Hi, I got my PR in January 2015 and stayed in Canada as a pr for 5 months only. Then left Canada due to family issues. Since then I have been working and living in home country without any travel. I am 37 years old single. Since I was 17, I lived in Canada for 12 years. I want to update my status in Canada and move back to Canada for good. Do I have a chance to get my pr status back?
You hold PR status until CIC strips your status or you renounce it. Therefore, you don't need to get your PR status back. You already have it.
If you want to move back to Canada, you just have to move back. If you are in the US, all you have to do is go to a land border and ask for admission. If you are overseas, then your only option to get back is to get to US, and then go to land border/POE to get into Canada. You can't fly to Canada as PR with expired PR card.
Your admission to Canada is nearly guaranteed (as a PR), but if border officer decides to grill you about your past presence or absence, he will know you were out of Canada since 2015 and are in breach. In recent years (I just don't recall exact year) a new system was implemented, that automatically tracks departures from Canada. If they had the system in place in 2015, they won't even ask you about time you spent out, they will know it right away.
It would then be up to individual border officer what to do. They could either report you or waive you in without any trouble. If they report you, you will have 30 days to appeal. And then you have to make a case before IAD. Unless you have very compelling H&C grounds to remain in Canada, chances are IAD would rule against you (
as a matter of law), and you would be eventually deported. But if you were lucky and waived in without being reported, you would just need to stay in Canada 2 years, and you would then be able to apply for a new PR card and be in full compliance with RO, unless you left Canada and breached it again. Best of luck to you.
My personal experience with Canadian border guards on US border is that they are obnoxious, aggressive and hostile bunch. They used to consistently send me to secondary inspection when I was a NEWLY landed PR (I couldn't be in breach of RO even if I wanted to), and they grilled me about my residence as if I was an international criminal on INTERPOL's watch list. I hated the guts of those donkey holes afterwards, and wish I had the confidence and maturity back then which I have now, because I would not hesitate to create long paper trail, report them to their supervisors and even file a law suit for damages (I don't care if I would win or loose the case, I would still make a point by serving summons on agency heads and forcing them to defend themselves in a federal court, even if it meant filing Motion for summary dismissal).
