Jason Shafrin, the Healthcare Economist, has a good review of the O’Neil and O’Neil NBER working paper, Health Status, Health Care and Inequality: Canada vs. the U.S. (This paper was also mentioned by Tyler recently).

that this is mainly due to the fact that the U.S. has a higher incidence of
disease. It turns out that Americans may have slightly higher access to
treatment than Canadians.
