I have the same problem here.
I am really thinking to switch my application to outside Canada, maybe London. It's only taking few months for cases to be finalized.
I applied in December 2008 and I been waiting. I got my AIP back in June 2008 and no more updates.
It's so frustrating. Applying from outside Canada is way better and faster than applying from inside, plus you can always come visit during the application process.
My concern is that, what should I tell them for the reason of switching my application to outside Canada, and the other issue is that I have to prove that I will come to live back in Canada after I get my PR.
It is confusing!!
