My friend got RQ- ottawa office and it took him 4 yrs to get his citizenship. he has been in Canada for more than 10 yrs with full-time job- has property in canada, kids in school. He provided all supporting documents when he applied but still got RQ. he is from US originally. It was more common in prior years of getting RQ.
I know someone else who was from an Asian country with many travels to home country- wife does not ve much proof of residency in canada as never worked in canada. well ,nothing was asked from them- took them 5 mths for the whole process- scarborough office.
I am pretty sure both were honest in their application. So, i guess it depends on the officer who is charge of your file to decide whether ur case needs more investigation. could be just random- just like auditing of tax returns.
I am pretty sure it will be ok Om. But for sure, if i was in ur place, i would have been a bit disappointed knowing that i provided all information needed and may be more (even though the process is way faster than prior years)
