This is a really old thread but has anyone been in the same situation and applied for a PRTD and just recently become a permanent resident and has left Canada just with an ECORP. Did they ask more documents to prove RO since you just became a resident. I just got my ECORP Nov 14, I have to leave canada and go back to my home country and will be returning in 2 months to resume my residency. Im hesitant to leave and apply for this PRTD not being able to provide the documents they are requesting or they will see I just become a PR.
