Let me give some insights on this. The office mentioned in our BVL normally is the office where our biometrics are received and processed. Most of the time it ahould be either our primary or secondary office. So usually BVM's of sds and non-sds are normally issued and processed under Ottawa office. Even the applications who's decision came way before had their BVL issued from Ottawa from what I see.
So what I am trying to say is that the office mentioned in our BVL can or cannot be our primary office. As for SDS from india it might be ottawa is it most of the time and for Non-SDS, Delhi is the one. Some times due to work load our applications maybe transferred but it is not that common. So you folks receiving BVL from Ottawa might not mean that it is being processed in the mentioned office. Someone in this forum confirmed this by contacting IRCC before. We only will know our office by calling them or getting our gcms notes. Thanks for reading
