Hi, I am sorry to say that I am not sure there is a 'normal' to be honest. Time frames vary by province, by the individual, numbers of applicants, how busy the offices are and so on. Some applicants background checks take longer than others, some officers are slower at processing and so on. I personally think what focuses them more is the average '12 months' to complete the whole process. Whenever I have called CIC that is the line I always get.
For example, I am a Victoria applicant and have been in process since November. Victoria has no permanent citizenship centre for interviews, tests or oaths, we have to wait until they receive enough applications to warrant them coming over from Vancouver and setting up a 'one off' temporary location for two days or so at a time. Personally, I am not expecting any test stage until May or June at least. There is no advance notice showing any plans for a temporary office being set up at the moment. Unfortunately, at the 'in process' stage we are not asked if we are willing to travel elsewhere if it would help. Sadly, it is just a matter of patience for everybody, which is far from easy I know. Wishing everyone well in their own applications - we all feel the pain and are with you on that!
I am Nanaimo applicant and it is still IP since december the 6th with the last update for FP that they recieved since Jan 18th. Other than that no updates and I don't like to call the call centre to inquire on my file unless it is super necessary.
It is really bad as I have to go to the US for exam in June and I have to defer my annual vacation trip maybe till August in hope I hear from CIC.
