MTO Service Commitment

Snow and Ice Control

Our goal

To meet the bare pavement standard after winter storms 90% of the time. The standard varies depending on winter traffic volume and road type. Some highways with low traffic remain snow packed for most of the winter. On these highways, excess snow is plowed off and sand is applied to improve friction.

Standard timeframes following the end of a storm are:

  • Eight hours for freeways and multi-lane highways, e.g. Highway 401, Queen Elizabeth Way, Highway 11 four-lane sections (Class 1).
  • Sixteen hours for high traffic volume, two-lane highways, e.g. Highway 17, Trans-Canada (Class 2).
  • Twenty-four hours for medium traffic volume, two-lane highways, e.g. Highway 35 (Class 3).
  • Twenty-four hours to centre bare for low volume, two-lane highways, e.g. Highway 516 (Class 4).

Ontario's snow and ice control standards are consistent with the best practices used across North America.

Our commitment to you

The Ministry of Transportation will continue to monitor contractors' compliance in clearing provincial highways before, during and after winter storms to ensure provincial highways are kept safe for winter travel.

Be aware, however, that in the winter:

  • A severe or long storm may delay restoring bare pavement, even with the best efforts of highway crews.
  • It may take up to eight hours for plows or sanders to begin servicing ramps and low-volume roads.
  • Extreme weather may result in the closing of highways.
  • Salt becomes ineffective for melting ice and snow at temperatures below minus 12 Celsius.

How you can help us help you

  • Remember, not all roads are maintained by the province.The Ministry of Transportation is responsible for provincial highways.
  • Adjust your driving to weather conditions. Weather conditions can be variable and unpredictable, placing extra demands on your vehicle and driving skills. Take the time to ensure you are well prepared for winter roads and always adjust your driving speed to existing conditions.
  • Review the winter driving tips on the ministry's web page http://www.mto.gov.on.ca/english/safety/winterdrive/winterdrive.shtml

Leave Room for Plows:

  • Remain a safe distance back from maintenance equipment when you see their blue flashing lights.
  • To do the job right, snowplows and salt and sand trucks must travel slower than regular traffic. Sight lines and visibility near a working snowplow are significantly reduced by blowing snow. Passing can be dangerous.

Respect Highway Closures:

  • Do not attempt to drive on closed highways until they are re-opened. Always obey emergency road closing signs and barriers and follow the directions of police officers. It's for your safety. Remember, it is against the law to drive on a closed highway.

Review winter road conditions information before driving, available on the ministry' website or through the Provincial Call Centre.
