wow you are lucky, extremely lucky we are waiting still with Feb aorUpdate: Finally got my portal credentials after what felt like an eternity to me. I received the first email on Jan 06 and it took them 16 calendar days to get back to my email. I am not sure if this has anything to do with the lengthy follow-up email that I sent on Wednesday offering them a way to send the COPR by email so I can send the photos by mail if they are having any technical issues.
As per the portal, we should be able to download our eCOPR as soon as the self-declaration has been accepted by IRCC (I wonder how long this is going to take). A lot of users reported seeing this self-declaration only recently. Maybe this is IRCC's way of streamlining the process of at least getting eCOPR so we do not have to spend too many days being not-temporary-residents, LOL.
