Can I renew my PR after 5 years?
Short answer: You renew the card, not the status. PR status does not come with a five-year expiry date. The plastic card does. IRCC's help answer When should I apply for a permanent resident card? says apply if the card expires in less than nine months, if you will return to Canada on a commercial carrier, if you need proof of status, if the card was lost, stolen or destroyed, or if you changed your name. Who can apply requires PR status, physical presence in Canada, and that you have not lost status through a removal order, citizenship, or a failed residency test.
Residency is a separate test: at least 730 days in Canada in the last five years, which do not have to be continuous. IRCC explains that on Understand PR status. Meeting 730 days is about keeping status. It is not a reason IRCC mails a new card by itself.
How many days does it take to renew a PR card?
Short answer: IRCC does not print a fixed day-count on the renew page. Use the check current processing times tool and choose permanent resident cards, then renewing or replacing. The widget is updated weekly. The number is how long most complete files took recently, not a promise for your file. Incomplete files are delayed or returned. Urgent processing, when you qualify, still has a minimum of 3 weeks, and IRCC says it cannot guarantee the card on time.
After a decision, IRCC usually mails the card to a Canadian address. Check what happens after you apply and application status. If you are moving within 3 weeks, update your address.
Do not send a second application because the first one feels slow. IRCC says the longer you have been waiting, the closer you are to the front of the line.
Does PR renew automatically?
Short answer: No. The card does not renew itself. New immigrants usually get the first card by mail after they give IRCC a Canadian address and photo within 180 days of becoming a permanent resident. After that, you file IMM 5444 when the card is close to expiry or when you need a replacement. IRCC will not notice the expiry date and ship a new card. If you do nothing, you still have status, but you may not be able to board a commercial flight back to Canada.
Destroy the old card by cutting it in half after the new one arrives, as IRCC describes on the status page.
