I'll start with a brief comment. I'm aware that CIHR is concerned that among the four pillars of research—basic biological studies, clinical studies, health services research, and population health—health services research is the least funded, but that's partly a function of who's doing what kind of research.
A good grant, well written, has a good chance of being funded. There is still much more emphasis put on basic biological research than there is on health services research. Health services research is complicated and messy, and it's very hard to do experimentally.
We need a great deal more of it to look at issues like the preventability of the physical and mental health toll that parents and grandparents experience when they raise children with complicated lives. Those kinds of studies are possible, but they're messy.
