Yikes...
I've sent a PM to Watchdog-81 to look at this train-wreck and offer some advice ref the MPO world if he so wishes...
But in the meantime:
MedTech:
In the MP world, "Administrative things" do NOT include serious crimes investigations or the provision of anything other than "Administrative things". Although MPO do fill a small number of investigative positions, the vast majority of MPO sit at a desk doing "Administrative things"...at least that's what I think they do in their offices with the doors closed.
Most police work (of all levels of seriousness) is conducted by MP of the rank of Sgt and below. Also, Canadian doctrine defines more than officers as "leaders" with leadership roles, hence the Primary Leadership Qualification, Intermediate Leadership Qualification and Advanced Leadership Qualification...see a theme here? Telling someone they need to be an officer to pursue a leadership role isn't on.

The email in your profile indicates you are in Fredericton. If so, CFB Gagetown is just down the road. If you haven't already done so, call 422-2000 and ask for the Military Police. Explain that you are interested in a career as a MPO and ask to go out and visit the Detachment. The MPO and MP there should be more than happy to show you around, sit down and talk with you and answer any questions you may have about the Branch.
From what I can see, what you're doing should put you in competition with others who apply and campus cop experience is equivalent to any other security position, at least in my professional opinion. Unfortunately there is usually an extremely small number of applicants accepted off the street each year so expect a tough fight.
