That's fine and dandy but what the cops can access in CPIC is quite different from what the general public can find out. And what the general public can find out is what the original poster was asking about.
There are various levels of access. A standard criminal background check is low level access. I believe (but I could be wrong) that a background check for vulnerable sectors (i.e., child care employment) is a higher level search. And for jobs in secure industries (e.g., working at a nuclear plant) the level is one of the highest and involves the RCMP. The OPP normally administers CPIC.
So just b/c a cop enters something into the CPIC database doesn't mean it's accessible to just anyone. And for what it's worth, I don't believe that anything a cop enter goes into the CPIC database. It may go into the local police force's database (and there is a difference), but I doubt it goes into CPIC. Why? For the simple reason that it opens up a whole can of worms that defense lawyers can rip into since a cop could enter anything, whether it's been proven or not. I may be wrong, but I really
really doubt cops can enter anything they want.
