Based in Toronto, OAC was founded in 1963 by Ontario's Premier at the time, John Robarts.

[1] OAC plays a vital role in fostering the stability and growth of Ontario's arts community.

An arm's-length agency of the Ministry of Culture, OAC offers more than fifty funding programs for Ontario-based artists and arts organizations.

Grants provide assistance for a specific activity, support for a period of time, or for ongoing operations.

OAC staff manage granting programs, while a 12-member volunteer board of directors oversees the fulfilment of the organization's mandate.
