I am confused now because in your info, it says that you only filed your PR application in 2009 and you had an interview in 2010. How could you then have a PR card which expired in 2012 and another thing, if your PR card was not expiring until 2012, why did you apply to renew it a year earlier?
If you feel that your application is taking too long, you can look up your member of parliament and see if he or she is ready to help push your case for you.
Updated my profile Info...I applied one year earlier for PR renewal because I suspected they would take some time to review residency obligations & I did not want to be tied up in Canada unable to travel (I must have a crystal ball huh?!

)
How do I go about contacting my MP? - Where do I find who to contact & address?
Thanks for the idea
