There's nothing sad about this situation. This person didn't follow the instructions and that's why they ran into problems.It’s so sad to hear that returning back after long waiting and getting PR.
Now what you did to save PR? Bcoz my condition is also similar as u have and I also need help. Plz help me
You must add your spouse to your application before landing. This includes returning your COPR and waiting for 3-4 months for IRCC to process the paperwork for your spouse before getting a new COPR. If you don't do this, then you must apply for PR again from scratch.
