You will have to look at school boards based on where you live since you can’t drive. Private or public depends on how much you can and want to pay.

Your parents seem to want to visit Canada longterm and bring you with them. This will likely create some large concerns about whether your family is attempting to move to Canada. I have concerns about whether you will get approved for a study permit.
