Please join us in the planetarium for a show presented live by a University of Toronto astronomer. Our full schedule of shows is listed below. Show dates and topics vary. Shows are open to all ages, but parents of very young children (under 5 years old) should use their discretion in deciding whether your kids will be comfortable in a dark room for 50 minutes.

Admission for all regular shows is $10 per person (all ages) if pre-purchased online. Rush tickets may be available at the door for $10 per person (all ages, cash only). Links to pre-purchase tickets for each show are available on the description page for that show, accessible via the “Read more” links below.

Please arrive 15 minutes before your show. To ensure the best experience for guests during shows, the doors to the planetarium will be closed and locked to outside entry for the duration of each show. If you arrive after the scheduled start time of your show, you will not be able to enter the planetarium and your ticket will not be refunded or transferred to another show. For the first show on each evening, the doors will open 15 minutes prior to the show. For subsequent shows, doors will open 5 minutes prior to the show.
