Public Lecture Series

Perimeter Institute brings great thinkers from around the world to Canada to share their ideas on a wide variety cutting-edge subjects. Each event is tailored for the general public and everyone is welcome to attend. No mathematical or physics knowledge is necessary or assumed, but curiosity is required. 

Upcoming Public Lectures

Information on each lecture will become available by the Friday prior to ticket availability. To receive advance notice, sign up for the Public Lecture emails.

The Perimeter Public Lecture Series was created for the purpose of sharing the power and wonder of science with the world. The series has included talks from Nobel Laureates, Fields Medal recipients, and some of the world’s most renowned scientists, including Stephen Hawking, Leonard Susskind, Ed Witten, Jocelyn Bell Burnell, Nima Arkani-Hamed, Jill Tarter, Roger Penrose, Sara Seager, and many more.

Each lecture has a live audience, with free tickets on a first-come-first-served basis. If you aren’t able to get tickets to attend in person, you can still enjoy the lecture on the big screen in the comfort of Perimeter's Black Hole Bistro. Each lecture is also webcast live for free on our YouTube channel, and all talks are available on-demand within 24 hours of the live webcast (watch previous talks here).


Attendance to the lecture is free, but advance tickets are required. Due to the overwhelming response to past lectures, tickets will be honoured until 6:45 pm only. If you have not arrived by 6:45 pm, your reservation may be filled by guests in our waiting line, and you may be asked to join the end of the waiting line.


There will be a waiting line for last-minute cancelled (or "no show") seats on the night of the lecture. Doors open at 5:30 pm. Come to Perimeter and pick up a waiting line chit at the Waiting Line sign. An announcement will be made in the Bistro at 6:45 pm if theatre seats are available. Note: you must arrive in person to be part of the waiting line and be in the Bistro when the waiting line announcement is made.


Everyone who comes to Perimeter will be able to participate in the lecture. The public lecture will be simulcast in the licensed comfort of the Black Hole Bistro for any members of the waiting line who are not able to get a theatre seat.
