Health Status, Health Care and Inequality: Canada vs. the U.S.:

We find a somewhat higher incidence of chronic health conditions in the U.S. than in Canada but somewhat greater U.S. access to treatment for these conditions. Moreover, a significantly higher percentage of U.S. women and men are screened for major forms of cancer. Although health status, measured in various ways is similar in both countries, mortality/incidence ratios for various cancers tend to be higher in Canada.

Indeed, the health-income gradient is slightly steeper in Canada than it is in the U.S.

Also, The Income Gradient in Children's Health: A Comment on Currie, Shields and Wheatley Price:

...we find that the effects of chronic conditions on health status are larger in the English sample than in the American sample, and that income plays a larger role in buffering children's health from the effects of chronic conditions in England. We find no evidence that the British National Health Service, with its focus on free services and equal access, prevents the association between health and income from becoming more pronounced as children grow older.
