I am about to send in my sponsorship application to be approved to sponser my wife from new Delhi. We have a complete application as well as her completed medical exam. Assuming all is in order, how many months from this time the office receives her application can she come to Canada? I've tried searching this thread, but there are too many pages

I read on the processing times site it will take up to 14-16 months, but I also discovered this form:

So now I am confused! Is it seriously not going to take 16 months? Can someone help with a fair approximate date?
