The ability to speak French, or any other language, usually has nothing to do with what school you go to anyway. The late Jack Layton learned French from his hockey pals and not at school. My daughter is completely fluent, despite going through the English-language school system here with never a hint of immersion. She is also fluent in several other languages that she picked up from her friends. Meanwhile, people who have known her for years, including her husband, cannot pronounce her Welsh name properly.
On a recent visit back to 'the Old Country', one of my cousins told me 'you do have an interesting accent - half Welsh, half Canadian'. That is what happens when you have been away for a long time, you do not really belong anywhere, except in your family, et dans les recoins de l'imaginaire.
