As on date it still says that once application is submitted we cannot send additional documents unless asked by the VO. However, Im a bit scared bec Ive been seeing several cases that some applications are outright refused due to some docs that were not submitted. I was thinking that VO would ask for it before refusing right away.O_Canada said:I remember sending additional documents once Visa officer asks for it through MyCIC online application. But I am not sure if the system will allow you to send additional documents online If you have already submitted your online application through MyCIC portal. Anyhow try attaching the document and see if it allows. I do not see any harm in sending that additional information. I used this online application last year in Jan 2013, it has been more than 1 year so CIC might have updated the application to send additional documents after submitting online application .
What I am thinking is to send by email because in myCIC account it is not possible.
