With a collection of more than 80,000 works of art, the AGO is among the most distinguished art museums in North America. From the vast body of Group of Seven and signature Canadian works to the African art gallery, from cutting-edge contemporary art to Peter Paul Rubens’s masterpiece The Massacre of The Innocents, the AGO offers an incredible art experience with each visit. In 2002 Ken Thomson’s generous gift of 2,000 remarkable works of Canadian and European art inspired Transformation AGO, an innovative architectural expansion by world-renowned architect Frank Gehry that in 2008 resulted in one of the most critically acclaimed architectural achievements in North America.
