Medical and vision standards: G and M class licences

In Ontario, all drivers are required to meet basic medical and vision standards to operate a motor vehicle. Find out more about medical standards and tests for non-commercial drivers.

Medical standards

If you drive a car, truck, motorcycle or other passenger vehicle in Ontario, you need to meet the medical standards set out under Ontario Regulation 340/94 (s.14).

The Ministry of Transportation assesses all drivers directly against the national medical standards provided by the Canadian Council of Motor Transport Administrators (CCMTA).

Physicians, nurse practitioners and optometrists are required to report patients who have or appear to have certain high risk medical conditions, vision conditions and/or functional impairments. In addition, physicians, nurse practitioners, optometrists and occupational therapists have the discretionary authority to report conditions that, in the opinion of the healthcare practitioner, make it dangerous for a person to drive.

Vision standards

You will need to pass a vision test when you apply for your G1 or M1 licence. Your vision will be screened with both eyes open and examined together (with or without the aid of corrective lenses). If you have vision in one eye only your vision will be screened using only your functioning eye.

The screening will check that you meet the standards set out in Ontario Regulation 340/94 (s.18).

If you don't meet the standard for peripheral vision, you can apply for a waiver.

Vision Waiver Program, Class G

If you don't meet the standard for peripheral vision (120-degree horizontal visual field), you may be considered for a vision waiver.

You may be eligible if you:

  • don't have more than 6 demerit points on your driving record
  • haven't had your licence suspended within the last 5 years because of a Criminal Code conviction for an offence committed by means of a motor vehicle
  • haven't had your licence suspended within the last 5 years because of certain Highway Traffic Act convictions
  • haven't been involved in a collision with an associated conviction under the Highway Traffic Act for certain offences, within the last 5 years and within the time of your vision loss
  • meet all other qualifications for your licence class
  • don't have a medical or visual condition or disability that may significantly impair your driving ability, either alone or combined with a reduced visual field

You will need to provide:

  • a satisfactory medical report
  • a satisfactory vision assessment from an optometrist or ophthalmologist
  • a satisfactory functional assessment from an approved assessment centre for Class G Vision Waivers. This assessment consists of several standardized tests, both in the clinic and on the road

For more information on driving requirements, see Ontario Regulation 340/94 (s. 21.2).
