More taxes are spent on health care in the USA than in Canada.
Health care is one of the most expensive items of both nations� budgets. In the United States, the various levels of government spend more per capita on health care than levels of government do in Canada. In 2004, Canada government-spending was $2,120 (in US dollars) per person on health care, while the United States government-spending $2,724.[68]

A 1999 report found that after exclusions, administration accounted for 31.0% of health care expenditures in the United States, as compared with 16.7% of health care expenditures in Canada. In looking at the insurance element, in Canada, the provincial single-payer insurance system operated with overheads of 1.3%, comparing favourably with private insurance overheads (13.2%), U.S. private insurance overheads (11.7%) and U.S. Medicare and Medicaid program overheads (3.6% and 6.8% respectively). The report concluded by observing that gap between U.S. and Canadian spending on health care administration had grown to $752 per capita and that a large sum might be saved in the United States if the U.S. implemented a Canadian-style health care system.[69]

However, U.S. government spending covers less than half of all health care costs. Private spending for health care is also far greater in the U.S. than in Canada. In Canada, an average of $917 was spent annually by individuals or private insurance companies for health care, including dental, eye care, and drugs. In the U.S., this sum is $3,372.[68] In 2006, health care consumed 15.3% of U.S. annual GDP. In Canada, only 10% of GDP was spent on health care.[5] This difference is a relatively recent development. In 1971 the nations were much closer, with Canada spending 7.1% of GDP on health while the U.S. spent 7.6%.[citation needed]

Some who advocate against greater government involvement in health care have asserted that the difference in health care costs between the two nations is partially explained by the differences in their demographics.[70] Illegal immigrants, more prevalent in the U.S. than in Canada,[citation needed] also add a burden to the health care system, as many of them do not carry health insurance and rely on emergency rooms � which are legally required to treat them under EMTALA � as a principal source of care.[71] In Colorado, for example, an estimated 80% of illegal immigrants do not have health insurance.[71]

The mixed system in the United States has become more similar to the Canadian system. In recent decades, managed care has become prevalent in the United States, with some 90% of privately insured Americans belonging to plans with some form of managed care.[72] In managed care, insurance companies control patients' health care to reduce costs, for instance by demanding a second opinion prior to some expensive treatments or by denying coverage for treatments not considered worth their cost.

Administrative costs for health care are also higher in the United States than in Canada.[7
