You should go delete your other two duplicate threads - they will annoy people.
The reason you're not getting the answer you're looking for is because you didn't give us enough information. How long did it take you to get to AIP? Is your application still at CPC-Vegreville, or did it get transferred to a local office for special handling? You only mention that it's been in process for a year and that you have AIP, but you don't say how long ago you got AIP. so it makes it really hard for us to figure out what might be happening with it.
If you got AIP within the normal timeline of 6-7 months and your application is still at CPC-Vegreville, you can expect the second stage of assessment to take approximately 6-12 more months after AIP. But Vegreville only handles "straight-forward" cases - if there was any problem with your application and it was transferred to your local CIC office, and they issued AIP, it's anybody's guess how much longer you'll wait for finalization. If that's your situation, your sponsor should contact the Call Centre and ask about the individual processing timeline for the local CIC office that is handling your case.
