Hi,
As of Nov 27,2012 the newer candidates would be issued Confirmation of Permanent Residence(COPR) from Ottawa. So my guess is from early 2013 CPP-O is going to issue COPRs as well. Future PR applicants will be instructed to send their PPs to CPP-O and not to other VOs in US to get COPR. Please read the bulletin.
Up till now we haven't seen anyone who have received PPR to send their documents to CPP-O for COPR.
If your file has been transferred to Detroit then CPP-O will instruct you to send your PP to Detroit in ur PPR.
There are 2 ways to get ur (COPR) from Detroit either mail them or go to Detroit personally if u have
US visit VISA. If you decide to go to Detroit make sure that you go on the right day because as far as
I know Detroit only work 2 days. This is a same day service so you would be issued COPR immediately from Detroit.
When you re-enter Canada you will show your COPR to the border services and you will land as a PR.
Check CIC for more information for timings of Detroit.
If you choose the mailing option. Then it will take anywhere between 3 - 8 weeks to receive your PP with COPR
stamped. Then you can go to the border and land as a PR.
I hope this information helps.
Ciao!!!
