Absolutely.
You know better than anyone, Mr. Samson, that students from a francophone environment going to English-language day cares causes a real problem. It hinders the development of French in the other students in the class, and it drags them down. The more students who do not speak French when they arrive at kindergarten, the more it pulls the class down and the more it prevents others from making progress.
This can indeed be a disadvantage. It is absolutely important to work from age zero, from birth, if not before, to make parents aware of the importance of speaking French at home, especially for exogamous couples.
