Actually, the Université du Québec has long been concerned about the decline of French in Canada, particularly in science, where the decline is especially pronounced. You have likely seen a lot of data published about the fact that, since the 1960s, barely 8% of scholarly journals created in Canada have been in French.
In the natural sciences, engineering and health fields, there are virtually no options for publishing research findings in French. As a result 90% of publications in those fields are in English, not to mention that only 5% to 12% of applications submitted to the granting agencies are written in French. Historically, the success rate for funding applications submitted in French is lower than for applications submitted in English. I could go on at length about the inequalities.
To answer your question, even among the U15 group there are only two francophone institutions, and neither of them is part of the Université du Québec or the Alliance of Canadian Comprehensive Research Universities. Meanwhile, the Université du Québec is the largest francophone university network in Canada and shares the rest of the pie, as we said earlier, with the other institutions.
To summarize, as noted in the brief from the Association francophone pour le savoir, Canadian research conducted in French is crucial for the vitality and development of francophone minority communities. For francophone communities to thrive, they need to develop knowledge about themselves, and the most appropriate language in which to do so is French. They also have to train a highly qualified workforce in their own language. Through research, institutions connect with their communities to better serve them. When research funding is concentrated, all of that is at risk.
