That is per capita. Sum up all health care expenditures, divide by population. $11,126 per person/year for the year surveyed.
All trans-national comparisons are subject to a lot of a caveats, and in some dimensions there is no possible meaningful comparison (rates of urban gun violence US vs. Japan or Switzerland, for example.) In the US, think of the cost of ballistic wound and injury care in Chicago, for example. There is no hyper violent minority population shooting each other in Canada. Or Switzerland, or Japan. The emergency care costs that are the result of urban gunfire are not trivial, but there is no comparable component to Canadian health care expenditures. So, by the time you get done footnoting these transnational comparisons, they are basically worthless.
Well, there are the Jamaicans in Toronto, and the Chinese and Indians (dot, not feather) in Vancouver getting a bit frisky lately.
