I applied Dec 2019 and was transferred to Etobicoke Dec2020 and Etobicoke asked for the additional info last week Wednesday submitted it on the weekend .
Last Wednesday I heard from immigration and they gave me 72 hours to submit ; credit report for both my husband and I, joint bank account, rental lease with both name, utility bill, credit card statement etc.
The people that are writing the letters for you have to go to a notary public or lawyer to sign the letters for them . There is a feee for the process.
You should remove your lawyer as your representative and submit all the documents they had asked you before again by yourself and ask friends and relatives to write you letters and have the letters notarized . Make sure that you explain everything that you are submitting to them. Wish you luck.
