Royal Canadian School of Artillery.
1946 - 1960
"After the departure of the maintenance unit, most of the base was taken over by the Army for use as the
Royal Canadian School of Artillery (Anti-Aircraft) (RCSA(A.A.))."
"The 1st Light Anti-Aircraft Regiment RCA was formed in October 1953. It consisted of a HQ and the 2nd and 3rd LAA Batteries, and it was located with the RCSA (Anti-Aircraft) at
Picton, Ontario. "
"With the
closure of the 1st LAA Regiment and The RCAS (AA) in Picton in 1960, the only remaining school of artillery was at Shilo."
