I think what you have is a cravat from the 1970s or the early 1980s when this item of dress was in vogue with the CF. The wear an issue of these cravats was very much the call of the various branches and regiments and this item could well have been unit procured to wear with combats. I have looked through a couple of references on the 1SSF and I have yet to find a photograph of a Forceman wearing a cravat in WWII.
As well, I have attached images of the following pieces of camouflage: a WWII US Mosquito Net, a 1960s Parachute and the 1990s Canadian Garrison Dress. Note that your camouflage does not seem to match any of these patterns.
