Thanks! I suppose you can always make the request by phone or webform, but dunno if you'll actually get your wish granted.
Also, "whole family and friends" may not be possible. In the invitation for the in person ceremony in Montreal, the invitation specified that there could be "one guest per candidate". Candidate here is a new citizen. They're not exactly enforcing it at the entrance, especially for spouses and kids of applicants, but the seating is absolutely limited, and guests may be refused entry if the room is full already. I waited outside for a bit myself before the security lady checked the empty seats and let me in...
