I received the same letter stating my application was sent to wrong location to Mississauga instead of sydney which i selected in document checklist for spouse living outside canada. I have sent an email to PMO , immigration minister , MP offices about the IRCC sent all the proof as well but they still blame me that it was my mistake i got so frustrated that i mailed out the whole with explanation letter sent to above offices. I sent webform multiple times but seems like they don't care. It is somebody who is incompetent. we should all raise a petition so that they can react fast. Contact me at 7805990417.
