What are the most family-friendly suburbs in Toronto?

Hi!  My family is moving to Toronto from the US next month.  My husband’s office is in Waterford, so we’ve been looking at both Burlington and oakville.  After some research, I think we have decided on Oakville. We are looking at Southwest oakville, like Lakeshore Woods neighborhood.  Still exploring to find the right neighborhood.  We are trying to figure out schools for my 5 year old twins.  They will be starting kindergarten in the fall (in pre-K now).  Are there any good Private schools in the area?  We have looked at Fern Hill School, Burlington Christian Academy, and Oakville Christian school, but we don’t know which one is best.  We are only living in Canada for 3 years, so we need to make sure it’s a seamless transition when we move back to the US school system.
