There were separate buildings for two primary schools: (Hillside Schools - Innobis Confidimus: In Us Trust), a recreation centre with a bowling alley, theatre, gymnasium and swimming pool (No.8), a ‘twinned two denomination’ chapel (No.17), the sports fields, an outdoor skating rink, a 25-yard shooting range and a single line ski tow.

adjoining radar towers of similar construction, and twenty-five associated service buildings. The ‘search’ radar, with a range 75–100 km, was installed on the roof of the ‘main’ operations building and on two adjacent towers were the height finder, and a back-up ‘search’. Recurring wind damage, and winter weather, led to the housing of the radars inside 15-metre diameter inflated rubber domes.

line of radar stations, across southern Canada, to enhance warning of ‘air attack’ and for the direction of fighter interceptors. Given the estimated costs in construction, maintenance and personnel, it was agreed Canada would focus on priorities in southern Ontario and Quebec, with the United States on stations in Western and Atlantic Canada.

From 1963, the station counting 185 military personnel and 89 civilians, No.13 AC&W Radar Squadron was disbanded on 1 April 1964, with a downsizing of RCAF Air Defence Command AC&W Radar Squadrons, and another re-alignment of the NORAD system. 284:

Coming to St Sylvestre, in the early days of its operations, were a select group of ‘RCAF Auxiliary’ radar and fighter control operators from No.2450 AC&W Squadron (Auxiliary) in Sherbrooke Quebec. Covering staffing shortfalls, in maintaining 24/7 operations, these volunteers were notably active

Canada's early ‘Continental Radar Defence System’ stations, with both early warning detection and aircraft control functions, were initially identified with - Radio Detachments (RD) designations, they changing to - Radio Units (RU) in 1944, and later - Radio Stations (RS).

Plans for the Pinetree Line were first considered, as early as May 1946, as Canada worked with the United States to consider cooperative continental defence planning, against limited long-range bomber air attacks. In 1949, the United States Congress agreed to 'shared' financing the construction of a

Built by H.J. O'Connell Company (Montreal), like all PINETREE Line stations, St Sylvestre was a self-contained community, with sixty ‘private married quarters’, initially five single and fifty-five double-width (single and two story) family homes, with 30 PMQs added in 1961, in a mobile home park,

Throughout its short ten-year life, St.-Sylvestre had four Commanding Officers: 1953–1954 W/C JD Mitchner DFC Bar, of Saskatoon, Saskatchewan; 1954–1957 W/C LPJ Dupuis DFC, of Ottawa, Ontario; 1957–1961 W/C JHL Lecomte DFC CdeG, of St. Theodore d’Acton, Quebec; and 1961–1964 W/C EW Smith DSO, of

RCAF Station St. Sylvestre, Site C-6, was a Group II PINETREE Medium Radar Site, whose essential services, operations, with staffing, and their associated costs were shared with the USAF, until June 1961. As a Type C Station, it consisted of an Operations Main Building, of RCAF design, with two
