In March 2005, the Government of Ontario unveiled the boundaries of a greenbelt around the Greater Toronto Area, a  area stretching from Niagara Falls to Peterborough. The green belt is designed to curb urban sprawl and to preserve valuable natural areas and farmland surrounding the city. However, some types of development including detached single residential, quarries and commercial facilities continue to get approved, exerting pressure and population growth on the Greenbelt. Toronto is among the latest in a line of cities that have implemented growth boundaries of some kind as a method of restricting urban growth, including Ottawa; Montreal; Lexington, Kentucky; Nashville and Knoxville, Tennessee; Minneapolis, Seattle, Greater Vancouver, Miami, Portland, Oregon; Frankfurt; Melbourne; Seoul; and London.
