Gallery Arcturus, Contemporary art museum in downtown Toronto, Canada

Gallery Arcturus occupies a 10,000-square-foot heritage building at 80 Gerrard Street East, built in 1858 in the Georgian Revival style and sometimes called the Green House. Its nine exhibit areas include the Genesis West and East galleries, Up North, Collage, Photographic and Ascending galleries, plus a Library, Drawing Room and Dark Room. The Ascending Gallery runs from the first to the fourth floor; the Photographic Gallery overlooks Gerrard Street.

Gallery Arcturus was founded in 1994 by the Foundation for the Study of Objective Art as a non-profit center. Since its opening, the venue has developed into a platform for contemporary artistic practice in Toronto.

The gallery's name refers to Arcturus, a star in the constellation Boötes. Its nine exhibition areas carry names tied to their contents: Up North holds landscape paintings and sculptures of northern Canada, and the Library displays Floyd Kuptana sculptures alongside artworks and books by E.J. Gold. Shows usually debut every six to eight weeks.

The museum offers free admission to all visitors and maintains a specialized art library with resources on art history and theory. This makes it accessible for anyone who wants to explore or learn more about contemporary artistic practice.

The gallery occupies a heritage building at 80 Gerrard Street East, built in 1858 in the Georgian Revival style and possibly known as the Green House. The Canadian Group of Seven painter Lawren Harris depicted it in his 1912 work Houses, Gerrard Street, Toronto, now held by the McMichael Canadian Art Collection.
