The Canadian Light Source is the only synchrotron in Canada and one of the largest scientific infrastructure investments in our country’s history.

Since the start of operations, in 2005, CLS has enabled over 5,000 scientists from 56 Canadian academic institutions and 45 countries, to publish over 6,000 scientific papers, highlighting discoveries in a wide variety of fields, in over 1,000 international scientific collaborations.

From helping in the fight against COVID-19 to creating new cancer-fighting drugs, developing more nutritious and climate-resistant crops and supporting clean-tech and green mining processes, CLS’s infrastructure and experts help researchers solve problems, train the next generation of scientists, and support industries to become more efficient and sustainable.

CLS employs more than 250 people including scientists, engineers, technicians and administrative and business personnel.

The Canada Foundation for Innovation, Natural Sciences and Engineering Research Council, Canadian Institutes of Health Research, the Government of Saskatchewan and the University of Saskatchewan fund our operations.


As a valued Canadian voice for innovation, our leadership and world-class talent achieve excellence in light source services and solutions.


We enable science, learning, and socio-economic benefits through the provision of synchrotron light.


  • Safety: We make safety paramount.
  • Innovation: We expand the boundaries of what is possible.
  • Leadership: We are leaders in light source applications, global science, and organizational excellence.
  • Collaboration: We enable collaboration among users, and sectors across academia, industry, and government.
  • Equity, Diversity, and Inclusion: We are committed to equity, diversity, and inclusion.
  • Accountability: We utilize resources responsibly and hold ourselves to the highest standards of ethics and integrity.

What is a synchrotron light source?

A synchrotron light source produces extremely bright light by using powerful magnets and radio frequency waves to accelerate electrons to nearly the speed of light. This infra-red, ultraviolet and X-ray light is shone down beamlines to experimental stations where scientists can select different parts of the spectrum to "see" the microscopic nature of matter, right down to the level of the atom.

The CLS has enabled scientific advancements in:


COVID-19, cancer, multiple sclerosis, heart disease, HIV, cystic fibrosis, new drug development, antibiotic resistance, malaria, stroke and toxoplasmosis.


Food security, crop development, fertilizers, drought, heat and disease resistant crops, and soil management.

Energy and Environment

Climate change, mine remediation techniques, groundwater contamination, heavy metal contamination in soil, renewable resources, and energy storage and generation.

Advanced Materials

Next generation batteries, high-temperature superconductors, fuel cells, eco-composite materials, solar power, new catalysts for more efficient industrial processes and energy conversion, microdevices, nanotubes, additive manufacturing and tools for the factories of the future.
