First of all, I would say that, yes, the roadmap has been very beneficial. We have benefited in many ways.
In response to the second part of your question, as to why bilingualism is declining, there are several scenarios that could explain that phenomenon. However, I do not necessarily want to venture into that area. I am not an expert on language retention, although I may have some expertise on language retention by minority members learning English. English and bilingualism in our French-language schools are not declining, on the contrary.
