Thank you for your interest in the William J. McCallion Planetarium. Unfortunately, we have recently received news that we will not be able to hold shows in the Planetarium due to new Covid-19 restrictions put in place by McMaster and the Department of Physics and Astronomy (see the President's announcement from Dec. 14th here). We hope, at some point in the early New Year, we will be able to do so. This means that we will be unable to book private shows at this time, and we have postponed our scheduled reopening with public shows.

Thank you for your patience and understanding with us as we adapt to new protocols. Should you have any specific inquiries, please reach out to planetarium@physics.mcmaster.ca.


Thank you very much for your interest in the William J. McCallion Planetarium. We are happy to announce that we are in the process of reopening the Planetarium. We are expecting to release a public show schedule with shows starting Wednesdays in January 2022. If you are interested in scheduling a private show with your group, we are excited to already accept your requests. Please get in touch at planetarium@physics.mcmaster.ca if you have any questions or are interested in organizing a show. To ensure that we are conducting our reopening plan in accordance with McMaster's Back to Mac safety guidelines, there are three main steps you will be required to follow to join us in the Planetarium:

1) All visitors to McMaster must wear masks at all times while inside buildings on campus. This includes wearing your mask throughout the entire planetarium show. Presenters will be required to wear masks as well.

2) Visitors to McMaster must provide proof of "second dose of vaccination plus two weeks" before coming to the Planetarium. This can be done by uploading your second dose receipt to the McMaster Safety App by following instructions at this website. This must be done at least one hour prior to coming to campus. In Ontario, an individual is consider fully vaccinated if they have received:
The full series of a COVID-19 vaccine authorized by Health Canada, or any combination of such vaccines, or
One or two doses of a COVID-19 vaccine not authorized by Health Canada, followed by one dose of a COVID-19 mRNA vaccine authorized by Health Canada, or
Three doses of a COVID-19 vaccine not authorized by Health Canada; and
They received their final dose of the COVID-19 vaccine at least 14 days ago.

3) Visitors to McMaster must provide proof that they are feeling well and are cleared to come to campus by completing the Ontario Covid Self-Assessment tool prior to coming to campus. The self-assessment will be checked by our presenters before you are allowed to enter the Planetarium and should be completed within one hour of the start of your show.

Note: We require steps 1, 2, and 3 for anyone age 12 and older, but step 2 is not required for children under 12 (we anticipate this may change to a younger age limit as vaccinations for 5-12 year olds progress).

We appreciate your understanding and flexibility as we continue to adapt to the guidelines laid out by McMaster to ensure a safe reopening. We are privileged that we will soon be able to host you in our space once again. Please direct your concerns and questions to: planetarium@physics.mcmaster.ca.

Sincerely, The McCallion Planetarium team
