Same issue with us - won appeal early Feb. 2021, Decision given the same day and filed with IRCC within 2 days thereafter. We had previously been told our file was transferred to outland visa office, which was confirmed by our MP's office. Our solicitor contacted outland visa office and found that information to be incorrect, outland visa office indicated the file was still here. A further follow-up with MP's office this weeks shows that our file is actually still here in Mississauga.... 6 months after receiving approval. The only explanation given...Mississauga is experiencing backlog due to Covid.
Covid is the convenient excuse now for all delays (even though we all experienced delays before Covid).
