Medicare (Canada)
Medicare () is an unofficial designation used to refer to the publicly funded, single-payer health care system of Canada. Canada does not have a unified national health care system; instead, the system consists of 13 provincial and territorial health insurance plans that provides universal health care coverage to Canadian citizens, permanent residents, and certain temporary residents. These systems are individually administered on a provincial or territorial basis, within guidelines set by the federal government. The formal terminology for the insurance system is provided by the "Canada Health Act" and the health insurance legislation of the individual provinces and territories.
Health systems by country
The United States is alone among developed nations in not having a universal health care system; the 2010 Patient Protection and Affordable Care Act provides a nationwide health insurance exchange that came to fruition in 2014, but this is not universal in the way similar countries mean it. Healthcare in the U.S. does, however, have significant publicly funded components. Medicare covers the elderly and disabled with a historical work record, Medicaid is available for some, but not all of the poor, and the State Children's Health Insurance Program covers children of low-income families. The Veterans Health Administration directly provides health care to U.S. military veterans through a nationwide network of government hospitals; while active duty service members, retired service members and their dependents are eligible for benefits through TRICARE. Together, these tax-financed programs cover 27.8% of the population and make the government the largest health insurer in the nation. The U.S. also spends 17.9% GDP per year on healthcare, more than double the nearest developed nations expenditure.
