What is La Macaza Institution, the facility he was quietly moved to? Here’s what we know about Paul Bernardo, what the difference is between a medium- and a maximum-security prison, and how federal corrections determines which level offenders should be placed in. La Macaza Institution is built on an open-campus model in Quebec, according to CSC. La Macaza Institution specializes in providing treatment to sex offenders and almost two-thirds of the inmates held there have been convicted of a sexual offence. The offender’s security level is based on how they’ll adjust to the institution, the risk of escape and public safety.
