Yes, RFV = Ready for Visa email.Then how did you got communication for RFV? Via email? I thought IRCC would reach out via GCKey only.
The weird part about RFV/PPR is that not everyone gets the same thing. Some only get a PPR letter in GCkey (they get "We sent you a message about your application..." over email) and some outland applicants get "Ready for Visa" email. Personally, I wanted RFV over PPR letter as the later would require me to sign-in to GCKey (which isn't too fun).
