Moving into corrections from security.

I have recently put in my application to corrections Canada. I have been working as security guard at a shelter for about 2.5 years doing access control related duties. While I'm waiting for my application to go through. I am thinking if I should take on other posts to strengthen my resume and gain more experience to pull from for the interview when it happens.

I work for Paladin security and we cover various sites from hospital to colleges but I just don't know if my experiences is enough.

Any advice and suggestions is appreciated.
