The Canadian Police Information Centre (CPIC) was created in 1966 as an information system for Canadian law enforcement agencies. It is the sole nationwide repository of criminal convictions in Canada. Many employers require a search of CPIC before hiring. However, this system is not foolproof.
Auditor-General reports going back to 2000 have criticized the CPIC system (see para. 7.86) regarding timely delivery of criminal record data.
The most recent Auditor-General report estimates that the RCMP takes an average of 14 months to update an existing English criminal record in CPIC. The French updates take an average of 36 months. The stated goal is updating a record in 24 hours. Unfortunately, reality is an average time of 334 working days (see para. 5.59 & 5.60). For a new criminal record, the average time to process was 27 working days ( see para. 5.60).
If the employer hires someone with a minor criminal record, they may getting someone with a much more serious, but undisclosed, conviction. If the employer hires someone with no criminal record, the employer may be getting someone with an undisclosed conviction for a serious offence.
