I waited 3 months after completing my citizenship exam before I decided to email our MP, Omar Alghabra. By this time, my application for citizenship has already been with CIC for 2 years and I thought I don't want to wait any longer! The MPs office emailed me back to say that they will have someone take a look at our application. Then within a week, I got an email from CIC that my Oath has been scheduled!
I think its unfair to have our applications just sitting around and all it needs is someone to take a look at it. Those applications that are older and buried should go to the top of the queue!
