Expire PR Card since 2015. What are our options

We did soft landing in April 2011 and were not able to go back to Canada to settle. I understand that the PR status doesnt expire but is there any possibility that we now live and get everything legalised.
Or surrender the PR and try the process again( only if its possible) .

What is our options.

Thank you
