Medicare is an unofficial designation used to refer to the publicly funded single-payer healthcare system of Canada. Canada's health care system consists of 13 provincial and territorial health insurance plans, which provide universal healthcare coverage to Canadian citizens, permanent residents, and depending on the province or territory, certain temporary residents. The systems are individually administered on a provincial or territorial basis, within guidelines set by the federal government. The formal terminology for the insurance system is provided by the Canada Health Act and the health insurance legislation of the individual provinces and territories.

Healthcare in Canada is delivered through the provincial and territorial systems of publicly funded health care, informally called Medicare. It is guided by the provisions of the Canada Health Act of 1984, and is universal. The 2002 Royal Commission, known as the Romanow Report, revealed that Canadians consider universal access to publicly funded health services as a "fundamental value that ensures national health care insurance for everyone wherever they live in the country."
