Fair enough. We're all just guessing until we actually hear from someone who gets their card/email/message (specifically someone whose status changed to '20'/'final decision made', post October 1st).
I'll post an update here, if & when I actually get an email/message in the account, or just find the card in the mailbox.
Random/off topic question : When you say 'GCKey' (I see this is many posts by people) - Are you referring to the 'IRCC Secure Acct', where one 'links' the application to check status/receive messages ?
