environmental Defence.

Our story

The Greenbelt Alliance was instrumental in establishing the Greenbelt in the lead up to 2005, growing it in the intervening years and making it the largest permanently protected Greenbelt in the world. Its members draw attention to the issues that are affecting the Greenbelt, organize opposition to developments that threaten the Greenbelt, work together and share information on key regional issues, and support each others’ efforts in their local communities.

We work to ensure that the integrity of Ontario's Greenbelt is not undermined by inappropriate development, poorly planned infrastructure, quarries, or other uses, while also advocating for increased protection of natural areas within the Greenbelt.

We are also working to build on growing support for expanding the Greenbelt so that the benefits of its smart planning framework can be extended to adjacent areas that are under serious and unsustainable development pressure.

The Greenbelt is a living, growing system for sustaining a healthy environment and vibrant communities.
