McCormick Playground Arena is the official name of the building as a tribute to the McCormick Playground. Opened on July 1, 1911, the McCormick Playground at 163 Brock Avenue was Toronto’s largest children’s playground until 1963 when it became known as McCormick Park at 66 Sheridan Avenue. McCormick Playground was the namesake of Mary Virginia McCormick, a wealthy Toronto resident who donated generously to the Toronto Playgrounds Association.

Mary Virginia McCormick (1861-1941) of Chicago was a philanthropist whose father, Cyrus Hall McCormick (1809-1884), founded the McCormick Harvesting Machine Company in 1847. She was a resident of Toronto from 1908 to 1924 who donated a total of $25,000 to the Toronto Playgrounds Association to build the largest municipal children’s playground with a community recreation centre in Toronto on the property of the former Grand National Rink.

Mary Virginia McCormick (1861-1941) visited Toronto in 1904 and her family bought the Oaklands estate at 131 Farnham Avenue as her residency in Canada from the family of Senator John Macdonald (1824-1890) in 1905. Receptions for charities were held inside her home and elaborate springtime garden parties for families were held annually on the grounds of the estate. The property was sold to the Brothers of the Christian Schools in 1931 and became De La Salle College “Oaklands.”
