"Prescribed by the CF" means simply that the wings are legitimate military parachute wings.
Badges, such as the
Dutch Jump Wing are legit.
Badges from
Civilian parachute clubs are not.
Badges from certain
Walter Mitty-esque organizations : are not.
The Dutch basic para has been contracted (Alternate Service Delivery) to a civilian skydiving club. If a graduate is posted subsequently to a jump line serial, such as the Royal Netherlands' Marines or 11 Airmobile Brigade, the gaining unit will then teach real paratrooping skills, such as rigging & jumping weapons, ruck, etc. But it is a NATO-approved jump qualification (which may be a comment on NATO's decline).
All those Dress Regs Mike posted can be distilled down to "you can wear them when you're serving in that foreign country and if you're officially hosting/working with military pers from that country" - - may not come up too often for an Ontario-based Reserve Pte.
Because their basic is now just a civie skydiving course - - "go out the door, turn left" - - that, as mentioned, anyone can simply buy the qualification, there are a LOT of posers out there now padding their ninja-sniper qualifications with
real jump wings. Having the wings may not get you the response you were hoping for.
I'm just sayin'......
