My timeline.
22 November: Telephone landing--- same day I received an e-mail to submit Completion of Confirmation of Permanent Resident Document.
Note: I signed the documents, both COPR, during the interview. However, I was told NOT to date any of the copies, the reason is that they will date them when they receive them from me, and date under my signature will be also dated by them, only my signature is required. It seems on the day they sign them, you are officially permanent resident. You will send both copies of COPR (both will be signed), and they will return your copy and will keep their own copy.
23 November: I sent the signed COPR forms (note that I did not include xpost envelope, and it looks they deliver my copy at their own expense).
27 November: Delivered.
28 November: I could link my PR card on my existing CIC account, and it looks my PR is approved on 28th November

And I used only name, surname, date, and place of birth when selecting on the menu in order to link PR card processing to my CIC account.
I think they will also send my copy of validated COPR soon. With the validated COPR form (signed and dated, and copy of me sent by them), I can apply for SIN number, and health care card.
Thank you,
