The CLS is not currently offering in-person tours. We will update this page and our social media channels when our programming re-opens.

Virtual Tour

Welcome to the home of our virtual tour, we are so happy to have you!

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.

Navigation tips and tricks are found below the tour, but feel free to jump right in and explore.

The highlight reel is found at the bottom of the tour, outlined in red. This can be accessed via the V, outlined in yellow.


You can navigate the space with your mouse or arrow keys. Navigation tips can be brought up at any time by clicking "Help" in the lower right hand corner. The "More Help" tab that appears in this window will also provide detailed information about the features available in the tour.

Our space is quite large, so you probably won't make it though everything in one sitting! To jump to different spaces in the facility, you can use the highlight reel found at the bottom of the frame.

The tour begins at the electron gun, where the electrons that produce our bright light begin their journey. You can jump ahead to the scientific facilities in the Highlight Reel, which begin at Mid-IR.

Colour Codes

Our tour uses several colour codes to help you find the information you'll find most interesting.

▶ Purple tags share the science enabled by the Canadian Light Source.

▶ Green tags explain the scientific equipment.

▶ Blue tags are for fun facts.

▶ Orange tags provide directional instructions.

NOTE: This tour was recorded while our facility was in maintenance mode, providing us with access to parts of the machine that are usually closed to staff and visitors alike. This also means that some areas are under construction, and we hope to update these areas in the near future.

Tour Posters

We have many posters on the walls of the CLS for visitors to read during in-person tours. Want to read them in detail? Find them all here:
