This year we’re trying something different. We are posting blocks of tickets throughout the summer and adding additional programs where possible. The first block of tickets sold out very quickly. Now, tickets for programs in July and August can be found on the Schedule page.

We hope this year’s phased ticket release will give more people the opportunity to visit the largest telescope in Canada and enjoy the award-winning public programs offered by the Toronto Centre of the Royal Astronomical Society of Canada. 

The David Dunlap Observatory is located at 123 Hillsview Drive, off Bayview Avenue north of 16th Avenue in Richmond Hill, Ontario. 

Join us for an evening of telescope observing, space crafts, space talks and tours. On program nights we check out a wide variety of celestial objects, including the Moon, Jupiter, Mars, Saturn and more.
