I have the same...but can't open and see an update... I had the same a month ago, but there were no updates on my profile...I feel like it's just a system's error...
It seems i have a GU in my GCKEY, but I cannot click on it to see the status, the website just keep loading it, I also check ECAS it still said IN PROCESS. not sure whether it is a real GU or just a system error.
Yes, it is nothing...my profile didn't change since that update, the same happened 1,5 months ago and an agent told it's a system's error as she doesn't see any update in my account.
1. Just got $170 refund from IRCC (info: Citizenship & IMM ON-L). I guess this is a Biometric service fee (85 x 2) for me and my wife - they use my previous biometric when i applied Study visa in 2016 and my profile on gckey has a biometric number. So I can assume that this is biometric excemption due to covid, can't I ?
2. Also have a ghost update last night, as I research on google, "Background Check changes to “Your application is in progress. We will send you a message when we start your background check". How long will the background check process be? Hopefully this is a good sign.
