I uploaded my PCC through GCKEY account on June 18. How long approximately does it take for them to review this?Depends on the nature of your documents.
If it can be uploaded online, it should not take too long. However, if it’s provided by other party like police info check. It’s pretty time consuming. In my case, I needed to request the police check from the country of my origin. It took me sometime to complete that and confirmed with IRCC they have been received.
It took me around 40 days. Please be reminded that the ADR need to be received by IRCC within 60 days.
