The Government of Canada also maintains an urban park in the neighbourhood, known as Downsview Park. The park was formerly used by the Canadian Armed Forces, as CFB Toronto. The park houses several recreational facilities, including practice facilities for the Toronto FC. Downsview Park has also hosted several large public events, including a Papal Mass, attended by 800,000 people on 28 July 2002. The mass was led by Pope John Paul II for World Youth Day. On 30 July 2003, the park also hosted a massive concert known as Molson Canadian Rocks for Toronto. The concert was held in support of the City of Toronto after the 2003 SARS outbreak there.
