Look what I found on Twitter >>
2018 post by someone "Sent PGP2018 app via Reg. mail to CPC-MPGP,Ottawa & Signatory on Tracking shows SCI SCHUITEBOER. Is this correct name/office of IRCC?"
IRCC replied "SCI SCHUITEBOER is a company that works to scan and sort applications for our processing centres. When this shows up within your tracking information, the parcel is being received by CPC-M. Thank you!"
My application was received and signed by S SCHUITEBOER. Not sure if this one is a name given to a different centre.
This has been discussed at length in the previous pages...
