We got AOR and we haven't sent CIT 0177 at all.
This was very confusing for us as well as in case you reply that you lived outside Canada for certain period(like we have lived), application itself is asking you to provide CIT 0177. Since we did lived in our home country for x amount of time, if we would follow the application to the letter, we would supposed to send CIT0177.
Since I couldn't understand why would I send it as it is not applicable to us at all, I just chosen not to send it at all and even worse I selected that we haven't lived anywhere else, although it is clear by looking at the other documents that we did.
My understanding is that most appropriate way would be to select yes and to send a form, where on the form you should indicate not applicable as some did. However, I trust that even goverment officers are aware of this confusing question and that you need to provide CIT0177 only if you arre trying to claim additional days, and that in case you don't every other option is fine (sending it or not).
I hope this helps you and that it makes sense.
This is all just my personal opinion, not claim by all means.
Thank you for explaining this . I did not send the form as well . Even though I was thinking to mark the box as yes and send the CIT0177 form marking as not applicable since I am not Justifying any absence outside Canada during my eligibility .However, some of my friends did this. This is the most confusing question in the form . They should change the question .
