warm climates) and other Canadians who are out their home province or territory for a total of more than 183 days in twelve months lose all coverage, which is reinstated after a three-month waiting period. Students attending a university or college outside their home province are generally covered by the health insurance program of their home province, however, "Typically this coverage (while out-of-province but within Canada) is for physician and hospital services only." The Ontario Ministry of Health and Long Term Care, for example, states, "Therefore, when travelling outside of Ontario but within Canada, the ministry recommends that you obtain private supplementary health insurance for non-physician/non-hospital services." Such services might include prescription drugs, or ground and air ambulance services that might be covered in one's home province. Comparison to selected other countries The Canadian health care system is often compared to the U.S. system. According to a report by the New York-based independent health-care advocacy group, The Commonwealth Fund, that compared 11 rich countries, over 25% of Canadians report a body-mass index of 30 or higher—a measure of obesity—compared to 40% in the U.S. This is twice the rate reported in Norway, Sweden, and Switzerland. Canada ranked 4th in the eleven countries for the number of suicides per 100,000 compared, with a rate of 11.8 per 100,000 compared to the U.S. rate of 13.9 which was the highest of the eleven wealthy countries. In both Canada and the United States there has been an increase in "deaths of despair" which includes substance abuse and overdoses. From 2000 to 2015, the number of preventable deaths caused by treatable health conditions—diabetes, high blood pressure or some cancers—dropped from 109 to 72 deaths per 100,000. In 2016, of the eleven countries, the U.S. "had the highest rate of avoidable deaths at 112 per 100,000". Healthcare spending compared to other countries In 2018, The OECD average represented 8.8% of GDP or CAN$5,175 per person with 27% private and 73% public. Canada's health spending represented 10.7% of GDP or $6,448 per person with 30% private and 70% public. The U.S. spending represented 16.9% of GDP or $13,722 per person with 51% private and 49% public. In 2019, Canada's per-capita spending on health expenditures ranked 11th among health-care systems in the OECD. In comparison, in 2006, Canada spent approximately 10.0% of GDP on healthcare in 2006. The average of OECD countries at that time was 8.9%.
