for all those anxiously waiting like me, here is some positive news.
I called CIC just now and after 20mins later, a nice gentlemen picked the phone. I told him I have been waiting for 6 months now and eagerly to know anything new about my application. He checked my file and said actually all the checks have been finished, and only wait for Ottawa to sent out PPR. However, he mentioned as this is the busiest time of the year for CIC, he is not sure when the PPR going to be sent out. So, finger cross and hope everything coming soon.
