Yes I got defamed because I got charged with a crime I didn't do and that's what pushed me to go to school outside canada, so that I can prove to them that even though they charged me and failed to make me guilty I just want them to realize that i actually am a good person
It's not about showing them that you are a good person.
You need to meet the residency obligation to keep your PR status.
If you do not meet the residency obligation, then you need to try to find a way to return to Canada without being reported at the border and then remain in Canada without leaving until you meet the residency obligation.
If your PR card has expired and you are unable to fly to the US and re-enter Canada through a US / Canada land border, then you need to try applying for a PRTD under H&C and to try to convince IRCC that you had compelling H&C reasons that kept you outside of Canada.
