Report a medically unfit driver: Optometrists


Optometrists in Ontario are required by law to report to the Registrar of Motor Vehicles any individual who may be suffering from certain eye conditions that may make it dangerous to drive.

The law

Ontario has amended section 203 and 204 of the Highway Traffic Act (HTA) to introduce new mandatory reporting requirements for vision impairments.

Starting July 2018, optometrists must report the following vision conditions

  • A best corrected visual acuity that is below 20/50
  • A visual field that is less than 120 continuous degrees along the horizontal meridian, or less than 15 continuous degrees above and below fixation, or less than 60 degrees to either side of the vertical midline
  • Diplopia that is within 40 degrees of fixation point (in all directions) of primary position

Optometrists will have the discretionary authority to report vision conditions that, in their opinion, make it dangerous for a person to drive using the discretionary section of the reporting form.

For more information about mandatory reporting requirements and discretionary reporting authority, see Ontario’s Highway Traffic Act, section 203, and Ontario Regulation 340/94.
