Health regions, also called health authorities, are a governance model used by Canada's provincial and territorial governments to administer and deliver public health care to all Canadian residents.
Health care is designated a provincial responsibility under the separation of powers in Canada's federal system. Most health regions or health authorities are organized along geographic boundaries, however, some are organized along operational lines.
