British education to Canadian education.

We are a family of four currently living and working in the South Coast of the UK. Our daughter is applying for a Toronto university and if she gets in then we as a family are considering re-locating to Toronto where we are from originally. Only issue is that our son has just stared GCSE's so we would be moving in the middle of these
Anyone have any experience of having done similar and how it would work, how he would slot back into the Ontario education system, etc etc

The usual solution is do the International Baccalaureate instead.
