That's an excellent question, and I think the answer is that we're lagging behind. This is mainly because our attention is always focused downstream, once people have a disease and how we can cure them. That's the immediate necessity. The investments upstream are very difficult to come by, and you've pointed them out. It's not merely the risk factors of healthy eating and active living, but it's those social determinants of health that many of my colleagues have spoken about: poverty, lack of education, municipal infrastructure, etc.
I think one of the examples we have in Canada that is going to be an interesting experiment is the Government of B.C.'s ActNow program. They have taken out of the premier's office a whole-of-government approach, where every ministry has to account to the premier's office for what they are doing in their ministry, be it agriculture, housing, etc., to help prevent disease in the population. As I mentioned earlier, there's not only that interjurisdictional piece, but this is going to take a whole-of-government approach. And even though public health might have a public health agency, the levers for health are in many other parts of government.
