I think you need to clarify what it is you want for your child's education. What things count to you as a family:
onsite facilities and grounds?
range of extra curricular activities?
camps/travel opportunities?
subjects offered/curriculum style?
learning support/ flexibility of learning?
type of people who will be going to the school?
languages taught/immersion programs?
academic outcomes?
class size/school size?
disciplinary approach?

These are going to be different between schools (and I'm not suggesting that private is always better than public).
