I mean, there would certainly be some. Pay and comp: while base pay may not be a whole ton lower, it wouldn’t have to come with a 25 years and out unreduced pension. Other HR related institutional costs like CAF provision of primary healthcare wouldn’t have to be borne. Hiring people to work in Canada without the same mobility expectations would probably be easier; in some respects.probably it would become a farm team for uniformed SF recruiting. Most of the advantages would probably be economic efficiency ones.
Against this there are definitely plenty of disadvantages; a larger pool of OFP deployable SF gives CAF tons more flexibility. It’s costlier and less efficient, but operationally almost certainly better.
I’m not taking a strongly considered position either way; people closer to the problem would be better for that. Though personally I would lean to give CAF the PYs and funding. I’m just saying if CAF/DND wanted civilian armed security with long guns and good kit and training, it’s definitely doable.
I’ve seen SF spoken of mostly in the RCAF context, but will they play a role at navy, army, or CANSOF force protection?
