Health care in Canada is funded and delivered through a publicly funded health care system, with most services provided by private entities. While the Canadian government calls it a "public system, it is not "socialized medicine".Health care spending in Canada is projected to reach $160 billion, or 10.6% of GDP, (2007). This is slightly above the average for OECD countries. In Canada, the various levels of government pay for about 70% of Canadians' health care costs, which is slightly below the OECD average. Under the terms of the Canada Health Act, the publicly-funded insurance plans are required to pay for medically necessary care, but only if it is delivered in hospitals or by physicians. There is considerable variation across the provinces/territories as to the extent to which such costs as outpatient prescription drugs, physical therapy, long-term care, home care, dental care and even ambulance services are covered.Considerable attention has been focused on two issues: wait times and health human resources. There is also debate about the appropriate 'public-private mix' for both financing and delivering services.
