RCAF Station Aylmer was a Royal Canadian Air Force training base that was established on July 3, 1941 just north-east of Aylmer, Ontario, Canada. It was one of many built across Canada under the British Commonwealth Air Training Plan during World War II.
The first school at Aylmer was No. 14 Service Flying Training School (SFTS). Pilot trainees flew North American Harvards in the advanced training role and for a brief time (1941-42) used the North American Yale as an intermediate trainer. No. 14 SFTS moved to Kingston in August 1944.
Other schools located at Aylmer include the WD Service Police School (1942), No. 1 Flight Engineers' School (July 1, 1944 - March 31, 1945), the RCAF Technical and Engineering School (later redesignated No. 1 Technical Training School or TTS) (April 1945 - May 1955), an Academic Training School (ATS) (May 1949 - Oct. 1950), a composite training school (No. 2 KTS), No. 11 Examination Unit (Sept. 1951 - Nov. 1952), the Aeronautical Engineering School (June 1952 - Nov. 1953), the RCAF GCA (Ground Control Approach) School (1953 - 1957), the RCAF Fire-Fighting School (1951 - 1961), and the Support Services School (1960).
No. 2 Manning Depot and No. 1 Personnel Selection Unit (PSU) were located at Aylmer from 1949 - 1950.
The station closed in 1961 and the Ontario Police College eventually took over the facilities.
All that remains from the RCAF days are 2 hangars, one re-sided in metal and the other bricked over, the rapidly crumbling airfield and the taxi area, which is now used as part of the police vehicle driver training track.
At the entrance the Ontario Police College property sits a memorial to the former RCAF station.
