The 50,000 acre Greenbelt is a threatened landscape.

"Together the City of Ottawa and the NCC could do what they like with it." House of Commons Ottawa May 25, 2010 MP Marcel Proulx (Hull-Aylmer, Liberal) "...The Liberal members from the National Capital Region, the member for Ottawa South, the member for Ottawa-Vanier and myself as Liberal members of Parliament, are calling for better protection of the greenbelt.  There are no serious regulations protecting the greenbelt. Together the City of Ottawa and the NCC could do what they like with it. We believe this greenspace must be protected from developers..."
