Hamilton is still the fastest processing CIC in the whole of Canada and I am speaking from the point of view of experience it took me 9 months from the time I submitted to CIC-Vegreville to my oath. From the moment CIC-Vegreville transfer the case, it took just a week to schedule an exam and 2 days to take the oath after the exam. If you dont have something unexplainable in your application, the delay might be attributed to the holidays. RQ can only be triggered by unexplained absences in Canada. If you failed the test, they will inform you of the next step, either appeared before a citizenship judge or others. Keep the faith alive, CIC is working to speed up its processing time to serve you better. Dont lose hope.
