Why not fill out the CSE form on the CIC website to find out the visa office? That's how I found out - they replied to me in about 4 working days.
I've also travelled a lot in the past 10 years - and changed jobs a few times as well - so wondering if that's the cause of the delay/non-movement
Was the visa refusal within the past 10 years? If not then I don't think it would matter.
I am sure, hopefully, that the processing times have just slowed down in the past couple months because of the larger express entry draw sizes (sux for us but what to do
) - and especially this wait seems long because the PNP was faster than we had expected and we got spoilt
I think the fact that you did not receive any ADR until now is a good sign, and hopefully we will all get some sort of indication regarding our applications soon!
