The Ontario Health Insurance Plan (OHIP) insures diagnostic hearing tests ordered and performed by qualified physicians. Some audiologists in private practice do not charge fees for hearing tests ordered by a physician. The Ontario Ministry of Health and Long-Term Care's Assistive Devices Program (ADP) may contribute to the cost of your hearing aid or other device if you are eligible. Veterans may be covered for both tests and devices through Veterans Affairs Canada. Similarly, Workplace Safety Insurance Board (WSIB) or other insurance plans may contribute to costs.
