So I had this issue for my ADR. I think some excellent suggestions have been made. To add to them, this is what I did:I believe you can print all of them out(including the extra sheet), scan them into one pdf file and then upload. I believe you have to do print-and-scan anyway since the signature is required and it's not a file that can be electrically signed?
btw for my case, declarings of "all of the information provided above is truthful and accurate" are added blow each page of the extra sheets, with signatures and dates
A. I added a cover sheet with each upload. On the cover sheet, I indicated my application number and UCI (I had to upload documents for my spouse too, where the application number was the same but different UCI). I also indicated which part of the ADR I was responding to and provided a list of attached documents. For example, in my IMM5406 upload, I said,
(1) Completed and Signed IMM5406;
(2) Extra Continuation sheet containing: a. continuation of Section C (Brothers and Sisters – including half – and step-brothers and sisters)
b. Continuation of Sections A, B, and C – All names written in my native language
B. Then the actual IMM5406
C. Continuation sheet - in the header of the continuation sheet, I mentioned the principal applicant's full name, application number and UCI. I formatted the body of the sheet in the same style as that of the IMM5406 using tables in MS Word. Using subheadings to denote each section of the form that the information was relevant to. Finally, included a line with my name and date and signed the form.
Scanned all forms and uploaded to MyCIC.
