I am confident that Herouxville's regulations were in French, and have been translated into English.
They could have added:
Language.
In our community, we speak French. French is the language of law and of business. Public education is conducted in our language, French. The speaking of other languages is, of course, completely legal. However, if you come to work and live in our community, you are expected to learn French, and all of your dealings with the government will all be conducted in French. Our businesses cannot be required to speak any language but French when doing business with you. Your children will be taught in French in the public schools, and the private schools are also required to educate all children in our language. You must send your children to school, and they must learn French. This is a condition of living with us, and it cannot be avoided. We speak French, and if you plan to live here, you need to learn French and to understand that your children will be educated to speak French fluently, and that it is illegal for you to resist this. We have democratically enacted these laws because we understand that it is necessary, for participation in our democracy, that every person be able to communicate with everyone else in the common tongue. In our place, that tongue is French.
