I would say that my colleague's answer really points to an important element of the solution. There has to be a real commitment throughout the educational program. It was mentioned earlier: French thinks differently and has its own vocabulary, so people need to have access to knowledge in French, regardless of the field. That is an important starting point.
Second, we have to seat all the actors around the table and create the necessary environment. For example, the three granting research councils have to make a commitment to better fund the research being done in French at all levels. There again, this calls for a major commitment, that would support the academic community from one end of the country to the other and make it possible to create this great francophone environment where research could be done in our language, based on the authors' choices.
