That's a big question.
In 2018-19, 46% of the revenue for post-secondary institutions came from governments. The federal government's share was around 10%, and just over 25% came from tuition. Those are the main revenues for post-secondary institutions.
If we want institutions to become less dependent on tuition fees, more government investment is needed. In my view, this option is the priority. In addition, it's important to understand the following dynamic. Institutions have been able to increase tuition revenues largely because of international students, which is another issue. This issue goes well beyond official languages. However, it's more difficult to develop strategies to recruit international students. Also, the western academic units have had many financial issues in this area.
