No. OHIP no longer covers the cost of hearing tests. In July of 2001, hearing tests were delisted from OHIP meaning they are no longer covered. The Ontario government's statement on why it was delisted explained: “Hearing aid evaluation and re-evaluation will no longer be insured by OHIP as these services are in the discipline of audiology and do not require a physician to provide or supervise the service.”
There are some exceptions to this rule. For instance, if you are being seen by an otolaryngologist or ear, nose, and throat specialist (ENT). If those specialists perform a hearing test during an appointment, they bill OHIP for it instead of the client. You also won’t be billed if the hearing test is ordered/requested by a physician.
The cost of your hearing test may be covered by private insurance. You can call your insurance provider to find out.
