Good luck! It is important to keep the full names of the units in mind when researching.

While looking for 53rd Battery, I found 53rd Heavy Anti-Aircraft Regiment.

Not the same thing -
"This Reserve Force regiment originated in Yorkton, Saskatchewan on 1 April 1946, when the '53rd Heavy Anti-Aircraft Regiment, RCA' was authorized to be formed.1 It was redesignated: '53rd Field Regiment, RCA' on 30 July 1954;2 and '53rd Field Artillery Regiment, RCA' on 12 April 1960.3 It was reduced to nil strength and transferred to the Supplementary Order of Battle on 15 October 1968."

I found the fol information on 53rd Battery, but it is not much help because the unit never left Canada, serving as coastal artillery in Nova Scotia:

1ST (HALIFAX-DARTMOUTH) FIELD ARTILLERY REGIMENT, RCA ... On 1 November 1960, it was amalgamated with the '36th Medium Anti-Aircraft Regiment, RCA' (see below) and redesignated the '1st (Halifax-Dartmouth) Field Artillery Regiment, RCA'.<14>

"<footnote> 14. CAO 76-2, Pt 'B', Supp Issue No 682/60. The regiment with its 51st, 52nd and 53rd Batteries amalgamated with the 36th Medium Anti-Aircraft Regiment, RCA, and its 87th, 201st and 205th batteries. The new regiment retained only four batteries, the 53rd and 205th Batteries being absorbed by the regiment as a whole.
