Qouted from report of Office of the Auditor General of Canada, "Visa Issuing"
2.53 For permanent residence cases, we noted that there was a formal agreement on service standards in the 2006 memorandum of understanding between CIC and the CBSA, which stated that advice will be provided to visa officers within 9 to 18 months. Through our file review, we found that the CBSA had completed its analysis in less than 9 months in 67 percent of the cases and exceeded 18 months in 19 percent of the cases.
2.54 We also reviewed a sample of 10 percent of the 72 permanent residence cases analyzed by the CBSA after CSIS had completed its review for national security concerns. In the cases we examined, we found that CSIS took an average of 34 months to provide its results to the CBSA when there was information requiring further investigation. We noted that the CBSA concurred with the advice provided by CSIS but, on average, it took an additional 9 months to send the advice to the visa officer without adding specific details about the individual.
