Steiner,
Pre sec security clearances are one of the processes that move from CFRC to DPM SEC to outside DND to another department, CSIS. They then have to approach other governments to get their information. CSIS also need to colate all the info when they get get it and prepare a report to DND. This takes time and many of the documents that are produced have some enhanced level of security that cannot easily be transmitted electronically. Therefore most replies are on paper and sent by secure mail. It all takes time. Lots of time. The more countries you have been living in the longer it takes.
As advised earlier take the time to prepare for BMQ. The wait is worth it.
Visiting, not calling, your CFRC to remind them of your interest is great. Believe them when they say they don't know when to expect a reply. They can enquire to DPM Sec but getting an answer to where your file is might take a week or so in itself. Also the more questions as to file status cuts the time they, DPM Sec, can devote to processing the files they have.
