To be 100% honest, I think you have higher chances of finding someone with a similar case as yours in one of the subforums here dedicated towards Express Entry. People in this forum are either Canadian citizens sponsoring their spouses (meaning, they have never landed as PR in the first place) or PRs that have already landed and thus going through the process of sponsoring through the Family Class Sponsorship route.
Hopefully you do find some help around here though!
Hey thanks for the reply. Actually I haven't yet landed in Canada yet. Since my family composition changed I had to return my copr. Still waiting for ppr though. I have just received the medical surveillance letter
