The Ontario Greenbelt Alliance is a diverse multi-stakeholder coalition of groups who share a common vision for the environment. The Ontario Greenbelt Alliance believes that a strong economy and a beautiful, well-protected Greenbelt go hand in hand. Our businesses cannot prosper if goods and services are stuck in gridlock. Family recreational opportunities are diminished if there is no green space left to enjoy. A future free of polluted air and water depends on improved planning today.
