Hi there.
I think I can provide you all with some tips on the bigger picture concerning RQs. (Just to clear that out - I have received mine 3 months ago.)
First of all, you have to understand one major thing. You see, in good times (prior to 2008-2009) the whole process was much easier for the only reason - the whole world (Canada included) was thriving on the last bubble capitalism has presented us with - namely the housing bubble. Nobody minded even some fraud here and there to obtain Canadian citizenship. Why bother if economy is good and everyone is needed in the world of perpetual growth.
Make no mistake here, powers that be know exactly what is coming and it's no good, trust me. I don't want to be off topic here so I'll just cut it short - the bubble here is about to pop big time. It can't be avoided and you can't even imagine how much does Canadian economy depends upon housing. At least twice as much as US, not to mention that Canada depends economically upon US big time.
Now back to the topic.
On one hand, Canada has some obligations towards those millions of immigrants who has already entered the country. Health care for instance. But they know damn well, that within 2 -5 years they would be unable to keep up to all those obligations and there is huge potential even for civil unrest here.
On the other hand, according to law all us landed immigrants are good to become citizens if we do not commit any crime and stay here long enough. Period. End of story. Even if you were not working here for a single day it doesn't affect your right to become a citizen.
So given the upcoming "sh1t hits the fan" event they are eager to kick as much of us from the country as they can. They can't do it right away legally but they are desperate to. Solution? - if you are in this thread you know it already. They delay process as much as they can. Ever wondered why don't they have concrete deadlines for reviewing RQs? Here is your answer - they pray that you'll say "screw it!" and leave. That is the only legal remedy they have. Another side effect is that people on the hook are unlikely to make much noise (if any) in case of any further hardship. Catch my drift? We were needed here 5-6 years ago but not any longer.
Now let's be more specific as to what should you do, or rather what you should not.
1) Do not bother them with calls or anything. This f@cked up system is based on the assumption that if you have settled yourself here you wouldn't be very nervous about your citizenship. It is an easy concept to understand: if you work here, have your income, your family, your home why exactly you are not satisfied with PR status? Voting? Give me a break! You can spend at least 7 months a year elsewhere. What more? On the other hand it you are nervous - this feeds their hopes that you might leave saying "screw it" (exactly what they want from you) so you are the sweet client (if you know what I mean) and a little push (say 1 year more of waiting) might easily kick you out. Remember they use your emotions against you.
2) Do not bother yourself with much of a paperwork preparing your RQ. Don't get me wrong here - please collect enough to prove each and every week and date you claim you lived here. But let us see an example: you have your passports, your lease agreements for the whole period and your bank statements and nothing else. That is more than enough. Why bother collecting OHIP history for instance if you never visited a doctor? We are mostly young here, you know... What "other tires" does the law require to have? Going to church - what if you are an atheist. Or (more likely) you believe in God but you never ever wish to show it off? And so on and so forth... Just provide enough solid evidence that you live here for the period in question and relax.
Bottom line, if they had any legal reason to refuse your application you would know it soon enough. The only reason your oath ceremony is postponed - they do NOT have any reason to refuse you. Their only hope is that you refuse it yourself which would further prove that you never intended to live here in the first place. If you are serious about living here - you have your PR which is more than enough fro everything.
So stay cool, prepare for the worst and remember they would LOVE us all to say "screw it and leave". I do not plan to do them that favor. I'm cool as is.
