The Ontario Health Insurance Plan (OHIP) is Ontario's publicly funded health insurance system, providing coverage for medically necessary services including physician visits, hospital care, and many diagnostic tests. Ontario residents receive OHIP cards enabling access to insured services. OHIP is funded primarily through provincial general revenues (including the Ontario Health Premium) and federal health transfers. While healthcare is provincial jurisdiction, municipalities interact with the healthcare system through emergency services, public health programs, long-term care facilities, and addressing health-related issues like homelessness and addiction. Understanding OHIP helps citizens navigate Ontario's healthcare system.
