Yearbook Update 1941

I've separated 1941 into the two units: 15th (Vancouver) Coast Brigade RCA CASF and 15th (Vancouver) Coast Brigade RCA NPAM with some new War Diary entries into the NPAM unit.
Some interesting historic trivia to think about:
"Notification was received that henceforward the expression, “N.P.A.M.” would be discontinued, and the army would be divided into the “Active” and “Reserve” forces."
Does this mean that the units will now be known as 15th (Vancouver) Coast Brigade RCA AF and 15th (Vancouver) Coast Brigade RCA RF?
"2/Lt Graham Frederick Blythe and .... were appointed to the Regiment effective 8 Mar 41."
Graham Blyth went on to command the 43rd Medium Anti-Aircraft Regiment RCA; then Honorary Lieutenant Colonel and Honorary Colonel of 15th Field Artillery Regiment RCA. 
"The future Capt. J.A. Hobday enlisted as a Gunner 2 Apr 41."
What does that mean? Who is this Hobday fellow?
