Final answer:
The supply side of health care in Canada is dominated by the public sector, in contrast to the United States, where both public and private healthcare systems coexist.
Step-by-step explanation:
In Canada, the supply side of health care provision is dominated by the public sector. This contrasts with the healthcare system in the United States, where there is a mixture of public healthcare (government-funded) and private healthcare (privately funded). In the US, healthcare delivery and health insurance are largely maintained by private companies, and while not-for-profit organizations do play a role, a significant proportion of healthcare providers operate as for-profit entities. Conversely, Canada's healthcare system, known as Medicare, is an example of socialized medicine and is publicly funded and administered on a provincial or territorial basis, within guidelines set by the federal government.
