Possibly connected to the Civil Aeronautics Authority ?

The Civilian Pilot Training Program became the War Training Service (WTS), or Civil Aeronautics Authority (CAA) War Training Service and, from 1942 to 1944, served primarily as the screening program for potential pilot candidates. Students still attended classes at colleges and universities and flight training was still conducted by private flight schools, but all WTS graduates were required to sign a contract agreeing to enter the military following graduation.

The Maple Leaf would suggest the first letter C is for Canadian or Canada. There is nothing military in the actual woman in the photo at all.
