Health care in Canada is delivered through a publicly-funded health care system, which is mostly free at the point of use and has most services provided by private entities. Government assures the quality of care through federal standards. The government does not participate in day-to-day care or collect any information about an individual's health, which remains confidential between a person and his or her physician. Canada's provincially based Medicare systems are cost-effective partly because of their administrative simplicity.
In each province each doctor handles the insurance claim against the provincial insurer. There is no need for the person who accesses health care to be involved in billing and reclaim. Private insurance is only a minimal part of the overall health care system. A health card is issued by the Provincial Ministry of Health to each individual who enrolls for the program and everyone receives the same level of care. There is no need for a variety of plans because virtually all essential basic care is covered, including maternity and infertility problems. Depending on the province, dental and vision care may not be covered but are often insured by employers through private companies
