The Cold War Pinetree Radar Line Station
Moosonee Air Force BaseLocated near Wabusk Ave. and Mistic Blvd.
"During the early years of the Cold War, three massive radar lines were constructed across the north: the Distant Early Warning (DEW) line, the Mid-Canada line, and the Pinetree line. The goal of the radar lines was to monitor Soviet plane traffic across the Arctic in order to intercept planes, armed with atomic weapons, which were intended (presumably) to destroy North American cities.
The town site of Moosonee experienced little development until the Temiskaming and Northern Ontario Railway (T. & N.O.) connected the town to Cochrane in 1932. By the mid 1950’s, Moosonee had become a shipping centre for more northerly Mid-Canada radar base sites, like Fort Albany and Winisk. Several Mid-Canada Line (MCL) articles referred to Moosonee as a Cold War construction and shipping center. For example, in the 1958 Roundel, Flying Officer S. G. French described the establishment of “marshalling areas at ends-of-steel." In Ontario, this meant Moosonee as the furthest north railway line or “end-of-steel.” French then described how Moosonee, became “a new main base of operations.” He emphasized the role of Moosonee as a central operations base by noting that when work was completed much further north, helicopters returned to Moosonee. French also described winter tractor train operations. He wrote that “During the winter of 1955-56 about 11,000 tons of materials were moved …by tractor train. At their peak, these trains running out of Gillam, Manitoba and Moosonee, Ontario used over 400 sleds and over 40 heavy tractors.” Clearly, Moosonee was part of Cold War activities long before it hosted a radar base.

By 1961, Moosonee had its own military base–a Royal Canadian Air Force (RCAF) Pinetree radar base known as ‘Sasakipao’. This base, constructed only a mile or so from downtown Moosonee, operated from 1961 to 1975 (see “Air Photo of Moosonee Pinetree Radar Base, 1962”). It became the home for 150 RCAF officers and airmen, their spouses and their dependent children. It also became the workplace for approximately 60 civilian employees from Moosonee."
