The Firestone Collection of Canadian Art is a collection of over 1600 works of twentieth-century Canadian art amassed by Ottawa residents O.J. and Isobel Firestone beginning in the 1950s.[1] It is now a public collection owned by the City of Ottawa, and under the custodianship of the Ottawa Art Gallery. There are dedicated gallery and storage spaces at the Ottawa Art Gallery for the Collection. Furthermore, the original marble and brass staircase from the Firestone home[1] is now located as the main feature of the lobby of the new Ottawa Art Gallery building at 50 Mackenzie King Bridge.
