I completed by landing via phone on 13th Dec and mailed a signed copy of my COPR which was delivered on 18th(as per Canada post). No updates on my online account since then. I called CIC today and the agent confirmed they have received and processed my documents as on 29th Dec and mentioned that they have also initiated my PR card request. She was however unable to explain why my status on cic portal was not updated and when a copy of my letter would be mailed back to me.
