Losing your permanent resident status
You don’t lose your permanent resident status when your PR card expires. You can only lose your status if you go through an official process.
You can lose your permanent resident status if:
an adjudicator determines you are no longer a permanent resident after an inquiry or PRTD appeal;
you voluntarily renounce your permanent resident status;
a removal order is made against you and comes into force; or
you become a Canadian citizen.
Even if you don't meet the residency obligation, you are still a PR until an official decision is made on your status.
You may not be able to enter Canada until your permanent resident status is resolved either by receiving a permanent resident travel document or by voluntarily giving up your permanent resident status.

请注意这小段的标题：Voluntarily giving up (renouncing) permanent resident status。意思是说你如果想自愿放弃永久居民的情况。
