congrats first of all don't stress. it will be very straight forward most if the officers are normally nice. They will ask basic questions like where are you working? have you ever been outside Canada? so remembering dates will help. mostly they have your citizenship application right in front of them so they ask simple questions from there most importantly they will definitely and thoroughly check each n every page of your passport. and if all goes well most probably tell u about oath.. best of luck n update the forum after interview.
