Arizona, sued the Ontario government for failing to reimburse her $95,000 in medical expenses. Holmes had characterized her condition as an emergency, said she was losing her sight and portrayed her condition as a life-threatening brain cancer. In July 2009 Holmes agreed to appear in television ads broadcast in the United States warning Americans of the dangers of adopting a Canadian-style health care system. The ads she appeared in triggered debates on both sides of the border. After her ad appeared critics pointed out discrepancies in her story, including that Rathke's cleft cyst, the condition she was treated for, was not a form of cancer, and was not life-threatening. Price of health care and administration overheads Healthcare is one of the most expensive items of both nations' budgets. In the United States, the various levels of government spend more per capita than levels of government do in Canada. In 2004, Canada government-spending was $2,120 (in US dollars) per person, while the United States government-spending was $2,724. Administrative costs are also higher in the United States than in Canada. A 1999 report found that after exclusions, administration accounted for 31.0% of healthcare expenditures in the United States, as compared with 16.7% 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 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 system. However, U.S. government spending covers less than half of all healthcare costs. Private spending 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. In 2006, healthcare consumed 15.3% of U.S. annual GDP. In Canada, 10% of GDP was spent on healthcare. This difference is a relatively recent development. In 1971 the nations were much closer, with Canada spending 7.1% of GDP while the U.S. spent 7.6%. Some who advocate against greater government involvement in healthcare have asserted that the difference in costs between the two nations
