Like i said if PA is from India regardless of Outland or Inland, it is either processed in Delhi or Ottawa.
Prior to covid, it was
somewhat clear that overall, files were being completed more quickly in Canada (Mississauga then) for some countries compared to visa offices (Delhi being pretty obvious). Also it was not directly linked to whether applicant was inland or outland.
The consensus
opinion was that it was more that 'easier' (simpler) files were more often being kept in Canada for processing. I.e. that it was not so much 'lucky' to have your file retained in Canada, but that your file was actually easier for them to process and hence went quicker.
It's not clear whether that was true or impression; to some degree the opinion
looked to be plausible because (to the extent outsiders could tell, but from gcms and some info shared about files) the ones retained for processing in Canada were more simple.
This may have been wrong, but if this trend is starting to resurface but with Ottawa, more or less same conclusions: not all files sent out take longer, and not all ones retained in Canada are faster, and it most likely wasn't a random (luck) process that sent some to be processed faster but that the files were actually different.
Note, of course: it also makes no difference whether the applicant is in or outside Canada as to how the PPR is treated - any visa office can print the visa and that's driven by whether the applicant needs a visa to enter Canada.
