then in control of the park, approved constructing commercial and residential developments across the north, east and southwest ends of the park. Recent development The initial phase of the construction of Downsview Park began in 2005. The first step was to regenerate the soil, which had been compacted by more than 50 years of military base use, so that it will again support the lush vegetation that is planned for a very significant portion of the site. A major feature of this initial work was the development of the Canada Forest, which was started with a partnership with Natural Resources Canada and its 2020 Fast Forest initiative. Several residential developers expressed interest in Stanley Greene. Urbancorp was chosen as the first residential developer by Parc Downsview Park after an extensive due diligence process. The first residential development phase at Downsview Park will comprise over 1000 homes. Urbancorp is the largest landowner and developer of residential communities in King West Village and the Queen Street West Triangle area in downtown Toronto. Construction of the new community "Neighbourhood of Downsview Park" is expected to begin in Autumn of 2012. In 2013, Mattamy Homes, Canada's largest homebuilder, entered into a joint partnership with Urbancorp, a real estate developer to begin construction on the first residential community in the park. Local councillor Maria Augimeri said that the development was unlikely to appease angry residents who had expected a park to be developed on the land. In 2014, the City of Toronto once again attempted to acquire control of the park. The federal government rejected the proposal, saying it would not consider transferring responsibility over the park to the city. The Toronto Star obtained a memo that indicating that the government did not want to consider transferring the park because of its immense value. Notable events The property has been the site of several high-profile events, including two Papal visits by Pope John Paul II, in 1984 (while still an active military base) and 2002 (World Youth Day), as well as the Molson Canadian Rocks for Toronto concert in 2003 featuring The Rolling Stones, AC/DC, and many others. The Canadian music festival Edgefest has also called Downsview Park home for the last two years with Linkin Park, Stone Temple Pilots, The Sam Roberts Band, Billy Talent, AFI, Alexisonfire and Metric performing. Edgefest returned to the park in 2011 and will be a featured event again
