>Personally, I think it would be fine if English speaking children attended French speaking schools while still in grade school. After that, I think the balance between learning the host nation's language and learning the basic educational requirements becomes blurred. I would think both levels would decline to an unacceptable level from the junior high or middle school level on up. It would probably make more sense to have host-nation language training as a required course instead in the school that does not teach in English.

I completly agree with you.

>Yet, I was not even aware that you could choose between attending a French speaking school and an English speaking school! Which is the most in demand and why?

French school is more in demand here because french is the native language for the majority of citizens of Quebec (and because it's the law...)

The choices between french and english schools is a matter of debate here. Not everyone can send their childs to english school, you have to meet certains rules (if I remember correctly, you can send your childs to english school only if you have been to english school yourself). This law doesn't apply to university however, you can chose the university of your choice.
