Welcome to the Pinetree Line!

  • In The Beginning The beginning of the Pinetree Line.
  • Slide Show This 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.
  • Reports This 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.
