Visit the Planetarium

Tour the universe with an astronomer!

Explore the night sky over Toronto and travel to the farthest reaches of space and time in a fascinating planetarium show presented by the Dunlap Institute for Astronomy & Astrophysics.
Shows are presented live by an astronomer in the University of Toronto’s 25-seat GeoDome Theater, which is equipped with a new 4K digital projector and sophisticated planetarium software.
It’s your chance to explore the cosmos and have all your cosmic questions answered by a U of T astronomer.

How can we buy tickets?
Individuals, families, and small groups can purchase tickets for one of our pre-scheduled public shows.
Larger groups, such as school classes, Guide and Scout groups, birthday parties, and corporate events should reserve the entire planetarium for a group show at the time of your choosing.
We are not open on a walk-in basis. Please note that we are not the McLaughlin Planetarium, which closed permanently in 1995.

What happens during a show?
Our typical 50-minute show begins with highlights of what’s visible in the night sky on the evening of your show: including constellations, planets, and the Moon. We then take you on a tour through the solar system and beyond. Our upcoming shows are listed below.
If you book the entire planetarium at the group rate, you may select our current-events show, or choose from one of the topics listed in our FAQ (detailed show descriptions are forthcoming).
Can we see the telescopes at the observatory?
Our regularly-scheduled public shows don’t include access to the telescopes or the observatory, only to the planetarium.
Group bookings include optional access to the observatory. If you select this option, your group will spend 30 minutes in the planetarium and 30 minutes at the observatory, seeing the telescopes. If the weather is good, we will set up the telescopes to allow you to view the sky. If the weather is poor, you may choose to skip the observatory portion of your visit and spend the full hour in the planetarium.
Please note that, to accommodate groups of 50 people or more within a single hour, a visit to the observatory is required.

To access the planetarium, enter the building by the entrance on Russell St., go down the stairs, and turn to your right. The planetarium is down the hall and just around the corner.
There is no parking lot at the Astronomy Building, in which the planetarium is located. There is metered parking on the streets around the planetarium, including Russell St. For more information about parking on the University of Toronto campus, please visit
For guests arriving by chartered bus, we suggest that your bus discharge its passengers on one of the side streets around the Astronomy Building, rather than on St. George St. itself, which can be quite busy.
The area around the planetarium is well served by transit. We are less than ten minutes’ walk from either the Queen’s Park subway station and only fifteen minutes from the St. George subway station. We are about two minutes’ walk from the many bus routes along College St. and Spadina Ave.
Please note that the planetarium is not wheelchair accessible–the planetarium is down a short flight of stairs from street level and there is no elevator. For accessible programming, please see our list of Speakers and our upcoming events.

Please note that we are not the McLaughlin Planetarium. That building is still standing, but has not operated as a planetarium since 1995.
