The question is too broad.
Indeed, from what you were saying, or perhaps it was Calina who said this, once grade 12 is over, many students are no longer fluent in the second official language, because they have not had an opportunity to speak it. Indeed, only 20% of them go on to speak the second official language. The others lose their ability to speak French.
Do you not feel that the government also has a role to play in promoting both official languages in the country? When I talk about promotion, I'm not saying that it should do this blindly. In my opinion, we need to create positions where bilingualism is essential. We must also do some promotion in the universities. Teaching the second language should not come to a halt in grade 12, but should be continued at the university level as well.
