as far as I remember it happened to another applicant a month ago, and apparently Vegreville sent it to Mississauga once they realised that it was the wrong category. So there is probably not much for you to do, apart from waiting for news. The other applicant received a letter explaining that her file had been sent to Mississauga and that nothing needed to be done at that stage, so I suppose it will be the same for you.
Since it has been since May, maybe you can try contacting Vegreville to explain? and see where your file is... I don't know how their system works, if they enter information in the system when the file arrives... they might be able to locate it and explain to you where it is... I think it is worth contacting them since it's been more than a month.
Sweden, thank you for your reply. I can not phone Vegreville. Call center told me will take an year for Vegreville office to get to my file. This is my concern.
