Sharanki, hopefully everything will be just alright. It could be mere formality. You might have read on this or last page, one of the reader shared a friend's similar experience, who had appointment with Citizenship Judge and now got the Oath.
Carry every possible document well arranged to prove you had been living in the country. Such as the following, Rental / ownership, Utility bills, (Phone), credit card statements, T4, pay stubs and other documents from the last years.
All they want to established is that if you were traveling overseas did you still have strong ties & strong intention to live in Canada or visiting Canada now & then just to obtain Canadian Citizenship.
Out of curiosity, how soon you have see the Citizenship Judge.....days between you received the letter & appointment with the judge.
I wish you all the best & luck. Stay positive !!!
