I am a PR since 2005 Aug. I have 570 days so far in Canada. I left Canada in June 2007 to do my residency training in the US. Now I am done with my training in 2010 June and plan to return. My PR expires in Sep 2010. 2 questions:
1. After entering Canada, when can I apply for PR renewal- after I complete my obligation of 730 days?
2. If PR expires while trying to make up the 730 days,
Is it legal to stay in the country with an expired PR?
That is easy... just return and stay up until you have 730 days. Then you can renew. You can stay with an expired PR but you should make sure you are in the country when it is expired. As soon as you have 730 days, you can then renew. The 730 days has to be within the past 5 years from the date you apply.
