About the CADC

The Canadian Astronomy Data Centre (CADC) was established in 1986 by the National Research Council of Canada (NRC), through a grant provided by the Canadian Space Agency (CSA), as one of three world-wide distribution centres for astronomical data obtained with the Hubble Space Telescope (HST).

Located at NRC Herzberg in Victoria, BC, the CADC staff consists of professional astronomers and software developers who have developed an abundance of other sophisticated tools to support and enhance the research efforts of Canadian (and international) astronomers. The CADC specializes in data mining, data processing, data distribution and data transferring of very large astronomical datasets.

In 2012, the Canadian Astronomy Data Centre (CADC) delivered over 1.6 million individual files, comprising over 117TB of data and served data to roughly 2000 professional astronomers.


To deliver value to research astronomers through the development and provision of data handling and information technology services. It includes the following mission elements:

  • Ensure that Canadians have access to leading-edge Information Technology facilities to support research and to conduct scientific research relevant to these facilities
  • Create innovative data management systems and services in support of research
  • Contribute to the continuity of the international reciprocal agreements on data sharing in astronomy
  • Transfer and exchange expertise with universities and industry in Canada
