As mbr of the CFSPDB let me clarify a few issues raised here. First of all MP involved dom policing will guard service detainees who are incarcerated at their respective guardhouses provided it does not take away from their primary function, which is policing (it depends on the base some will some won't). In Esquimalt sailors run the MP section detention facilities. Secondly, the CFSPDB is not an MP unit as some still believe. The branch got out the jail business a few years ago because no other police force in Canada runs it's own prison. The CFSPDB falls under the CLS. There is a mixture of cbt arms/and MP postions at the prison (half and half) we even have a token sailor. In order for a mbr to be posted to the DB he/she must pass a two week custodian crse. Insofar as the command structure at the DB, (i.e. the Commandant, Chief Disciplinarian and Ops WO) they are MP, this is because MP are more familiar with liability, openness transparency issues than the average cbt arm, however in time this may change.
