Enjoy self-guided Tours of Richmond Hill’s very own national historic site. Explore the Administration Building and the Observatory Dome that houses Canada’s largest telescope. In honour of the RHDDO’s 90th Anniversary, be sure to check out exclusive artifacts from the Dunlap Institute for Astronomy and Astrophysics, University of Toronto on display for a limited time. And be sure to check out our gift shop to purchase a souvenir from your visit.
Please note: This is a self-guided tour that does not include live demonstrations or viewing through the telescope.
Accessibility: As the Observatory and Administration Buildings are historic buildings, they do not meet existing accessibility standards.
