The Background and Political Climate

  • BackgroundThis section introduces the philosophy of why this Web site was created and to whom it is dedicated.
  • In The BeginningThe beginning of the Pinetree Line.
  • Slide ShowThis series of slides is reproduced from an official presentation from the Cold War era. It clearly shows the overwhelming concern about nuclear attack and stresses the kind of political and military climate that the thousands of personnel lived with while serving on the Pinetree Line.
  • ReportsThis section offers an assortment of monthly progress reports which originated within the Pinetree Project Office covering the Pinetree Line during the years 1952-55. We have also obtained a small number of Canadian External Relations reports which pertain to the Pinetree Line or Contintental Defence during the years 1952-55.

If you have information that can fill in the gaps please consider contributing to this site.
