The Ontario Greenbelt Alliance (OGA) is a coalition of community groups, farmers, environmental organizations, and concerned citizens working together to protect, strengthen, and expand Ontario’s Greenbelt.



We stand for the Greenbelt — the farmland, forests, and water that sustain Ontario. Our mission is to ensure it is permanently protected, expanded where needed, and defended against threats that put our communities and environment at risk.

"I was in my 20s when the Greenbelt came to be, but in many ways, I feel like I was raised around Greenbelts my entire life. Growing up north, I was surrounded by vast stretches of wetlands, forests, meadows, and fields—places left to be and flourish without human impact.
Ontario’s Greenbelt provides the same balance I grew up with up north. We live in a fast-growing region, and the demands on our natural environment and farmland are ever-increasing. When I think about the future of the Greenbelt, I think about the legacy we are giving to our youth.
I think about how a younger version of me was able to find peace, beauty, and a sense of awe in these landscapes—landscapes that connect all things, including us. That is at the heart of the Ontario Greenbelt Alliance: working closely with member groups, steering committee members, and people across Ontario to protect what connects us all.
The beauty I was raised around—the parts of ourselves we find while gazing across a farmer’s field, or an ever-stretching meadow, or looking down from a rocky cliff onto a vast swath of forest below, or the rivers and lakes that feed us all—brings me hope. And beyond that hope, for everyone who knows the Greenbelt, I hope they also believe in its vision—that it can be a love letter we write to ourselves and to future generations. A promise that the places that inspire us, bring us peace, and provide for us are worth protecting."
