TheGreenbelt is a 203.5-square-kilometre (78.6 sq mi) protectedgreen belt traversingOttawa,Ontario, Canada. It includes green space, forests, farms, and wetlands fromShirleys Bay in the west and toGreen's Creek in the east.[1] It is the largest publicly owned green belt in the world[2] and the most ecologically diverse area inEastern Ontario.[3] TheNational Capital Commission (NCC) owns and manages 149.5 square kilometres (57.7 sq mi), and the rest is held by otherfederal government departments and private interests.[1] Real estate development within the Greenbelt is strictly controlled.[citation needed]
The Greenbelt lies within eight kilometers ofParliament Hill indowntown Ottawa and ranges in width from two to ten kilometers. It encircles many of the oldest communities in the City of Ottawa, and covers the same amount of land as the urbanized area of Ottawa that it surrounds.[4]
The Greenbelt was proposed byJacques Gréber in 1950 as part of hismaster plan for Ottawa, and the federal government started expropriating land in 1956.[1] The majority of the lands were purchased by 1966 at an approximate cost ofCA$40 million (in 1966 dollars), of which around40% were acquired throughexpropriation.[4]
Its original purpose included the prevention ofurban sprawl (which was threatening the rural areas surrounding the city), as well as to provide open space for the future development of farms, natural areas and government campuses.[1] At the time, the greenbelt was "intended to circumscribe an area large enough for the accommodation of some 500,000 persons. The inner limit was chosen by considering what area could be economically provided with municipal services."[5]
Growth beyond the 500,000 to 600,000 limit anticipated within the Greenbelt was planned to take place insatellite towns in rural areas beyond it, although these areas were not designated by the master plan. This proposal to build satellite towns was based onEbenezer Howard's 1898 Social Cities scheme and also drew onPatrick Abercrombie's "Greater London Plan", especially in the proposals for the Greenbelt to be implemented by development regulations.[6]
Prior to the completion of the Greber Plan, the Ottawa Area Planning Board (OAPB) was created in 1947 to control unregulatedsuburban expansion. Despite its creation, suburban townships continued to approve low-density subdivisions without municipal services. In an effort to stop low-density suburban expansion, the City of Ottawa successfully annexed rural township lands to the future proposed inside boundary of the Greenbelt in 1948. The rural townships fought the annexation and continued to refuse to zone parts of their land to accommodate a Greenbelt after their loss. After six years of conflict with the rural townships, it became clear that unlike in theGreater London Plan, it would not be possible to establish a Greenbelt using Ontario and Quebec planning legislation alone. As a result, in 1956 theGovernment of Canada decided to buy or expropriate Greenbelt lands as required.[7]
Despite these efforts, research planner H.A. Hossé noted as early as 1960 that there were signs that the Ottawa Greenbelt would not be able to restrain urban sprawl. The surrounding rural townships ofNepean andGloucester retained zoning jurisdiction on lands outside the Greenbelt and encouraged their continuing development to increase municipal tax revenues. The Greenbelt was easily crossed by car in a few minutes, and this did not stop civil servants from seeking more affordable homes outside of it. He concluded that without an active program of planning control by the local municipalities involved, or by the province, growth would continue unabated outside the Greenbelt.[8]
At the same time the Greenbelt was being assembled, developers were purchasing land beyond the belt for future use.[9] The population grew much faster than Gréber had predicted, and his population forecast for the year 2000 was reached as early as 1970. In 1965, the suburb ofKanata was built west of the Greenbelt in the Township of March, and the suburban communities ofOrleans (Gloucester/Cumberland Township) andBarrhaven (Nepean Township) grew up quickly to the east and south of Greenbelt lands, even before the inner suburbs had filled out. Highway development followed this suburban population growth, withHighway 417 toMontreal built through the eastern Greenbelt in 1975 andHighway 416 extended south through the southwestern Greenbelt in 1996.[10]
The rapid population increase encouraged suburban politicians to press for more development outside Greenbelt lands. With the formation of theRegional Municipality of Ottawa–Carleton in 1969, suburban and rural politicians, who had a majority on the regional council used their power to press for urban expansion. Urban boundaries were continually expanded to incorporate further development on former farmland. This general pattern continued following municipal amalgamation in 2001.[9]
The result of these ongoing policies can be seen in local settlement patterns. In 1971, 90 per cent of Ottawa homes were inside the Greenbelt. Seven per cent were in rural areas and only three per cent were in the suburbs. By 2007, only 65 per cent of households were inside the Greenbelt, while suburbs were home to 26 per cent of the city's total households. In that time, 60 per cent of Ottawa's population growth was outside the Greenbelt.[9] From 2005 to 2016 it was typical for there to be roughly twice as many housing starts outside the Greenbelt than inside.[11]
One outcome of this pattern of development outside the Greenbelt is an increased infrastructure burden on the city. While homes inside the Greenbelt pay the full cost of their development, it has been estimated that those in the suburbs receive the equivalent of aCA$5,000 taxpayer subsidy due the gap between development charges and infrastructure costs to the city. Urban planner and geographer Barry Wellar has estimated that this subsidy may be as high asCA$25,000 per house when the long-term maintenance costs of roads, bridges, pipes and transit equipment are factored in.[9]
The City of Ottawa is undergoing[when?] an Official Plan Review which, among other things, examines the need for additional land for urban purposes. It considers whether a discussion of urban land should include the option of some development within the Greenbelt and it is intended that this discussion will feed into the NCC’s review of the Greenbelt Master Plan. All views expressed in [the] White Paper are those of the City of Ottawa and not those of the National Capital Commission[12] which owns and operates the Greenbelt. The City of Ottawa has identified more than 13,700 acres (55 km2) of the Greenbelt, worth about $1.6 billion, that could be developed, and in their view, without damaging its overall integrity.[13] Environment MinisterJim Prentice, opposed development in what he considered an important part of the city's heritage. Prentice vowed to fight any such move.[13]
In 2020, columnist Randall Denley of theOttawa Citizen described the Greenbelt as "a failed attempt to contain growth, not a collection of natural treasures", and supported development within the Greenbelt because "it would give the city the land capacity it requires and deliver all the environmental, transportation and practical benefits that environment groups envision", while Ottawa city staff stated "Expanding urban lands within the Greenbelt is a more efficient use of resources than beyond it."[14]

Throughout its history, the NCC has acted to preserve or enhance the natural environment of Greenbelt lands. In 1961, they entered into a 50 yearforest management agreement with theGovernment of Ontario, which lead to thereforestation of abandoned and marginal farmland. The Pine Grove and Pinhey forests were largely the result of that initiative. In the 1970s, the ecological significance of areas such as theMer Bleue and Stony Swamps were recognized and efforts were taken to protect them. Additional parts of Mer Bleue swamp were acquired and the overall biodiversity of the Greenbelt increased. Walking and ski trails were also created to allow for increased recreational use of these natural areas.[10]
