Ottawa’s Greenbelt is a unique expanse of land rich in diverse flora and fauna. Spanning 203.5 square kilometres, it encompasses vast forests, rivers, wetlands, farms, and more. But why was such a large green area created in the first place? Let’s dive into its purpose, history, and highlights.
Why Was the Greenbelt Created?

The concept of a Greenbelt emerged in the mid-20th century as part of Jacques Gréber’s Plan for Ottawa. This plan aimed to modernize the city’s infrastructure and manage its rapid growth. By the 1950s, Ottawa was expanding quickly, with new buildings, roads, and annexed territories. The Greenbelt was envisioned to curb urban sprawl, protect rural life in the suburbs, and preserve natural areas.
The idea was brought to life in 1956, intending to support farms, conserve natural spaces, and encircle the city entirely. While the Greenbelt successfully surrounded Ottawa by the end of the 20th century, municipal mergers in the 2000s changed this dynamic. Today, the Greenbelt cuts through the city, forming an arc rather than a complete ring.
What’s Included in the Greenbelt?

The Greenbelt encompasses:
- Forests
- Wetlands
- Fields
- Rivers
- Government facilities
- Ottawa’s international airport
For over half a century, this area has been used for agriculture, environmental conservation, scientific research, forestry, and recreation. The Greenbelt also features numerous attractions, making it a popular destination for tourists and locals alike.
In the 21st century, Ottawa’s Greenbelt is recognized as the largest urban park in the world.

Did the Greenbelt Stop Urban Expansion?
Opinions differ on whether the Greenbelt effectively curbed Ottawa’s growth.
Critics argue that urban development still impacted the Greenbelt, citing the example of Kanata, which expanded alongside the Greenbelt but remains distinct from Ottawa. Other areas like Stittsville and Orleans also developed outside the Greenbelt and grew as independent communities.
While the Greenbelt slowed expansion in certain areas, new suburban developments outside its boundaries continue to emerge rapidly. Thus, the debate over its effectiveness remains ongoing.
