Royal Canadian Navy : HMCS Protector II, 1943.
Group of 23 men, almost certainly from HMCS Protector II. Ronald Edward Gillis is in the front row, 2nd from left.
The only visible trade badges are three for Signalmen, so this may be a departmental photo. The wooden decking seems to be the same as in the photo below.
Photo is titled "Anson Division / HMCS Protector II, March, 1943".
Ronald Edward Gillis is in the front row, 2nd to the right of the Chief Petty Officer.
