Canadians do not pay for medically necessary hospital and physician services. However, in addition to hospital and physician services, provinces and territories may provide some public coverage for a range of additional services and benefits to their residents. Coverage for these additional services and benefits is often restricted to certain groups (e.g., low-income residents, children, social assistance recipients and senior citizens). These benefits are outside the scope of the Canada Health Act, and as such can be provided on the terms and conditions decided by each province and territory. Thus, public coverage for these services will vary from province to province across Canada. Generally, most Canadians pay out-of-pocket, use their private insurance, or co-pay for supplementary services or any health care service not considered medically necessary.
