I've had this helmet for a few months now and still can't figure out what the QCEA stands for. All I got is Quebec City ? ? . It did come from Quebec, but it could be something entirely different.
It's too bad that better records of all the civil defense units across Canada weren't kept. You never know, all that info may be somewhere waiting to be discovered.
It is a 42 dated CL/C complete with liner and chinstrap.
