I have heard in that case a person is reported to CIC and is allowed to enter for 30 days to appeal. And if you have H&C grounds of medical and you have evidence then you can win the appeal. Otherwise, you can lose your PR. However, if you are fortunate and are not formally reported then you are good and live for 2 years before renewing your PR card. Sometimes, CBSA officers give lecture for not living in Canada or meeting Residency Obligation, but do not report you formally. In that case, you are good.... Usually they prepare some documents or make you sign something in order to report you to CIC..... But I am not sure how that works exactly.. paper work and all....sakamath said:Even though this is off-topic, I thought it better to clear the misconception. A valid PR card does not mean a person has maintained his/her PR status. At the point of entry, the person has to prove that they can complete the mandatory 2 year in-Canada stay in the balance time left on the PR card. For example, if a person became PR on Jan 1st and left the country on March (say 3 months), the PR card will be valid for 5 years. But if that person stays out for 4 years, then that person simply would not be able to complete the mandatory 2 year requirement. It is at this point the person can be refused entry into Canada as (s)he would have deemed to have lost PR status.
