I don't know whether you've considered the case of Quebec more extensively, but, in overall terms, anglophone universities in Quebec receive 30% of funding, even though mother tongue anglophones represent 8.4% of the population. According to figures from 2000 to 2017, federal funding for English-language universities rose from 34.5% of total funding to 38.4% over that period.
According to the only study I've seen that deals with this, funding for French-language university services outside Quebec—I don't mean French-language universities, since there aren't many—fall below the percentage of francophones in the population
Have you looked at that?
