Did you get an option to submit documents via email?Hi SatheshDyn, did you solve the problem through Web Form ? I have the same issue, I received a letter requesting to upload new documents through MyCIC account, but when I click the "View submitted application" button I do not see any option to upload them.
I got the letter 2 days ago.
"If the document requested is a copy, you may scan the document and attach it in a message to our e-mail address below. You must include your application number in the subject line of the e- mail. If you prefer not to use e-mail, you may submit copies to the visa application centre in person or via courier if you originally submitted your application there. We strongly suggest correspondence via e-mail wherever possible to avoid delays in your application processing"
