Yes, you are correct. The BGC (Background Check & Security Screening) is comprised of two parts:
- Criminality Check: This is a check of your criminal history. It is done to ensure that you have not been convicted of any crimes that would make you inadmissible to Canada.
- Security Screening: This is a check of your security status. It is done to ensure that you are not a security threat to Canada.
The BGC status will change twice during the application process. The first change will occur when the criminality check is in progress. This is usually early in the application process. The status will then change to "Not Applicable" once the criminality check has been completed.
The second change will occur when the security screening is in progress. This is usually towards the end of the application process. The status will then change to "Completed" once the security screening has been completed.
Only after both, the criminality and security checks are done, the BGC is conclusively passed.
I hope this information is helpful.
