RCASC, Stock Clerk, Ralph Stanley MADDICK

[Terry]

I am trying to trace the history/service of a Ralph Stanley MADDICK who was a Stock Clerk in the RCASC (Royal Canadian Army Service Corps) during WWII.
I know his Regimental Number was: B 8847.
Anybody any suggestions on how to go about this?
I do not know his date of birth, marriage or death.
