Canadian Forces Station Foymount (CFS Foymount) was a military radar station in Foymount, Ontario, Canada, (part of Bonnechere Valley). RCAF Station Foymount was opened in 1952 as part of the Pinetree Line of NORAD radar stations. The radar itself was situated at the top of a 523 metre hill, one of the highest points in southern Ontario. The main lodger unit was No. 32 Aircraft Control and Warning Squadron, later renamed No. 32 Radar Squadron when the Semi Automatic Ground Environment system was implemented in 1961.[2]

In 1967, RCAF Station Foymount was renamed CFS Foymount with the unification of the Canadian Forces. A few years later, the base was declared redundant; radars at CFS Falconbridge and CFS Lac St. Denis were deemed sufficiently powerful to monitor Foymount's coverage area. The station was closed in 1974 and sold to private interests. Some of the residential and service buildings at the base are still in use.
