I'm not a member of the Air Cell, but my understanding from what I've been told from members of the unit (and someone with their maroon can correct me if I am wrong), is that you will need the following to get your maroon beret.
You will need to be MOC qualified before taking the CF Basic Para course, which means you'll need to be in roughly a year before you can apply for the course.
You will then need to do the CF Basic Para course, which is a rigorous 3 week course held at the Canadian Parachute Centre at CFB Trenton, Ontario... (to be selected for the course you must first pass the pre-selection testing done at the home unit, and there are many applicants, and usually not enough spots for all those applying, its very competitive, so keep your fitness level up)
Once completing the course, you can apply for your maroon when you get back to unit, you will have to complete the EPL (Expected? Performance Level) fitness test, do refresher training, and there is some requirements for white wings, which someone else can fill you on as I do not know the specifics of that since I'm not a jumper.
If I've made any errors, I'm sure someone can point them out, but that is an accurate outline of what is required, from what I've gotten directly from the horse's mouth. (MBRS of the Coy)
Good luck finishing the recruiting process, it will pay off in the end.
