Thanks. So surely your case was moved to NDVO before IP2 stage, maybe around IP1. Very curious about why some cases are dealt at CPC OTTAWA itself even for outland candidates while some are referred to local Visa office. Considering I'm in IP2 and all 3 stages are complete except Security, I believe this should happen at Ottawa as well, like one of my friend who had similar timiltimas mine but he got his PR a few weeks back from Ottawa( He is from Kolkata).
It could be purely based on work load distribution or they might send it across to a local VO inorder to verify employment and other eligibility criteria which is better understood by a local VO rather than CPC. Ottawa VO seems to be the one processing maximum number of PPRs. Hence if alls well, they might only take a decision and issue you a PPR. But if they feel that it needs more scrutiny, they might send it across to NDVO/Chandigarh or Bengaluru
