Ontario Health Insurance Plan

The Ontario Health Insurance Plan (OHIP) is the government-run health plan for the Canadian province of Ontario. OHIP is funded by taxes paid by the residents and businesses of Ontario and by transfer payments from the federal government.
Every Ontario resident with his or her primary and permanent home in Ontario is entitled to free access to emergency and preventive medical care under OHIP. Ontario residents may go to a participating doctor—essentially every doctor practising in the province—any time they wish (subject to the consent of the doctor) and the services are billed through OHIP to the government. It does not cover such areas as prescription drugs or dental care, although Ontario does have a drug insurance plan, for use as a "last resort", known as the Trillium Drug Program.
Delisted care
Until 2004, OHIP also paid for an eye examination every two years and limited chiropractic and physical therapy services. After May 2004, however, most eye exams and all chiropractic and physical therapy were "delisted", or removed from coverage, by the Liberal government of Dalton McGuinty. Provision continues to be made for free coverage to minors. Annual eye examinations are free for seniors (over 65) and those receiving ODSP (every two years)[1].
Eligibility
In order to be eligible for coverage under OHIP, a person normally must be a Canadian citizen or Permanent Resident or a holder of a work permit as set out in Ontario's Health Insurance Act, must make his or her permanent and principal home in Ontario, and must be physically present in Ontario 153 days in any 12-month period. Canadian citizens or permanent residents returning to Canada from another country are not normally covered by OHIP until they have been resident in Ontario for three months. It is recommended to obtain private health insurance to cover this three-month period. For those Canadian citizens or permanent residents moving to Ontario from another province, the province of previous residency will continue to cover them during the three month waiting period.[2]
Precursors
Ontario's first government-run health plan was known as OMSIP (Ontario Medical Services Insurance Plan), established and enacted on 1 July 1966. On 1 October 1969, it was replaced by OHSIP, the Ontario Health Services Insurance Plan, as a provincially run and federally assisted plan under the federal Medical Care Insurance Act for establishment of a national medicare plan. In 1972 the plan name was shortened to simply OHIP
