Visit the Brightest Light in Canada

Thank you for your interest in Canadian Light Source tours! The Canadian Light Source is the brightest light in Canada—millions of times brighter than even the sun—used by scientists to get incredibly detailed information about the structural and chemical properties of materials at the molecular level, with work ranging from mine tailing remediation to cancer research and cutting-edge materials development. During your visit, you can explore the full range of exciting science performed here every day.

We offer free public tours on Mondays, Wednesdays and Fridays from 2:30 to 3:30 pm. To reserve a spot on a general public tour, please register below. To book a tour for a group of five or more people, see the bottom of this webpage.
