Good you found out. Someone who got PPR and waiting for COPR said she filled the form manually and got medical request the following day.I also need to fill this form but I really don't know what Visa office processes my application. I wrote an email to CPC-CTD-Ottawa@cic.gc.ca and currently waiting for the reply.
Kyiv Visa Office said that I can find this information in MyCIC AOR letter but there is no such information in it.
UPDATE: I found info, that it is normal to write IRCC in office name and ONLINE in office address.
of course, IRCC and ONLINE are correct.
I already submitted though.
