I did the same, it's just about this waiting time, I replied to the IRCC last Tuesday and still waiting for the eCOPR.I am of the assumption that the portal is created based on the details they ask and the doc is not required. It is the same email which they sent me the confirmation doc so I replied back to it. Did I Do something wrong?
Congratulations! and I'm hoping the same for those who are waiting for this EMAIL.
