Canada Declassified is a digital repository of government records declassified under the Canadian Access to Information Act. Our holdings span the whole of the Cold War period from 1945 through 1991, the vast majority being government records declassified by the Access to Information and Privacy Division of Library and Archives Canada. The records maintained on this website are open-access and fully available to students and scholars around the world.


  1. Maintain a growing open-source digital repository for the collection and preservation of declassified documents obtained from government and other sources.
  2. Create an interactive web platform of online exhibits, using declassified documents to provide education through historical context.
  3. Hosting and supporting conferences, events, forums, and workshops related to new documentation and what declassified information reveals about key aspects of Canada’s international role.
