I'll make a start and you can then join in with further details.
Some key numbers clearly show that access to research funding is inequitable certain institutions—the small and medium-sized universities—and for faculty. It's absolutely clear. Language, although not the only factor, contributes significantly to the unequal allocation of funding for research at small and medium-sized universities, and for francophone researchers. A researcher who wants to do research in French at an anglophone or bilingual institution, doesn't have access to the same services in support of their research applications and ends up abandoning the idea of submitting an application. That means that the university in question is depriving itself of some of the funding available for research in French. Many francophone researchers work at small institutions where there are fewer professors and hence smaller budgets, and where less funding is available from the granting agencies. To obtain funding—and I'm not joking here—the more money a university already has to fund research, the more it will receive. The less it has, the less likely it is to receive more.
This scenario is particularly true in the francophone research community, especially at small and medium-sized institutions. That's what Ms. Céline Poncelin de Raucourt said in the brief to the Université du Québec network, and she probably explained it better than I did on the basis of the numbers you referred to.
