The old (green) uniforms came out because of the unification of the CF. Since cadets is funded by DND, they decided that the cadets should follow suit with the head dress being the only difference. Even before that the cadets' (Sea anyway, never saw the old Air or Army uniforms) uniforms were practically indistinguishable from the CF uniforms. If any of you have seen the Sea Cadets in ceremonial blues or whites, well, that used to be their regular uniform.
So, if history has taught us anything, unless you see a change in our uniforms, you probably won't see one in yours. As for the flashes, that is a unit budget thing. Same thing with cap tallies. Some of you who have gone to Borden may have noticed the guppies (really a term of endearment as I used to be one) with tallies that had the RCSCC long form and some with their corps names. All in the budget.
Hutch, the uniform you describe sounds very much like the ones that the RMC students wear. Maybe someone spent some time at HMCS Ontario and got the wrong idea from the RMC cadets that were spending the summer there. If after 2 yrs you haven't heard anything I wouldn't worry. BTW, when I was a cadet we were told we were getting the new (elemental) uniforms. It took 5 years from that rumour until it actually happened.
