@armoured Thank you for telling! Should the file move from Ottawa again if we got DM? Or is Ottawa from where PPR will be sent?
I'm not clear what question you're asking. It doesn't much matter which office sends the passport request, they'll provide options to submit the passport in the country of residence of the applicant and/or in Canada if the applicant is there.
But they don't need to move the physical file to another office to issue the visa/copr.
Note in some places like EU they may only issue at some 'dedicated' visa offices like London or Paris or Warsaw. But those are details that don't much concern the applicant (except for hassle of how to submit by courier and physical return).
(I'm not sure exactly how they handle if the applicant happens to be in a third country - in principle the visa/copr can be issued in almost any visa office, but may not be easy)
