We wrote a book about a Canadian study on graduates of French-language schools and another about English-language schools. The analysis and all the data on ethnolinguistic vitality that we included in the study point to two possible scenarios. I'm not making any predictions here.
One of the potential scenarios is, on the francophone side, that, with government assistance in particular, progress can be made on plans for institutional completeness and linguistic legitimacy. That's the government's role. However, since we don't support the base, fewer and fewer people will attend French-language institutions and use the language.
On the anglophone side, our analysis points to a scenario in which people will have no problem using English because of the considerable attraction it exerts. However, as a result of the fact that Quebec strongly defends French with its Bill 101, it could lose some of the control it exercises over its own institutions and over the legitimacy of that language in Quebec.
These two scenarios are somewhat based on the strengths of each group.
