Thanks for the explanation. Passport was courier-ed to VFS.Congratulations ! You file is fast because you have already declared them as ,non accompanying dependants and not because you just came to Canada .
Sponsor approval takes only few days after AOR in every case except very complicated cases.
Linking application to cgkey and checking ecas is good because sometimes you can miss those emails, I have seen people missing medical emails because of that but if you are linked to cgkey the mails will be there.
Also at the very last stage of the application, once you drop your passport with VFS , VFS might not inform you that the passport is ready for pick up but once your counter foil is issued in your cgkey, you can give it few days and go pick it up at VFS . It will.be at VFS already.
Have you submitted your passport to VFS already?
