Thank you.
I would just like to have something clarified.
I am the perfect example. My spouse is anglophone, specifically, an anglophone Montrealer. We live in La Pocatière, in a largely French-speaking riding. Our children are bilingual because we spoke English at home. They didn't, however, do their schooling in English.
My son lives in the Montreal area, west of the island, in Rigaud. In theory, his children are rights holders, and, according to what you said, if I don't apply to the Quebec government for a certificate, future generations of our family will not be considered rights holders.
