The Killam Annual Lectures
Each year the Canada Council for the Arts awards five Killam Prizes in five disciplines: Natural Sciences, Humanities, Health Sciences, Social Sciences and Engineering. These Laureates then travelled to a "Killam" university at some point during the calendar year to give a public lecture.
Starting in 2014, the lectures have been moderated TED-style talks. They were very informative and engaging, and since 2015, they were taking place at the laureates "home" universities!
Although there were no lectures after 2016, you can view the previous lectures here: View Previous Lectures (click the thumbnails to enlarge the posters).
