Hanno,
I attempted to find some period Canadian definitions for the various packing methods, but I have not been successful so far.
In the absence of formal definitions of the packing methods, I did find some early documents that may be of interest.
It seems the initial shipments of CMPs were a combination of S.K.D. and Complete - Unboxed. These were followed by C.K.D shipments, followed by an urgent request to revert to S.K.D.
The following images are from microfilm C-5142, images 429, 430, 456, and 457, and 238 :
