In terms of education they want you to have atleast 2 years of post secondary,preferably in law,some other small certs like a firearms license,cpr etc. In terms of power they have, I would say they are very similiar to the RCMP/Canadian Coast Guard as they are all federally ran, and regulated. Security guards just have a card that says they are security officers and have passed a clearance. Peace officers are a bit higher and go through a bit training/POPAT tests from my understand.
Here is a link I hope you find useful.
