<human>:  What are the differences between the healthcare systems of Canada and the United States?
<bot>: The primary difference between the healthcare systems of Canada and the United States is that Canada has a single-payer, publicly funded healthcare system, while the United States has a multi-payer, largely private health insurance system. In Canada, health services are funded through taxes and administered by the government, while in the United States, private insurance companies provide coverage and individuals are required to purchase an individual health plan or employer-sponsored plan. Additionally, in the United States, many medical services are not covered under insurance, while in Canada, almost all medical services are covered. Furthermore, the United States has higher healthcare costs than Canada due to a variety of factors, including higher administrative costs and higher drug costs.
