In spite of pressure from realtors and home builders to decrease the size of the Greenbelt to allow for expansion of housing developments, Premier Kathleen Wynne told the news media that the 27 April 2017 Provincial Budget will not diminish the protected lands. "We're committed to growing the Greenbelt not shrinking the Greenbelt," she explained. According to the Neptis Foundation (a publisher of nonpartisan research on urban regions), there are roughly 45,000 acres still available for development in the GTHA, adequate until at least 2031.
