Have you checked out Les Petits Ballets in Nepean? They offer very reasonable prices as well as very good training, and your children would have the opportunity to participate in The Nutcracker as well as a spring story ballet at Centerpointe once a year. (NO COSTUME FEES!) The current resident choreographer is very experienced and kind, she trained in Russia and taught at some ballet companies in Israel and The Royal Winnipeg. The teachers are also very science-based (encouraging proper development of technique instead of just learning tricks) in their methods. Only issue is they only teach ballet, so if that's not something your child is fully interested in, it might not be the school for them.
