or not but I hear all the time about people who have gotten into Canada without meeting the residency requirements.  If he cares much about keeping his PR, he should come to Canada ready to stay for 2 years without a break.  If he gets in, he can do that, arrange his drivers license, health card registration etc. before his PR card expires, then let it expire and stay in Canada for the 2 years until he meets the residency requirements again.  Then he can apply to renew his PR card again based on staying in Canada for 2 years in the previous 5. If he does get checked by CBSA when he arrives, they can start the process to revoke his PR and he may appeal that if he wants to but without good reasons for not meeting the residency requirements, he wouldn't have much chance of winning the appeal and will lose his PR. Because it's CBSA's job to check for residency obligations.  As Leon mentioned, they don't do it ALL the time.  There are people who slip through but I hear about the other side, those who don't slip through and are referred for admissibility hearings.  Leon's right.  They don't often win.  And I tend to err on the side of caution.  The 80/20 rule applies with most things in life.  Using that, you could say that 80% of the time CBSA will check and 20% of the time, they won't.  Since it's in their job description,
