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

Physicians and optometrists are required to report any patient who may be suffering from a medical or visual condition that may impair their driving. Police may also report drivers who they feel may be medically unfit to drive.

  • Medical standards for class G drivers driving for commercial purposes in the US
    • 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).
