It's important to fund all three areas currently covered by the three research granting agencies, both in the health sciences and in the social sciences and humanities. There can be great advances and innovations in these areas.
It's also important to consider interdisciplinarity. The Bouchard report mentions this. Often, students and professors risk falling between the cracks when applying for grants or scholarships from these agencies. Interdisciplinarity is increasingly fashionable, and a project could target the humanities, but also health sciences, for example. So it's also important to consider that all these areas can go together.
