are used regularly for other exhibitions such as home shows, industrial exhibitions and conventions, including political conventions. Since 1967, when the Ottawa Auditorium was demolished, Lansdowne Park has become a site of musical concerts, both inside the Arena at TD Place and outside on the Stadium field. Although the Canadian Tire Centre arena was built in 1996 and hosts the largest indoor concerts in Ottawa, the Arena at TD Place continues to host musical concerts. Redevelopment In September 2007, cracks were found in Frank Clair Stadium, necessitating the demolition of a portion of its south-side stands. The City of Ottawa subsequently started a review to redevelop Lansdowne Park. A group of Ottawa businessmen, known as the Ottawa Sports and Entertainment Group (OSEG), were awarded a new Canadian Football League franchise (now the Ottawa Redblacks) in March 2008, contingent on securing a stadium in which to play. OSEG proposed a public-private partnership with the city to rebuild the stadium and redevelop the grounds with residential and commercial uses to finance the reconstruction and annual upkeep of the site. Ottawa City Council decided to enter into a partnership with the OSEG group and abandoned its own review. The redevelopment plan split into two components after the City rejected the portion of the OSEG proposal regarding the lands bordering the Rideau Canal. OSEG was assigned the precinct around the stadium and along Bank Street, while a design competition was held for an urban park to be located along the canal. The OSEG plan envisions two towers along Bank Street, a new set of grandstands at the football stadium and a new residential and commercial precinct to the north of the stadium. The new greenspace along the Rideau Canal frontage is intended as a new front lawn for Lansdowne. The estimated cost to the city for the stadium renovation and its share of the parking development is $129.3 million. OSEG's funding of the commercial redevelopment and its share of the parking is $118 million. The urban park is estimated to cost $35 million and $8.5 million has been spent for a new trade show and exhibition hall built near Ottawa airport, to replace the existing space at Lansdowne. The total estimated cost is $290.8 million, $172.8 million coming from the city. The city retains ownership of the site, leasing the commercial and retail component to pay off the debt under a revenue-sharing formula with
