Something weird happened in my case. I have filed with the help of a consultancy and they have an Attorney in Canada who is my official representative. He died 2 weeks ago. I was shocked when I heard this.Man that sucks maybe you will get update tomorrow
I sent a web form and asked for how to proceed so, I got an email from the IRCC agent that you can appoint a new attorney or cancel the representative. He also mentioned that your file look's good and everything is in order and we do-not require any additional document from you.
Just fill the IMM5476 form and upload again in your EE profile which my consultant did.
I am praying for everyone that nothing like this should happen with anyone and we should get to positive end.
