Booking Information
Seeing or Booking a Show

Public Shows (for individuals)
Dates:Wednesdays; the current schedule can be found here
Time:7:00pm, 8:15pm
Cost:$7/person; HST included; payable at the door; cash only (exact change appreciated)
Please note that if you are late, your reserved tickets may be given away to those without reservations. You can reserve your tickets and manage your reservations here. Tickets may be available at the door, but this is not guaranteed. If a show is sold out you can choose to be added to the waiting list, and you will be notified if seats become available. We have found that the planetarium shows are generally not suitable for very young children (younger than 6 years old) due to the nature of shows. The special acoustics of the domed planetarium also means that we ask visitors to not talk unless asking a question during the show, which is challenging to do for some youngsters for the length of a one-hour show. We also ask parents of older children to consider these potential problems. We encourage those with younger children (under 12 years) to attend the 7 p.m. show only if there are multiple showings in one evening. All children under 16 must be accompanied by an adult. If disruptive noises do occur, the presenter will ask those responsible to leave. We regret we accept no responsibility for a customer having to leave, whatever ther reason: there is no refund, no re-entry, and no transfer to another show.
