It appears that where was a regimental history of the 2nd Fd Regt. RCA published soon after the end of the war in Utrecht. There is reference to it in “The Gunners of Canada Vol II 1919 -1967” by Colonel G. W. L. Nicholson as followers
“Regimental History: 2nd Canadian Field Regiment R.C.A. (Utrecht, n.d.)”
The current unit was only reconstituted with 7th, 50th and 66th batteries in 1966, following the disbanding of the 2nd Medium Regiment in 1965. I was a member of 2Fd from 1971 to 1976. At that time the only link with its past history was in its name only. There was no regimental association or veterans groups that I know of. If you want to contact the Regiment their address is:
2 Field Regiment
Royal Canadian artillery
4185 Cote des Neiges Rd
Montreal, Quebec
Canada
H3H 1X2
The 10 field battery, which was part of 2Fd Regiment during WWII, has a web site and an association. The link to their site is:

You can also try to contact the RCA museum in Shilo Manitoba ;

Good luck.
